hello I hope that help… I don’t know which is your TCPConnectID have you try

//AT+QMTCFG="version",<TCPConnectID>,<mqtt_proto_ver>\r
AT+QMTCFG="version",0,3\r

I tried this command which is shown on the 1st picture with CME ERROR 3765 (invalid input value) :frowning_face:

I am sorry for insisting but

into the first picture the second param is 1 like this, the change is surrounded by triple *

AT+QMTCFG="version",***1***,3
I said you can try
AT+QMTCFG="version",***0***,3


this is because at previous command
//AT+QMTCFG="ssl",<tcpConnectID>,1,<ctx_index>
AT+QMTCFG="ssl",0,1,2
