I’m trying to change the baudrate of the HL8518 to the maximum value in combination with CMUX: 921600 (AT+IPR)
According to the specifications, CMUX supports transmission up to 1Mbit/s (no sure why this is not 921600??)
However after a few seconds the CMUX just explodes and the module start responding in non-cmux packages.
Is 92600 not supported for CMUX? 230400 seems to work fine
