asset_tracker: Connection was closed by the cloud.

[maaya_tech]

tag v1.1.0 (have done west update)
using SES 4.30c  as suggested by nrf connect  Compiled and flashed using SES
modem firmware mfw_nrf9160_1.1.1
downloaded and updated the certificate
added the device on nrf cloud

the device connects to the cloud.. I can see the details on nrfcloud account but it keeps disconnecting and rebooting and also how do I get the GPS to work ? It is supposed to be anabled by default

after disconnecting everything and connecting again.. retsarting the world, I was able to reflash.. I entered the command AT%XMONITOR=1,2 and at+CFUN=0

Removed the sim as mentioned above.. resset the board and started capture.. attached the tracefile and here's the log

[Didrik Rokhaug]

The point of removing the SIM was to get enough time before the reset to send the %XMODEMTRACE command.

When capturing the trace, you need to have the SIM in, so that the trace is able to capture the disconnect from the cloud.

Sorry if I was not clear.
