Hii,
I am using the MC60 module as a client for the MQTT server. I am using MQTT with SSL. I have a problem while connecting to the server.
At,
AT+QMTCFG=“SSL”,0,1,2
I am giving tcpconnect ID as 0. And when I am using
AT+QMTOPEN=0,“test.mosquitto.org”,“8884”
the connection is not established when I am using the same tcpconnect ID.
But when I change the tcpconnect ID is other than 0, a connection is established.
Can anyone explain why this is happening?
Dear Sir,
Thanks for your inquiry in Quectel forum.
For yous issue, please doubel check whether your server can support SSL. Just as you have said that if you change another tcpconnectID with AT+QMTOPEN, it can connect successful, so it can said that another ID will not use the SSL setting. You also can check if it can connect successful with tcpcnnectID 0, but do not setting SSL parameters on ID 0. Thanks!
Mosquitto test server not work…
