Asset Tracker V2, connecting problem to AWS Iot

Minyaev

Hello,

I am trying to connect asset_tracker_v2 to my aws iot cloud with MQTT,

then storing this data in aws database, when i changing parameters to AWS Iot library,

i have a fatal error, i am not understanding why ?

  • I am workin whit nRF9160, thingy:91 and nRF9160_DK
  • I use nRF Connect SDK V1.8.0 whit SEGGER embedded Studio
  • I have an alredy existing AWS account
  • I have downloaded certificate successfully to µc

That is my configuration:

And that is my log output when building and running:
