Android Question Need an example of using USB OTG series ports on the latest and new libraries

[Lakhtin_V]

I read many posts on the forum and got confused about which library is better to use to exchange strings between two com ports on different devices. I plan to use the Lora modem on my USB OTG connector. I have already tested these modems through a regular USB terminal application, the exchange of strings is fine. Now I want to implement this inside my application, what example and which library should I choose. Waiting for your advice.

If your modem is implemented as a serial port then you can use felUsbSerial or UsbSerial libraries.
