modem init failed (nrf 9160)

Errors on calling "lte_lc_init()"

Does anyone know what the corresponding error codes mean, or what could be done to debug the cause?

Thank you very much.

Hello, 

what version of the nRF Connect SDK are you building with?  Are you testing with a sample or your own custom project? Is this custom hardware or a development kit? Can you please provide more information on you whole setup?

Kind regards,
Øyvind

I tried running the lte_ble_gateway example now to test establishing a lte connection using the same hardware but the nRF Connect SDK V 2.9.0 and Toolchain V 2.9.0, but there the following messages were shown:

with cause #15 being: No suitable cells in tracking area

I tried 2 different SIM Cards as well as 2 antennas and 2 boards, but the issues remains. Is it possible this is an certificate problem?

Hi,

 

Are you certain that you have LTE-M coverage in your area? Looks like the network rejects it.

Try setting CONFIG_LTE_NETWORK_MODE_NBIOT_GPS=y

 

Kind regards,

Håkon
