Issue with configuring BC35-G

IoT Modules LPWA Module
1

Hello everyone, I’m new to the use the NB-IOT product line of Quctel and recently got BC35-G in my hands. The module successfully registers to the NB-IoT network, but it seems it’s configured to send raw UDP data. I need to set it to MQTT mode, but all related AT commands reports error. The output from AT+CFG also is ‘Error’. I managed to upgrade to firmware version 1.3.5, but it doesn’t help.
Here is some output that might help:

OK

Please disregard the above, I found the issue -it’s in the terminal application I use.
