my orange pi 3b run on android 11
I have connect one usb port of the orange pi 3b (has 4 ports) to usb of an arduino nano
I want to sent throught the usb port of orange pi 3b the string "leds on" to arduino nano usb
and the arduino sends "ok" or "fail" as answer
the arduino has the chip CH340
the question
1) which library can i use with B4A on orange pi3b to send the string "leds on" from the usb port to arduino usb port?
arduino serial is 115200,n,8,1
2) is there any code example for b4a?
