Nrf9160 board resets when connecting to NB-IoT.

[Navin Sankar]

 Currently I am testing the coap_client and https_client sample application with nrf9160 based custom board. But the board is continously resetting while searching for the network. But after 5 - 10 attempts connection is established with NB-IoT  and sample is working. When the new firmware is flashed again the reseting problem occurs. Attached the console log

Did you check the power supply?

[Martin Lesund]

Hi Navin,
Are you testing the applications with default settings?
if not what changes have you made?

What network are you trying to connect to? (+ what SIM card are you using?)

On some NB-IoT networks, we see that using "legacy PCO" can help things out.

e.g. put this configuration in the prj.conf file of the sample:

CONFIG_LTE_LEGACY_PCO_MODE=y

Are you able to connect to the network by just using AT-Client sample and sending AT-Commands?

[Navin Sankar]

Yeah. The issue is with power supply and programming cable connector. Since it is a custom board. For modem based application it's consumes more power compared to non-modem applications. Thanks for supporting.
