Hi avm,

I am sorry that you are experiencing this.

I have two quick suggestions to try out:

1. Update to the latest modem firmware

2. Try to flash this Asset_tracker application:

 asset_tracker_updated.hex

(with nrfjprog: nrfjprog --program asset_tracker_updated.hex -f nrf91 -r --sectorerase --verify)

Let me know how it goes.

//Cheers

Hmm I'm getting this now too with the above asset_tracker_updated.hex file, here's my output from the Link Monitor

Any idea? Thx!

I do have the same issue here. Sometimes the asset tracker is able to connect but after a couple of second, it throws this error: 

NRF_CLOUD_EVT_TRANSPORT_DISCONNECTED

It was all working without any issues before updating to the newest modem. The at_command example runs without any issue. Is the asset tracker not compatible with the 0.6.8 modem? Is it possible to get an old modem version?

Thanks!

It looks like there was a issue with the secure boot. I've rebuilt and reflashed the secure boot and it's working.
