BG 96 & MQTT issue

HI there!

I use the Thnigsboard platform, with one way SSL, with just one certificate and an acces token “ZTVQUhvnRAPYRbw9O20x”

Using Mosquitto on Win10 I can connect to the platform with:

mosquitto_pub -d -h “thingsboard_server_address” -t “v1/devices/me/telemetry” -u “ZTVQUhvnRAPYRbw9O20x” -f “telemetry-data-as-object.json” -d --cafile mqttserver.pub.pem -p 8883 --insecure

With BG96, 06:08:17.488 -> Quectel BG96, Revision: BG96MAR02A07M1G

AT+QMTCFG=“SSL”, 0, 1, 2

AT+QFUPL=“ufs:mqttserver.pub.pem”,1258,100

AT+QSSLCFG=“cacert”,2,“ufs:mqttserver.pub.pem”

AT+QSSLCFG=“seclevel”,2,1

AT+QSSLCFG=“sslversion”,2,4

AT+QMTCFG=“version”,0,4

AT+QSSLCFG=“ciphersuite”,2,0XFFFF

AT+QSSLCFG=“ignorelocaltime”,1

AT+QMTOPEN=2, “thingsboard_server_address”,8883

AT+QMTCONN=2,“thingsboard_server_address”, “ZTVQUhvnRAPYRbw9O20x”

I get the error “+QMTSTAT: 2,1” I’m not sure if I use the proper connection method

These commands do not work either, but they are correct?
AT+QMTSUB=2,1,$v1/devices/me/attributes",2

AT+QMTPUB=2,0,0,0,v1/devices/me/telemetry"

All the best!

Hmm, after a few tries it seems that the certificate it can be uploaded ok, but still I get

“+QMTSTAT: 2,1”

Any ideas?

Thanks!
