I am using a Quectel EC25 (Revision: EC25ECGAR06A06M1G) and found that MQTT AT commands (AT+QMTOPEN, AT+QMTCONN, AT+QMTPUB, etc.) are missing from the supported commands list (AT+CLAC). This prevents me from connecting to an MQTT broker directly. Could you please confirm if there is a firmware version for my hardware revision that supports MQTT AT commands? If so, kindly provide the compatible firmware, along with guidelines and procedures for updating. Screenshot of AT+CLAC output is attached for reference. >> AT+CLAC

Hi ,
The latest version of the AT+CLAC command no longer supports it. I can’t test it locally.
Please provide the return value of AT+QGMR.
Also, please execute the following command:If you get the following return value, your version supports these commands.
AT+QMTOPEN=?
AT+QMTCONN=?
AT+QMTPUB=?
