I am using P822601 board (with nRF9160 chip).
Sample project "Serial lte modem" (SDK 1.8).
I'm trying to connect to a test mqtt broker (mosquitto) using AT commands via LTE Link Monitor, but with no success.
Using the "MQTT_AT_commands.rst" document, I similarly prepared a command to connect:
Fullscreen
1
AT#XMQTTCON=1,"mqtt.mosquitto.org","SJ","SJ75747723","test.mosquitto.org",1883
But the result for the command is always the same: ERROR.
I'm not sure about the sequence of AT commands needed to work correctly with MQTT.
1) Could you please indicate the necessary sequence of commands required for the correct configuration and work with MQTT.
2) The SIM card (iBASIS eSIM) used can be deactivated for some reason?
