M66_DS modem gives +CME:100 error for AT commands

IoT Modules GSM Module

Hi guys,

I tried AT+QMTCFG=? in my quectel M66-Ds modem after trying out AT command, which gave OK as response.

Reference: Quectel_GSM_MQTT_Application_Note_V1.2.pdf

But for Mqtt commands I am getting +CME:100 error.

1.Does M66-Ds support Mqtt?
2.If yes ,what are the AT commands I have to trigger before MQTT commands?

Kindly suggest proper steps to establish my Mqtt connection.Thanks in advance
