Hello,
I’m trying to implement BG95-M2 in my current design. I have to connect to MQTT broker via NB-IoT. So far I have connection with network and I can connect to broker server by AT+QMTOPEN only by using IP address of server. Name is not recognized and translated by DNS. After that I’m using AT+QMTCONN to login, but I recive always error number 3. Below I’m posting part of log:
AT+QNWINFO
+QNWINFO: “NBIoT”,“26002”,“LTE BAND 20”,6397
OK
AT+QMTOPEN=0,“5.196.95.208”,1883
OK
+QMTOPEN: 0,0
AT+QMTCONN=0,“BC95user”
OK
AT+QMTCONN?
+QMTCONN: 0,2
OK
+QMTSTAT: 0,3
What can be wrong?
