Android Question Detect and use UART port.

[Paolo Pini]

Hello,
I am working with an Allwinner A133 Android 10 module, this module has 4 UART ports that I would like to use to connect external devices, in this case Arduino, I don't know how to use B4A to identify these ports and how to manage them.
I have only found examples that rely on USB ports alone or in OTG.
Are there any examples for using these UART ports?

Thanks in advance

Hi, I had to abandon the project with Allwinner A133 because I also needed the STT and TTS functionality of google which is not present in the on-board software. I managed the project via OTG and Arduino.
