I would like to connect tls(Transport Layer Security) server with sim7600e,

AT+CMQTTCONNECT=0,tls://xxxx.net:8883

How can i connect it to this server?

As per this document,

Thanks & Regards,

toradex_apalis6q:/ # echo -e “AT+CMQTTCONNECT=0,“tls://xxxxx.net:8883” ,20,1 \r\n” > /dev/ttyUSB3

toradex_apalis6q:/ #

Hi

Is there any firmware update need ?

Any update?

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 I want the latest firmware for SIM7600E module. If it possible provide the link. Thank you.

Now, I am using firmware LE11B07SIM7600M22. I want the latest firmware. Please provide the link if it possible.

Thanks & Regards,
VinothS.

Drop mail to SIMCOM support. You would get which one you need. Its really that simple.

Thank you for the reply.

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.

That’s completely new to me… Haven’t tried it yet… I can try it on 7500E. once I will have some time…
