Hi. I’m trying to connect to the MQTT broker “test.mosquitto.org” using the Quectel M65 GSM module but I always get the +QMTCONN: 0,0,5 error code followed by the +QMTSTAT: 0,4 whatever ClienID I wrote. What is the problem please ?
there are the commands I wrote
AT+QMTOPEN=0,"test.mosquitto.org",1883 OK +QMTOPEN: 0,0 AT+QMTCONN=0,"hermannDutrone" OK +QMTCONN: 0,0,5 +QMTSTAT: 0,4
