Control GPIO on 3g-IOT

stancom

Hello,
I want control GPIO of board Orange Pi 3G-IOt.
I can develop apps with Windev (French editor) or Xamarin. But I found no information how to drive a GPIO through an application under android?
I need to read data on serials port too, same problem...
Is someone has some information

thank you in advance

It seems GPIO and other functionality are unusable on 3G-IOT and 4G-IOT like it 's explain in this post:

For me these board are unusable for my project. I will go back on Raspberry, perhaps more expensive but everything is functional
it's really a shame that design these boards with a lot of option and there is no support to make them evolve

I have the same problem but it is necessary to be root. And no idea how in this OPI.
Example GIOP COMMAND:
# echo "-wdir 24 0" > /sys/devices/virtual/misc/mtgpio/pin
# echo "-wdout 24 1" > /sys/devices/virtual/misc/mtgpio/pin<
link information.  

you know how?
