MTCB/MTCC Rom issues with ALPconnect app and Bluetooth - MTCB Android Head Units General

Hi Guys
Would really appreciate some help with this one, i am sure it been covered to some degree in other threads.
Since owning my unit I have wanted one application to run and I am not fussed about anything else, the app is ALPconnect.
ALPconnect is a application that connects to my radar detector via BT 4.0 only so it displays all the information on the dash for radar frequencies.
https://play.google.com/store/apps/details?id=com.alpriority.alpconnect&hl=en
Due to the limitations in the Bluetooth, no current rom has been able to allow the application to turn the BT on and search for the ALPconnnect Module
http://www.alpriority.com/product/alpconnect-bluetooth-module-gen2/
Over on the other forum i am apart of http://radarandlaserforum.com, one member has spent upwards of 2000$ buying android head-units to see if this app would run and connect on it.
our small thread is ongoing at @ http://radarandlaserforum.com/showt...-InCar-Enetertainment-unit-ALPconnect-Testing about this issue.
I don't normally ask for help, but I could really use some help and I am sure others on the forum that purchased it for that reason would greatly appreciate it too.
This is the last information I received from agentdr8, thank you aswell

It's severely limited, when compared to any other Android device with BT. This is due to the OEM's choice of the BC5/BC6 module, and their poor BT implementation. Instead of routing BT audio traffic through the Android system, like a normal device would, they route it through the MCU. That would be fine on its own, except they route pretty much all BT interactions through the MCU, via serial AT commands, which is very non-standard. Simple things like pairing, or using SPP profile just don't work, or require a bit of finagling.
On top of that, there's code (at least in MTCB; dunno about newer MTCD) in MTCManager that filters which devices can pair via BT for OBD use. It checks the device name and if it starts with OBD, it will allow it to pass to the next step during pairing. I can only imagine they chose to do that so they could sell their companion BT OBD adapters with the headunits?
My XMTC module had accounted for this limitation in name-based filtering (apparently not the only limitation though; if your adapter was at least v1.4 it should work), but it hasn't been updated to work on any 2016 roms. Since I no longer have time to maintain that project, it's been open sourced on my github. The BT pieces could be extracted into their own module, but I thought I had read someone else (maybe MVG70?) had made a BT xposed module for these devices to try and address compatibility issues.

Just as a thought
Would the MTCB be able to support external USB BT 4.0 thus removing the need for the messy internal BT

I think it's been discussed before, and no one has successfully added an external BT adapter to these headunits.
Has that group tried the app on the Parrot Asteroid? I know it wasn't the highest rated Android headunit, but it might be more "standard" than how these ones are configured.

Thanks agentdr8, but it does not really help the ones that splashed out and bought the HuFei units
Is the reasoning behind the external BT not working because nobody is interested in making it work or is it not technically possible?

Since the kernel is not open source, there's very little hope of adding the necessary drivers to support external BT adapters. Aside from that, I don't believe the BT stack that is included in these roms is standard.
I won't say it's impossible, as given enough time and money, anything is possible. But I doubt it's something anyone here can address without the sources.

Guess the manufacturer is reluctant to release the source then.

Just a couple of questions
1.Do you know if any developer is currently working injecting the drivers into the kernel, as impossible as it sounds.
2.If the manufactures were to fix this issue, what things should they include to make external BT work?
3.Have any of the manufactures hinted at releasing the source and letting other developers fix the issue with custom roms
Just on another note
I have 30 emails from Eonon saying that their tech cannot do this and have assured me that.
We have our own brand and R&D department.
We use our software.

Which I don't believe for a second

I'm quite interested in getting this fixed as well - I have both an ODB2 adapter and Navdy that I'm unable to connect due to this limitation. And the fact that there's no available workaround via External BT is infuriating.

From my understanding, the only way to get this to work is through an external (USB) BT adapter, since the built-in BT stack sends everything through the MCU instead of directly to android. So enabling the proper USB drivers for BT in the Kernel would fix it. I'm not aware of any other USB devices that don't work (maybe gamepads or other HID devices, unconfirmed) so it seems they've cherry picked which USB devices to allow. Considering the otherwise hackable nature of these devices, it'd make sense to me to just enable all available USB devices and let us plug in whatever we want to plug in.

