Raspberry pi 3 GPIO with android

[wiss...@gmail.com]

Hello, is it possible to use Raspberry pi 3 GPIO with android OS? 

[Igor Kalkov]

It should be possible. Did you check if the corresponding sysfs is available like the one on Linux?

Hello, I'm looking for the same, I couldn't find the sysfs. Did you figured out how to do it?

[Thien Pow Chong]

the GPIO is connected as Serial Port.  so you need to develop the android app that check a serial connection via UsbManager... that will do.

Hello Thien, could you please vive US an exemple how to read and write into gpio? Thank you

[Sergio]

I been able to access the sys files through adb, here there's an example for another board but it works as well in the Rpi3

@Sergio, which Android distribution did you test it with?

[Sergio]

I used rtandroid-7.1-20161102-rpi3

I installed a terminal emulator app (Termux) on pi 3 and executed the following:

#Pin 11 is GPIO17 (BCM numbering)

su
echo "17" >/sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio17/direction
echo /sys/class/gpio/gpio17/value
echo 1 > /sys/class/gpio/gpio17/value
echo 0 > /sys/class/gpio/gpio17/value

Works like a treat. Next step would be to figure out how to do it in an Android app.

We are working on a public API. I think it will take us a couple more weeks.

Until then you can just use Java FileInputStream / FileOutputStream to read the value file.

I guess that works! Do you think that an app using this sdk could find raspberry pi 3 GPIOs?

The following sample worked on rpi3b+ with pie, including SELinux configuration.
