Thingy 91 no longer registers to the network after firmware update.

[Maciek]

Hello. After I updated the firmware on Thingy 91, it no longer registers on the network via LTE - the LTE indicator in LTE monitor blinks between yellow and red, and I get the CEREG 2 reply for the at command. It used to work with a preloaded example properly. My board version is 1.0.0. I'm using the iBasis SIM card, and I tried all available firmwares in the images_full folder, according to instructions on nordic tutorial.

Hi Maciek,

First, make sure that you have the latest modem firmware flashed to the Thingy:91.

Please state which network you are trying to connect to. Do you know if they support NB-IoT or LTE-M? (This can be checked here)

Please share the full log from LTE Link Monitor when you are running the application.

Best regards,

Martin L.

Hi Martin,

As you said, apparently the issue is either with nRF Cloud, or with the asset tracker sample. I managed to write other application that uses LTE and it works fine. I don't need to use nRF Cloud, so for me everything works fine now, though probably the Cloud issue remains unsolved. Anyway, thank you for your help!
