RS232 Interface to control hardware? - Galaxy Tab Q&A, Help & Troubleshooting

Hello!
I have a piece hardware which can be controlled via a RS232 interface.
Now I want to replace my controller, a computer, through the Galaxy Tab. Is there a way to communicate from the Galaxy Tab to a RS232 interface with a normal Android App and the right connection hardware/cable?
I found the "FlexSerial" cable. Is this what I need?

I think your challenge may be more driver/software related as opposed to being hardware/cable related. If you do get the cable sorted out, getting the Tab to communicate with the RS232 cables in the right way may be tricky. The flex serial cable is certainly a start but the function you are looking for is probably very specific to the device you want to control so finding the right Android app will not be easy. Just out of curiousity, what device is it?

There is an interface for controlling devices like robots, valves, timers, etc called andruino and it had a developer kit for programming and app creating. I think it will help your project.

ADK is not an option because the controlled hardware can't be changed.
@mkhattab:
Samsung Galaxy Tab Wi-Fi (P1010)
I have planned to development the Android App myself. But I read there are no API functions for a serial interface on Android :/

Are there any APIs / functions for USB interface? I think that's more likely than RS232 and in that case you can use a converter cable provided you have the correct drivers
http://www.amazon.co.uk/USB-RS232-Converter-Cable/dp/B00077DJIQ

Hm no, or maybe it works with a Bluetooth RFCOMM socket and a dongle like http://serialio.com/products/adaptors/BlueSnapStd.php at the hardware

Hi,
Like rangercaptain say, Arduino IMHO is a good choice, another link could be usefully:

Hope to help you

Hi rangercaptain,
Sorry, is not intentionally! i forgot to quote your post, i only added another link for further info

P.S.
I have change the post

I know Amigo, it sometimes happens to me.

I don't know anything for a fact about this subject but I will ask a question. Do you think the tab would have to be capable of going into USB host mode? Not as an external device (pc) controlling the tab but the tab controlling the external device (rs232 via USB via 30 pin proprietary Samsung data and charging port).

The second link I gave above is instructions for that. I thought the same as you, but I guess it's not what the op wants.

future options

Hi guys! Thanks for your valued labours! I know these are boring questions to you, but.......
Are there any chinks of light in the 'Bluetooth tunnel'?
Is there any possibility that in the future the sd port could be modified to sd/io?
Could an sd/io slot from another PDA be modified to fit in place of the sd or are there other reasons why this won't work?
And finally, will the upgrades mentioned on xda-developers.com work over here (GB)? And will they really allow me to connect wifi to my laptop, thus allowing me to use my XDA as a modem?
Sorry I'm so technically challenged.

No. Well, there's really small serial bluetooth adapters now, and someone just might stick one on the serial port. But then you'd still need drivers...

No clue, and the only ones to know are HTC, who haven't been articularly communicative about this device. SDIO slots are not a part you can just transplant. These are functions of chips or chipsets on the motherboard.
And finally, will the upgrades mentioned on xda-developers.com work over here (GB)? And will they really allow me to connect wifi to my laptop, thus allowing me to use my XDA as a modem?

The upgrade allows you to use the XDA as a modem through a serial cable or using IRDA (Infrared). It will not allow you to do anything using WaveLAN. The term 'Wireless Modem' refers to the fact that GPRS and GSM are wireless, I guess...
Replies to my queries
Thanks for replying to my queries, it is very frustrating that such an aesthetically pleasing & ground-breaking piece of kit like the XDA should have so many hurdles which prevent it being used to it's full advantage.
Such is life! Keep up the improvements! Thanks again! 8)
Remember it was designed 4 years ago, before Bluetooth and SDIO. Even SD had to stretch to get into it!
samsung i700
Samung i700 is the solution for those trying to use
bluetooth on xda. The other one is to wait for the
new xda with pocket pc 2003 maybe early next year.

Does anyone know anything about the i700, what it costs, when it's available (the Netherlands) etc. etc.

[PRJ][OS]Linux and Android on SE Xperia X1

This thread is here for information and discussion about the Linux kernel (and Linux based userspaces like Ångström distribution or google android.
If you have no clue what this is all about, click the above links and read a bit about it.
The xperia(kovsky) research information vital to porting the linux kernel is available at htc-linux.org
The kovsky is very similar to raphael, diamond and the other htc phones that are based on the QCT msm7xxxA chip. This is why the raphael/diamond development kernel code from the htc-linux project runs well on it.
Kovsky has its own machine type in the htc-msm-2.6.27 (see link above) branch now.
im kinda excited about this! if linux (& android) is able to run on the X1 smoothly, I'm definitely donating!
New thread = very good news.
If you need someone for testing then let me know.
I would be willing to donate as well.
Keep working hard everyone!
somehow i feel like setting up an X1 android version for it. since im more the "script" guy im rather useless for u if it comes to kernel development ^^
how stable and functional is the kernel so far?
and especialy, is the Wifi running allready?
hey decordes,
there is the question where to get the [email protected] files 0.8 and 1.0... (i have them. but dont know if i may provide these files while they are not from my self!)
a simple yes or no and they are available for the next years or not

afaik the wifi doesnt work. only usb0 which is laggy. (but works! you could ssh to the x1 per default.)
i am a little bit bussy at the moment (have to provide some sap-python-mysql-interface for productive use.)
but if i get spare time i will take a closer look at wifi...

