Android Question how to send characters to usb ?

[fgh3966]

Hello everybody.

I want to send 5 characters by usb device with FelUsbSerial library.
I read documentation about FelUsbSerial library but i don't understand if is necessary to initialize the library to transmit characters ?
I'm looking for an example code to generate one or more characters.

Thank in advance.

Are you connecting a usb to serial converter?

There is a small example here: https://www.b4x.com/android/forum/threads/felusbserial-alternative-usb-serial-library.62216/#content
