I want to control a ioio breakout for andriod via another android phone and ioio combination .....
Any ideas / thoughts and input generally is welcome .
Basically I would like remote control of as many channels as possible long distance like a android ioio combo rc set up with receiver and a transmitter / controller sending the control data to the radio controlled whatever ...
I intend to breakout of the android phone with the ioio to afford numerous gpio and thus control of stuff long range all controlled by a ioio controller set up attached to another android phone which is communicating ( some how ?.... Internet ?? ) to the first android phone and affording control through the ioio breakout which is inturn attached to the stuff to control.
I have looked at a arduino and gsm modem combo but there's only two pwm outputs which is no good especially when ioio has loads of servo outputs and a plethora of all else to boot hence I figure I best settle down and get started.
The 3g modem for arduino is a big investment beyond its value I thus far think hence ioio.
I appreciate that there's actually quite a lot to consider to have the arrangement all singing all dancing and I really know nothing of use beyond having a vague plan of attack and a general lack of direction so any input with abbreviations etc explained would be wicked as I have ADHD and otherwise waste ages reading how to to never actually recal what I've read unless its posed in a very logical progressive format.
A hundred thankx

Hi there,
I'm sorry but I don't find anything related to your question except this thread where you can ask directly: [APP][2.3.3+] IOIO Bluetooth Control Device - Android control hardware devices
Or you can start asking in one of this Q&A forum:
> Android Development and Hacking > Android Q&A, Help & Troubleshooting
or

Good luck

Hi,
I am trying to get up to speed on Bluetooth capabilities for my soon to arrive F10 (2011, 530d).
Does anyone have deep technical knowledge on the Bluetooth interface/version/capabilities of an F10 Bimmer?
Or know where can get hold of it? Does BMW provide a developer portal for 3rd party software developers or is it handled case-by-case with vendors like Apple, Microsoft, HTC, Nokia, Sony Ericsson etc.?
The reason for my inquiry is that I am trying to understand on a low level why so many phones differ in available capabilities when paired with a bimmer. It is of course related to the services exposed via the phone..but one should be able to tweek it
For instance only Symbian based phones seems to provide Office support like email, SMS etc. Datalink support is also lacking on many modern smartphones like iPhone and Android (not all versions but in general the support is limited).
(I am posting in the general Android forum since I have a HTC Desire...)
Regards
this is a good question, i to have run in to this. why is there such good support for iphone but the bmw office cant work with it? why no support for android? if you find any info on this let me know.
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?
Hi guys,
I tried to find similar threads or answer but none specifically addressing this question.
I want to detect whether sound is being played on the device in general, then hijack that audio stream to find the BPM in a separate android application. This may or may not include decompressing the audio stream and measuring it based on peaks/troughs in the sound wave. But the general idea, so far as I can tell, is to reroute the IO stream from applications using the sound card and pipe it to another application.
I know this is theoretically possible using android libraries like BASS by XMPlay, but I've never seen this in practice (I assume there's a good reason).
My gut feeling is that when the sound device is in use, the thread is basically locked down and you can't do much to it. This is the case in many operating systems (but not all!, including Linux based os), so would not be surprised if this question is left unanswered or just not possible.
Also an fyi; I'm very new to Android development but I have a plethora of experience in Java and lower level languages. It's very possible that many of my assumptions are way of the mark here. Any input would be greatly appreciated.
Cheers,

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

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 would like to create an IoT device by buying new, cheap android phones, strip them down and remove the screen, rebox into my own physical box, install a custom ROM without any bloatware (and that will boot without a screen!), and install my android app on the device to do stuff.
An example of a purpose for this could be a GPS tracker for a car. The box would be placed in the car, and record GPS and accelerometer readings, posting these readings back to a central server via the cellular network. (This is just a random example, so don't focus too much on the detail of this, but there are thousands of uses for a IoT board with the sensor, CPU, RAM, storage, and connectivity capabilities of a budget android smartphone)
The reason I want to use existing phones is that they are wonderful, mass produced, cheap devices with a variety of sensors I can use.
The reason I want to use Android is because it is because of the customization ability, and the mature development ecosystem.
To me, it seems an obvious thing to do, but I don't seem to be getting much joy trying to search for examples of this sort of thing (either here, or on the internet in general).
So some questions:
1. General thoughts? (Good idea? Am I missing some fundamental problem?)
2. What are the challenges of running Android without a screen connected?
3. Are there any custom ROMs you know of that specialize in this sort of thing?
(I've seen Google Brilo, but it still seems a bit early yet, and I really like the idea of just using the standard Android SDK to develop the app - and the abundance of help and information that comes with it)
Thanks!
