RM500Q-GL Protocols for AWS

Hello I wanted to reproduce something similar to what is explained in “the AWS IoT
Platform Access Guide” but in my RM500, so that I can connect to an AWS server and publish data, but when I send AT+QMTCFG=? it responds ERROR so I guess this module doesn’t have the MQTT AT commands implemented yet.
What is the most similar protocol I can use for this? Could you send me some useful documentation for this purpose? I only have the “Quectel_RG50xQRM5xxQ_Series_AT_Commands_Manual_V1.2”

Thank you in advice, Nicolas.

Or the firmware version of the module is not supported
Quectel_RG50xQ&RM5xxQ_Series_FILE_Application_Note_V1.0.pdf (478.1 KB)

Firmware is RM500QGLABR11A06M4G, do you know if there is any other that supports the MQTT AT commands for this module?

Thank you in advice, Nicolas.

RM500QGLABR11A06M4G is latest version
