Recently I purchased nRF9160 DK and I have a Vodafone Idea SIM (active). I followed the instructions precisely as per the Nordic infocenter but I am not able to connect my nRF9160DK to the nRF cloud. I tried to upload the latest modem and application firmware in the DK and 4 LEDs started blinking simultaneously after that. When I checked LTE link monitor the DK was rebooting every 5 seconds. As specified in the Nordic documentation I tried updating the certificate after the AT commands. Then I tried inserting the SIM card but LED1 was blinking instead of LED3. The LTE is not connecting as well even after waiting for several minutes. The sequence is --- LED1>LED2>LED4>LED2
I don't know whether it is the problem with DK or the problem with SIM
Can anyone please help me with this issue. I am attaching images for the reference.