I'm in the same boat. I have an OBD adapter (Hondash) which refuses to pair. I've tried 2 Xposed modules which are supposed to sort this. I'm wondering if my particular issue is down to my 5.1.1 ROM so might try it on my old RK3066 4.4.4 HU which I gave to my Dad.
So I'm monitoring this thread in the hope a fix is found.

I am doubtful, I have contacted Klyde/Eonon/others and nobody is willing to release the kernel source code or address the issue.
So when someone gets a copy from Klyde/some reseller/MTC or whoever and a developer has the motivation to correct it, that can be the only solution.
I have given up hope on this one

Does anyone know the location in the Android file system where the Bluetooth pairings are saved?

FINALLY! Someone with a similar issue. I've got a Valentine One, and the BT module for android, (connecting using YaV1) and I've been trying to get my android unit to pair with it as well. In for potential solutions.

This question may be off topic, and I apologize for that, but are you referring to the app not being able to turn on BT and look for the adapter; just getting stuck at "Turning on bluetooth..."?
I have an OBDII scanner which I can pair no problem. When I use a specific app (OBD Card Doctor Pro (or reg)) and attempt to connect it, I get a prompt letting me know that an app wants to turn on BT. I click allow and then it just sits there and never does anything. Is that the problem ALPconnect has?
Torque does not prompt me with this and initiates the BT connection just fine.

The main issue here is that the bluetooth hardware is in effect emulated to the android subsystem for the nice bluetooth dialler front end so android has no real control over the bluetooth hardwrae. These headunits have some real downfalls and this is one of them What we need is to break this open and rewrite it. Without sources we can't do that. We could maybe dissasemble bits and replace them in code but the rom is factory odd and hacked to bits!

So this emulated effect is what causes my system get stuck "Turnning on bluetooth..." if I understand you correctly? There's no Android control over the BT hardware so the request is just lot in limbo?

Bluetooth connection issues

[/B]Hi, just received my TD2 last week and is enjoying it. I have one major issue though. In my car I have a Pioneer AVIC X3 system including GPS, AV and BT. Its the one with the motorized monitor.
Unfortunately it seems that HTC has chosen a different type of BT that is NOT compatible with my Pioneer system.
Does anyone know of any fixes ?
Maybe you can draw more attention to your thread by adding an appropriate title. Good luck finding a solution!
I had a very high end pioneer, never again.
With mine, the problem was that the pioneer won't recognise PDAs, but it will recognise Smartphones and mobile phones. (Each bluetooth device broadcasts what type of device it is.)
I actually told pioneer the problem, how to fix it, and their support would only say "your phone is not on the supported device list". After i put the effort in to help them improve their systems dramatically, they couldn't even be bothered to acknowledge it / forward it to the development people.... so I spent £600 on a kenwood, worked like a charm, Kenwood's bluetooth modules are made by parrot. (also the £70 kenwood I also have works great too)
There are some registry edits that work to make your phone identify itself as a smartphone, as long as it has the MS bluetooth stack, not sure the exact details though, I've not needed to do that since I got rid of the pioneer.
Hi Trinode,
Thanks a lot for your comments. If I was to try the registry edit thing... would you know a link somewhere where I can get this information ? Otherwise I'm probably forced to change the Pioneer system also.

[Q] Developers and BT

Which features of a ROM Kernel or Modem have the most influence on BT function. I recently purchased a Kenwood X994 for the car and the Captivate seems to have to be "connected" every time. Sometimes it loads the phone book, other times not. I have never been asked for a PIN code when pairing. Even after flashing a new ROM and reinitialization the Kenwood. It does work but even with th Gamin BT the connections were automatic.
I think the Developers might have an idea what influences the BT stack and if any ROM/Kernel/Modem is better in that regard.
If this post is in the wrong area please move it.
bump - I have the same concerns. Can't seem to find consistent bluetooth connection that was better than stock with lots of trying different roms with different modems and am totally confused on what directly affects the bluetooth connection

I am not trying to sell my ROM to you as I don't and am not here to make any money but I have not found a device that Phoenix Ultimate can not connect to. Just a thought for you.
Unless your making your own kernel thats special , their is some devices that it will have trouble connecting to, specifically certain car Bluetooth sets. this was a problem with every kernel I tried, and other users reported this also. I don't think it has anything to do at all with the Rom anyway,(it could, I didnt look into it too much), it think its an issue with kernels built from I9000 source.

Adam I have used (and am currenty trying out Phoenix Ultimate) and really find you ROMS useful, The BT works fine but the issue is I have to "connect" the phone even though it has been paired
The Kenwood X994 uses Parrot BT system which is supposed to be the best (which is why I chose the Kenwood LOL), I am just wondering why the device cannot auto connect when I get in the car as it did with the Garmin and the Honda. IS there a task I can set up using task manager?
Maybe its the Kenwood. But searches in that arena show no ill effect except with the Captivate and some Droids. IPhone is flawlwess with that system (wouldn't you know it) as are HTC phones it appears. I really hate having to select a phone based on BT in the car.

Which I thought as well so I flashed Cognition 4.2 and had the same issue...and decided to try Phoenix (GPS was terrible on Cog) Well I guess until I get another phone brand I will have to just make sure I connect the already paired devices. Although iPhone doesn't interest me...maybe HTC,

Getting Bluetooth Headset microphone working?

Any chance of one of the Devs having time to look into why the microphone input is not recognised or enabled on bt headsets in CM7?
Great progress has been made getting BT enabled, but I'd love to be able to Skype or record audio via BT...
Ill put a +1 on interest in this; but i know realistically, there are more critical things being fixed right now, so i am ok waiting..
I'm sure down the road, more devices will work, but I'm interested in the range issue. Is it a hardware issue (antenna) or is it a software?

software. the wifi shares the antenna with the BT.
I'm sure it's just a matter of time before the bluetooth is able to handle a microphone. That's what I'm waiting for. I am loving the latest CM7 stable 4-11-11.
That's the only thing my nook is missing.... mic. I've been through all the ROMS and nothing beats the CM7 ...IMO. I will be more than happy to test any kernels for bluetooth stacks that the developers may come up with. I'm not familiar with what all they have to overcome to make it work but I am rooting for them. All the hard work that has already gone into this is AMAZING!!!!!!!

Thank you! I love my Vibrant but GPS is a deal-breaker for me.

This does not improve the internal GPS radio in any way. This just gives us a switch to enable a external Bluetooth GPS receiver natively without buggy 3rd party apps. This causes apps such as Google maps or navigation to be much more accurate due to the dedicated GPS receiver hardware. Using my GlobatSat BT-359 I have managed a app reported 0 accuracy and almost always below a 5 foot area. This pretty much makes the internal GPS cry like a newborn baby...

so you'll need something extra for this to work?
On the download page, you will find step by step instructions on how to use it.
Basically, flash the rom, pair your gps mouse and just enable/disable GPS (using power widget for example).
But read the instructions at: http://iloki.nl/2011/08/06/update-06-08-2011/
it has screenshots and stuff
My rom basically gives you a switch to use our BT gps mouse as if it were your internal GPS. So you will get maximum compatibility , less battery drain and so on. Normally external receivers are way better than the ones that comes with your phone. My gps mouse is giving me 0.8m-2.0m accuracy for example. I was happy if I had 10m on my internal one. Most of the time I could get a lock (already tried soldering and so on).
To use my stuff the requirements are:
Galaxy S I9000/Vibrant -> binary builds. Other devices can be built from source.
NMEA 0813 capable GPS Mouse with Bluetooth Serial Port Profile (SPP)

Does it matter what chipset is being used in the mouse? By the way, I call it a GPS Receiver, "mouse" sounds strange to me, lol....
My unit has the SiRF StarIII chip and is also NMEA 0183.
GPS Protocol Default: NMEA 0183 (Secondary: SiRF binary)
GPS Output Data: SiRF binary >> position, velocity, altitude, status and control
NMEA 0183 MEA0183 V2.2 protocol, and supports commands GGA, GSA, GSV, RMC, VTG, GLL v2.2 (VTG and GLL are optional)
GPS transfer rate: Software command setting (Default : 38400,n,8,1 for NMEA )
Connection: Communication with host platform via Bluetooth Serial Port Profile
Using the 3rd party app "Bluetooth GPS Provider" from the market, it lets me actually select my chip type, in this case SiRF. Does this even matter in this case?
Nope doesn't really matter as long as they output nmea sentences (I haven't seen one that didn't. But it doesn't hurt to check before buying).
I myself am using a MTK2 chipset.
btw: google GPS Mouse ;-)

