Hello Everyone,

I have tried with EC200U, from series MQTT application Note example of MQTT operation without SSL where I have given AT commands

AT+QMTOPEN=0,“”,8883
ok
+QMTOPEN: 0,0

AT+QMTCONN=0,“ec200”,“YM_DEVICE_01”,“Password@123”

+QMTCONN: 0,1

most of time I got error
+QMTCONN: 0,1
+QMTSTAT: 0,1

Please reply to this if anyone has solved this error or published data on Azure IoT hub using EC200cn-u AT commands.
Thanks

Dear customer,
Per your log, it looks like server close the connection. If the client there is no actions in specified periods. Server may close the connection to save resource. There is no timestamp in your log. Please check if your aplication is working in this situation. If yes, you need re-connect server.

My concern is it my flow is right to publish data on Azure cloud?

As I am not executing the AT+QMTCFG=" “,0,” “,” “,” " AT command mentioned in example for without SSL, but is this compulsory to execute this command then, how should I run it for Azure cloud?

Although I have executed following commands

AT+QMTCFG="keepalive",0,120

OK

AT+QMTCFG="version",0,4

OK

AT+QMTCFG="session",0,1

OK

AT+QMTCFG="timeout",0,5,10,1

OK
AT+QMTCFG="will",0,0,0,0,"",""

OK

AT+QMTOPEN=0,"<URL>",8883

OK

+QMTOPEN: 0,0

AT+QMTCONN=0,"Test","<USERNAME>","<PASSWORD>"

OK

+QMTCONN: 0,1

+QMTSTAT: 0,1

@rodney.wang suggest me the flow of AT commands to publish data on azure IoT hub.
Thanks.
