M95 - MQTT Operation without SSL

I’m having a project doing M95 module with MQTT feature
when I send two AT commands “AT+QMTOPEN=?\r\n” and “AT+QMTCFG=?\r\n”, it always responds “error”
I’ve already init it

receive: +CME ERROR: 100

send: AT+QMTCFG=?
receive: +CME ERROR: 100

send: AT
receive: OK

send: ATE0
receive: OK

Has anyone ever done and had the same problem?
Thanks for watching!


How is going on? Unfortunately, M95 doesn’t support MQTT protocol.

update your firmware to M95FAR03A03.