Yeah I already knew its called a mouse, I was just commenting that I do not like it. Its a GPS satelite receiver, or even a Wireless BT GPS puck would have been more appropriate I think... Come to think about it, mine is slightly smaller than a ice hockey puck but rectangled and very heavy for its size. I could easily play ice hockey with it, LOL....
Ok, so good NMEA support is all we need to worry about then. Most excellent...
EDIT: I hear MTK is better than SiRF, but not sure myself...

He has enabled this phone to take advantage of the common GPS Pucks you see around the world. They do not have a screen of their own, all they do is have the high quality GPS chip like MTK or SiRF StarIII or something similar, and they have their own antenna and they connect via Bluetooth to computers, laptops and smartphones. Smartphones are given very cheaply made low quality GPS systems, but some people like myself included would prefer a much higher quality GPS result on their phone.
Advantages:
1. MUCH higher quality GPS accuracy down to 1 foot or less.
2. Uses less power since Bluetooth is MUCH more power efficient. I had my GPS on over 8 hours yesterday and when I went to bed I was still at 54% battery left, using the built in GPS system my phone would have died long long before then.
3. Lets people use their current GPS puck/mouse. Now I can use my GlobalSat BT-359 GPS mouse. My Samsungs built in GPS system is non-existant and has never worked properly. Now I finally have real GPS, so props to the OP.
This OP in my opinion was very very clear in the first place... You shouldnt roll your eyes or wink like you know what your talking about unless you truly know what your talking about. All you did was show how much you are lacking up stairs. Figured I get to now roll my eyes at your stupid post.
A GPS Mouse is a GPS unit made for smartphones and laptops and they DO NOT have a screen of their own, there are hundreds of them made and have been for many many years. This is what he is doing, letting us use these awesome Bluetooth GPS devices so we can have much more accuracy and bettery battery savings. I see no harm in this.
@the OP, thanks for your great efforts as this was long over due...

I'm using this via Trigger - works BEAUTIFULLY on my BT 359 receiver. Although it was pretty confusing at first - after pairing initially it just said "paired but not connected" - needed to switch to the external first, then reboot, then turn on both BT and GPS (sometimes they turn on together in tandem, sometimes they don't..) before the light on the receiver indicated it was connected to the phone. And even then, it's still reported as not paired.
But that aside, this is ROCKING. I would tell you how accurate of locks I'm getting but GPS Test is freaking out (which seems to have been fixed and needs to be implemented in Trigger)
What are the odds of getting this into CM7 mainline?

It reports itself as "Paired but not connected", not as not paired. I mentioned this somewhere else I think in the Trigger thread but now I cant find it. I believe it cant report itself as connected because it does not use a constant on connection similar to that of a BT Headset would. I believe the puck sends data at on/off intervals to short for the phone to display a connection. Just my theory though... My BT Headset on the other hand causes the phone to report as connected, but I think that's because its a constant connection, as obviously an on/off connection would be detrimental to transmitting voice... lol
I can't wait to get this in cm7 source myself, but I wont hold my breath. I wonder if there is anyone we can email to get this pushed along quicker?
Don't worry about paired but not connected message. The most important thing is that is it paired.
Connected is represented by the GPS icon.
flashing -> connected and waiting for fix, or temp lost a fix
solid -> connected and fix
none -> no connection.
Just pay attention to you gps icon and you should be fine. The connection should be there all the time, a fix can be lost temporary if you're going through a long tunnel.
It's generally best to first turn on gps and then enable it on your phone (handshake attempts are initiated from the phone). The first handshake attempt might failed otherwise and you have to wait a little bit for the retry. But eventually it will connect.
New vibrant rom is being build, should be up shortly.
This removes the reboot requirement when switching gps sources. Yes it means no more rebooting

Tyre Pressure Monitoring System (TPMS) For MTCB Head Units

TPMS has beenn mentioned a few times in the original thread, but AFAIK no one has managed to find out how/if any TPMS modules will work. I bought a TPMS module from Klyde, it comes with 4 valve caps and a strange mini USB thing that I assume allows you to plug another mini USB device into the unit at the same time.
Unfortunately I cant get it to work with the built in TPMS app that started appearing in ROMs from June either on my old unit or my new one, I ve tried searching for the device in the BT app and the BT in settings but I get nothing, I m awaiting a response from Klyde.
If anyone has any ideas on how to get it to work then let me know, but its good to see TPMS hardware available for these devices - even if its not working . . yet !
Can you share link from TPMS module?
My brain is stuck what is TPMS? I am sure I should know but i don't get it
Guess youre talking about Tire Pressure Metering Sensor?
would you probably add a hint to your OP and title so others know what you mean? Remeber the non-english-speakers here
Yes this is it (Tire Pressure Metering Sensor).

I m not sure if its BT or maybe NFC or something. I ll report back with results when I get it to to work
Does anybody try this TPMS solution with his HU?

Does the app work in landscape mode?
Can the app start with background mode?
Does the external (valve cap) sensor show accurate value?
I have been using this TPMS system in Volkswagen Polo and my MTCB head unit since 3 months now and couldn't be happier with it.
It activates when you press the button because it invokes the reverse camera display source every time you call it into action.

I have tried these two models purchased at Amazon and they work perfectly. I have them installed on my cars.
The only drawback is that you need Bluetooth 4.0 and HuiFei radio does not have it. I have commissioned an RX USB Bluetooth for Android on Deal Extreme, to see if it works.
So far I'm seeing it in my S5 Galaxy.

Dont know, ask the seller.
But in any case if it works with a Joyous unit it will work with ANY MTCB head unit. There is no such thing as a "Joying" head unit - Joying/CarJoying are simply re-sellers of Shenzhen Joyous head units.

Yes I think.
It looks made specifically for these HUs. So I supposed they tested them.
And screens look like built-in TPMS app that I got preinstaled on my HU (KGL). So I supposed it should work.
But I would preffer ecternal sensors, not ibternal ones. I have 4x4 which reqiires regular tire rotation and ibternal sensors are not suitable as I would need to remove and refit them on every tire rotation.
Is there external versio? I couldnt find it on AlliExpress.
The one I mentioned in my first post has valve mounted sensors and obviously works with MTCB head units

Why? Sure, if they are somehow hard coded to location its sort of funny when they might not match the picture, but you only have 4 tires. Its pretty easy to check them when they are low.
You want internal sensors for TPMS. Less chance for losing them.

I understand the point about tire rotation and internal sensors. Would it be possible to make the same rotation in the app, since all sensors are doing the same thing anyway? Eg. If you rotate your right front to right rear, make the same in the app to correspond with the sensor location?

Yes, mapping is possible. Depends on product.

Hi All,
I have also interest for this. Somebody could give some information ? It works, or any other bluetooth type, using with external attached bluetooth 4.0 dongle ?
Well, I found out most of the connections for the TPMS as Klyde didnt send me a lead - power and ground were easy same as the DAB box, then, as its just a mini usb connection its just data + and data -, I know where the one of those wires goes, and narrowed it down to 2 pins for the other, I ve tried both pins and several versions of the TPMS app, but cant get anything. I ve tried looking for BT devices on my phone I thought I found 1 but my phone wouldnt connect and the headunit's BT wouldnt see it, my phone wouldnt connect and after removing all the batteries on the TPMS it still showed up so it couldnt be that. Totally stumped, just cant get it to work.
TPMS-Type
Let me inform you that for some time I'm trying to find a TPMS system that works well with Android auto MTCB-C I have made several purchases and placements from various vendors I will mention my experience to help future stakeholders.
For GS, KD, and JY machines, the following set works very well:

It has its own very friendly app and it works with automatic start-up in the background and immediately informs if something goes wrong with the tires of the car, I recommend it for the above!
But last time I discovered another type with external valves that works very well with a Klyde machine and that's it:

I believe I helped my friends.

Thanks for your post - I have the Last type, Klyde themselves supplied me with it, but they did not send me the lead and they did not reply to me when I asked for it, so I had to make one, but I still cannot get it to work, could you post a picture of the lead (the end that plugs into the head unit) so I can see which wires go where (I have seen the picture in your 3rd link before, but I cannot see where all the wires go) ?
