Greetings,
I am currently using the Cat. M1/NB IoT GNSS Shield and trying to connect to the mobile network.
I am simply using the arduino example for the portenta h7 board. However, the function GSM.begin() takes alot of time (more than one hour) then fails to connect. I used the same board, the same shield, the same antenna and the same code months ago and it worked perfectly. Now I'm having trouble trying to simply connect to the network. Has anyone encountered a similar problem ?
Does anyone have a solution or a way to debug this ?
Thank you.
