Hello, everybody!
encountered some problem.
the system has several end devices about 300
now there are about 20.
Data from devices is coming, but it is not possible to send a command like AT+…
in response come txack and ack
if 2-3 end devices are working, then the commands are sent.
in frame receives ConfirmedDataUp and Unconfirmed
I suspect that the case is in the configuration files, but the problem cannot be solved
