Hi,
I’m using firmware BG95M5LAR02A03_01.201.01.201 .
The AT+CMUX=0 command returns OK.
However, the cmux does not really work.
I’m wondering if this is a known issue?
Do you have new firmware to fix this issue?
The workaround is adding a small delay after got OK response of "AT+CMUX=0"command.
If you send first command too quickly, the CMUX just dead.
This looks like a firmware bug as it should allow next command immediately after got OK response.
