LED3 doesn't blink after 'Erase all' with SES

[AK0817]

Hello all,

LED3 from nRF9160 DK doesn't blink after I erase all with SES.

what I've done so far:

Update successfully the modem to 1.1.0

Load the applikation 'nRF9160_DK_board_controller_FW.hex' to the nRF91

But LED3 still doesn't blink...

Any idea what the problem is?

Hi, 

Board controller firmware is for nrf52840. Which controls analogue switch that routes nRF9160 gpio to LEDs and Buttons and other peripheral. 

You should load asset_tracker sample application to nRF9160 which was preconfigured. Go to the Getting started section in the nRF Connect SDK documentation and check the Getting started with nRF9160 DK how to program Asset Tracker Application.
