MC60/M66 MQTT Save credentials to NVRAM

IoT Modules GSM Module

Hi

Is it possible to save MQTT server and username & password to NVRAM to avoid having to pass these details over clear text on the UART when module is restarted?

This would apply to AT+QMTOPEN as well as AT+QMTCONN

Thanks!

Hi Xarion:
The server address and username、password cannot be saved to NVRAM.
If you don’t want the AT command to output at the UART port,you can use ATE0 to close the echo.

Thanks for the information, my questions is not about echo, the point is to hide the credentials from third party that can read on the UART port.
