nrf-9160 DK always disconnected

Antonioudakis Theodoros

Hi,

 I have added a nrf-9160 DK device to nrf cloud and it is always is shown as disconnected (disconnect reason MQTT_KEEP_ALINE_TIMEOUT ).

Previously i have updated the last modem and applicaction firmware. Moreover when i open the LTE Link Monitor and I enter an AT command I always get the following error:

'AT+CFUN?' timed out

    The reason of first problem was that the signal was not good enough. I want in another place and it connected just fine.

    The second problem, AT commands I mean, it happened when I updated the modem (mfw_nrf9160_1.3.1.zip) and application firmware of the asset tracker (nrf9160dk_asset_tracker_nbiot_2021-10-20_d29f1dde.hex). After that it always send me the message Error: 'AT+CFUN? ' timed out on LTE Link Monitor
