Android Question connecting phone via serial usb to controller

[ralfkammel]

Hello,

I am a beginner in serial programming in B4A.

I try to comunicate with a controller using a USB cable and serial port
I want to send a few bytes from my phone to a contoller and the controller responds with a few bytes.

I have no idea how to do the programming.

Does anyone have an example?

I use a cable with FT312D chipset.
