Android Question Strange issue with USB comms (felUsbSerial)

[cooperlegend]

Recently a device I link my B4A App to has changed (not sure what has changed)

But previous code using felUsbSerial that was working now seems to lock up

It does the initial port opening no problem

It then receives the first lot of data via serial_DataAvailable

Then serial_DataAvailable is not tiggered again, unless I do a re-connect

Any ideas?

Demo code found on another post attached...

Hard to say. Maybe the device doesn't send anything after the connection?

No it always sends the first pack(s) of data and then stops. It is very strange

Maybe updated some SDK of the MCU, or Arduino, libs version ?
