Hello,
We are using BC35-G module before and we can open a MQTT network using following AT command:
AT+QMTOPEN=0,“true-florist.cloudmqtt.com”,1883
However, we switch to BC95-CNV module because BC35-G is EOL and not available now. We use the same AT command to open the network but it fails and returns:
+QMTOPEN: 0,-1
Is there any advice to solve the open network fail problem? Thanks!
