Unable to connect to Cloud using Asset Tracker on nRF9160 DK

[mourad]

Hello,

I have an nRF9160 DK revision 1 with ibasis esim.

I wanted to  connect to cloud using the precompiled asset tracker lte files in your website :https://www.nordicsemi.com/Products/Development-hardware/nRF9160-DK/Download?lang=en#infotabs

I tried the nRF9160-DK application and modem firmware latest version (2022-06-02_880c82db) without any success ,the board keep resetting and all leds are off.

I switched to older version( 2020-04-29_bc7ade8b )like in this video : https://www.youtube.com/watch?v=rMvW3HXLErk&ab_channel=NordicSemiconductor

this time Led 3 toggled first then it switches off and Led 4 is on and got this error :nrf_cloud_transport: nct_input: failed -134

this is lte link monitor:

and this is the log file:

I use iBasis sim card and yes it's activated 

Ok thanks, Mourad! 

Could you please flash the ../img_app_bl/nrf9160dk_at_client_2022-06-02_880c82db.hex firmware, run through the Testing procedure described in the sample description and share the complete log? 

I would like to check some basic modem configurations. 

Cheers, 

Markus
