Dear NXP,

 

I am working on SIM7600 GSM module. I want to implement MQTT over this module.

 

But, I am not clear, How TLS will work with TCP ?

 

 

Please trying to understand my requirement,

 

         Toradex Apalis Imx6q with Board

                                 |

                     Mqtt Data Transfer

                                 |

                       TLS Cloud

                                 |  Yes                                        | No

            Start Data Transfer(Give 4G access)          Not give 4G access        

 

 

echo -e "AT+CMQTTCONNECT=0,\"tls://xxxx.net:8883\" ,20,1 \r\n" > /dev/ttyUSB3

 

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

 

But, I don't have the TCP server. And I don't know How TCP server will work with TLS

 

 

And also I attached the document for your reference.

https://simcom.ee/documents/SIM7X00/SIM7500_SIM7600_SIM7800%20Series_MQTT_AT%20Command%20Manual_V1.00.pdf 

 

If it possible please provide your ideas.

 

 

Thanks & Regards,

VinothS
