Hi,
I have a dragino NB-IOt bee with the Quectel BG96 on an arduino and try to connect using a tmobile NB-IOT sim form the starter kit.
I can send AT commands to the unit and get proper response.
following this cookbook i do get an IP address but cannot ping anything. Can anyoune see what goes wrong here?
Thanks.
Here is my AT communication after a reset:
