Hi,

I got two observation for my simcom module. And I conform I am using old firmware.
By using this firmware I unable to do the SSL/TLS configuration
But, my requirement I want to configure TLS MQTT Server.

And also I got confused with this command,
AT+CMQTTCONNECT=0,“tcp://test.mosquitto.org:1883”,60,1

And I know TLS configuration done once update module firmware,
But, I don’t know, how to configure this following server?

AT+CMQTTCONNECT=0,“tls://xxxx.net:8883”,60,1

But, This is not the proper as per the document CMQTTCONNECT command begin with "tcp://"

Please provide your feedback.

Hi @jayr6621,

I update the latest firmware and I done the ssl configuration. But, I unable to connect.

LE11B12SIM7600M22 - This is the latest firmware with TLS configuration.

As per tls (2.2.8 AT+CMQTTCONNECT Connect to MQTT server ) from document
(https://simcom.ee/documents/SIM7X00/SIM7500_SIM7600_SIM7800%20Series_MQTT_AT%20Command%20Manual_V1.00.pdf)

server address needs to start with tcp (but, we have tls). Because, TLS needs/working over TCP.

Thanks,
VinothS.
