modem responds "OK" but
ignores any SABM(0) commands (even repeated 10 times)
until it receives <LF> character.
then it works
Sending AT+CMUX=0,0<CR><LF> doesnt help
To make MUX working I have to:
(modem responds OK)
Wait 0,5 sec
Send SABM(0) and other MUX session
My firmware is 10.00.002
Exactly the same Code for my application
works with Sagem HiLoNC and uBLOX LEON
without mentioned problem.
You have to fix baudrate with IPR=value
Autobauding and CMUX dont coexist well
Anyway its a bug because while entering
any binary protocol DATA/GPRS/MUX
current baudrate should be frozen,
and autobauding should be suspended by firmware.
you are right IPR must be fixed. Unfortunatly this limitation was removed from latest CMUX User Guide.
We will fix this on next User Guide.
