Hello Quectel Support Team,
I am working on a project using the Quectel M95 GSM module. My current firmware revision is: M95FAR02A08
When I try to use the MQTT commands (for example, AT+QMTOPEN=?), the module returns +CME ERROR: 100 or ERROR. It seems my current firmware is an older version that does not support the built-in MQTT stack.
Could you please share the following files with me via email or a download link?
-
The latest M95 firmware that supports MQTT AT commands
-
QFlash upgrade tool
-
Latest MQTT Application Note matching the new firmware
-
Firmware upgrade guide
-
Release notes
Thank you in advance for your help!