I don't know many things on Kaiser device but if you read somewhere that it use a TI 1251 WLAN then... yes, it's the same.
I don't understand why do you correlate wifi and android booting
We're talking about this wifi chip just because it isn't supported in the linux-htc-kovsky package at the moment.

i was reading a combination of things,
-wifi not working and usb0 laggy.
-log readout over usb0
so i thought maybe for the log or something, nevermind

wifi not working on kaiser either so we cannot take the driver from there, but i dont think wifi has high priority...

its not related. i jsut read that the USB connection was kind of laggy so once i set up a working wifi connection i can continue working with SSH over wifi. that was the only reason.
ah... ok i think this was my intention.
most of the time i am waiting for usb0 to get any response! i cant read on the display them self... so the next needed feature for _me_ was to get a stable/responsible connection (like wifi

Hi,
very nice project. Maybe i could help out a bit
At least i may help testing and do some hardware discoveries, because i'm not a good kernel hacker.
Anyway i'm used to digg the kernel source and all the other stuff.
There are some questions though:
Those are introduced in the git repository of Mariusz "Aiv" Dalewski. Among other changes, it has the fully working xperia keyboard.

Is the git already accessible?

What's the exact state of USB connection right now?
Does it work on Raphael?
Concerning debugging:
Anything known about JTAG on Kovksy?
As you might know i'm addicted to this interface

The aiv code is htc-msm-2.6.27 branch plus xperia changes. I think he doesn't want to make it available publicly yet. I'm waiting for it too so I can push it to linuxtogo. You can pull the htc-msm-2.6.27 either way.
usbnet is same driver as used for raphael.
drivers/usb/msm_usb
For jtag, I think you need to wire it to the board manually.
For the raphael you can get a serial connection by making a cable that plugs in the usb port. Ask dreamkill about it. I don't know if it is wired the same way in xperia.
Hope this makes sense I have horrbile hangover

btw about wifi cant the driver from g1 be extracted?

Have to quote myself
The patch applies fine but after having a short glimpse, this one has been extracted from the SDK. No proper Kconfigs or Makefiles
So i don't think this huge patch is intended to go into kernel tree again.
AFAIK, there's also a lot of stuff for userland inside.
Insider may know more about it!
Perhaps for WIFI on the X1 it's better to start with a more clean driver.
You make have a look here:
http://osdir.com/ml/linux-wireless/2009-02/msg00390.html
I will try to integrate the patch to current 2.6.27-msm.
There's work to do of course, e.g. SDIO support and PM.

Right, It copies some revision (see date of file upload) of the android git ti1251. It should enable you to build the kernel module.

It's no big secret the 10M google ti1251 driver is crap and it might really be better to use that wl12xx as soon as they have the SDIO.

It can definitely be fixed, it's just a matter of how easily it can be done. Have you tried some of the unusual combinations people have come up with to get into download mode. For example removing the battery, holding power + volume down + home and then reinserting the battery whilst these buttons are held?
Also, if you can't get into download mode that doesn't mean you have to sell it as parts. Samsung will be able to repair it, if they can't tell what you did then perhaps they'll repair it for free under warranty.
Sometimes I just wonder why people try to install low-level software on their device that ISNT MEANT for their device. There is a reason, the captivate has a different model number and that is because it requires DIFFERENT software.
This comes close to me flashing the BIOS for an AMD motherboard on my X58 Intel motherboard.
reason for people installing other software is in my case because im STUPID !!! I stood almost 24 h reading forums in my country and stuff , and i googled ODIN the first link was this ODIN ONE CLIK i entered read about things there and it seamed to be for my phone, and from there we know the story. I did not think for one moment that the soft was for another phone. After i broke it i read all 42 pages and realized that.
I can't get the phone to do anything.... i can't charge it ... it's like the USB does not exist. If i start the phone unpluged, when i plug the usb in turns oFF , ass soon as i take out the USB it will start again to flash the AT&T logo...
I hope if i can't fix it, that SAMSUNG service will change it or can repair it and not charge a hunormus amount of money for that
you have give me hope telling that it can be fixed by samsung , and i still am opened for advices from u guys

I'm sorry for that. It's a little bit of frustration speaking there. But I guess you have a way bigger problem. Although that post about putting the right file on the SD seems interesting (but I haven't heard of anything like that before).
But if you can, returning the phone and hoping that samsung will fix it will be the easiest fix.

It's not impossible, but there are a few different things that must be looked at...
Gyroscope support
MoviNAND chip
NFC Chip
and so on.
I hope it is possible though.

Without a PC you are not going to fix it.

That's what I thought but for now I just need it or them to stop being able to remotely see, record, and even remotely control the phone.. I found the dirty object image or whatever.. it's a SM-A516U..

Hey, I have an old China phone that's more a paperweight than a phone because every time I connect it to the internet (via a safe network) it begins downloading viruses and weird apps that try to display apps, and if I happen to uninstall them, the phone simply bricks again and doesn't works unless I do a factory reset. Know if there's any way to fix it? I can't seem to be able to root it, let alone install a custom ROM.
It's got Android 5 I believe, a friend gave it to me because it can't be used for anything because of the viruses.
I'd make a thread but I don't even know where it is right now and I think on top of all the USB port is busted.

Yeah and the phone number to black out also... Not a good idea to display either information in a public forum...
