Hi Xda developers,
I might get involved in project during internship, where they want me to find way how to connect android device to custom made proprietary radio transmitter-receiver board without bluetooth or wifi, so it has to be direct wired connection.
This radio transmitter-receiver board has its own microchips and firmware so all low level work and functions will be done in this board alone.
Does anyone has idea how this could be done? is it possible to write some drivers (probably C) to communicate with this board over micro usb port present in all android devices? And than how could be data received over radio used in basic java-android application installed on device? (could this be done with use of a binary/text file as a link between these two programs?)
Thanks in advance
If nobody knows or has time to answer my questions, please give me some tips where to start searching for answers (websites, books, magazines .... )
Is it essential to learn Linux architecture properly before modifying anything in android?

hello everyone,
Can anyone make an application which sends ASCII code via bluetooth to a PC or a bluetooth module??
I really need it for my mechatronics project.
Thanks before
Does it have to be Bluetooth? You might be able to cobble something together over USB with the USB host driver.
I'd like wireless communication for the system since cable is kinda out of date...
But when time is running out... I guess USB will be OK. But for now, since I still have plenty of time, I'd go with wireless.
You could use the chroot method and install Ubuntu on your Nexus One. I don't know if it exposes the phone's Bluetooth interface, but it might be worth looking at since you could code up anything you want in any language if that were the case.
ermmm... it's kinda advance...
any URL to the guide maybe???
is there no ordinary apps or so?
Basic serial over bluetooth is done using the RFCOMM profile, details on how to write an app can be found here:

I'd guess you open a socket to the destination machine, just like normal network programming, just over bluetooth rather than tcp. Here is a stackoverflow article on the subject

I'll try my best to understad it

Hi Guys, i would like to know if someone is interested to work on a MANET running on android phones...
i have actual develop an specific Routing Protocol for Manets and simulated in Opnet and works well, i don't have to much skills on Java Programming or android software development and need help to develop the code for it...
basically the project is to run several android phone that will be able to use adhoc mode to create network and each node to be able repeat the signals to the next near node....
Regards
You may want to post code in C or C++ . No doubt someone would convert it into the proper Java android code. I suspect some of it would need to be wrapped anyway and that it's highly likely to require root access.
Finally
Finally someone working on Mobile Adhoc Network have acomplish a MANET protocol on android Phones, they have implemented an OLSR and BATMAN routing protocol..

Thank you serval for this implementation....
Hello everyone. I am an enthusiast on custom software hacks on Android and various other platforms. I know this question has been asked, but read to the end first before you answer.
What if you didn't want to use your device's data connection to tether your computer because you have available wifi, but no wireless card on your computer?
Is it possible to use your phone as your computer's wifi receiver?
And finally, would it be possible to bring this solution to both PC's and Macs alike? I know a solution exists for windows, and I ask this because I have a "Mac" as my primary system.
Thank you in advance for any help and solutions this community can provide.
I'm sure this is possible software and hardware-wise, but why? Don't they have little USB->Wifi adapters for around $20 usd?
Well, yes. But the point is to make the most out of the available hardware.
Don't get me wrong; I will probably go out and buy an adapter soon anyways. My understanding is that OSX has built-in compatibility with most adapters already.
Hello i just signed up to forum so i couldnt put this in the appropriate forum but my question is
I would like to make a small app to control a usb to serial adapter that has 4 relays built in that i would like to switch on and off. i was thinking usb to rs232 adapter i saw ftdi has an android samples and hardware that may be suitable i also saw several usb serial adapters on fleabay i couldnt put links to any of it being new and other places but im not sure what would be best suited for the task. i have eclipse running along with android studio but im no programmer by any stretch of the word im able to mostly edit code or do things along that line. I did use the app inventer tool on mit website to make a concept apk but thats as far as i got so far. anyone offering any info on where to start on the hardware side and also im not sure of what to use as far as a designer/programmer/compiler the only programming i have done has been visually so something along those lines would be great.
the concept app was 4 on off sliders one for each relay
any advice or help appreciated thanks
Ryan
I wanted to add some more info my device is a in the family of AN-21 U 4.2.2 car stereo dvd nav unit devices from china i am not rooted but already have one ftdi usb serial device installed and working(obd interface) so my feeling is im all set with the ftdi drivers.
moderator can this be moved to appropriate forum? or do I need to make 10 posts to be able to make one there myself?
I'd like to begin using xgoldmon or perhaps the MTK Catcher (or MTK engineering/dev tools) to begin watching a modem for weird or bad behavior.
However, I'd prefer to not devote an entire phone to this project, and I don't currently own any of the xgold chipset phones.
So, I wonder, are there any USB modems that were produced that run the xgold chipset that could be used with xgoldmon ? I would love to just stick a USB dongle into my linux laptop and just run xgoldmon there ... no phone involved.
If not, what about a USB modem that would work with MTK Catcher ?
Any other comments or suggestions are appreciated. If there is another tool out there that would allow me to get debug/modem/status information from a USB modem (sierra, etc.) that would be fine as well.
THanks.
... I wonder, does anyone know of a forum or board that would be better to post a question like this on ?
I am having a hard time finding forums where these topics are being discussed.
THanks.
