nrf91_simple_tracker

[Digisoles]

Hi I am starting with nRF9160. I build and program "nrf91_simple_tracker," but while running, I got the following terminal output:

*** Booting Zephyr OS build v3.3.99-ncs1 ***
[00:00:00.254,028] .[0m<inf> Cellfund_Project: The nRF91 Simple Tracker Version 0.2.1 started

I am using nRF Connect SDK v2.7.0 with VSC using SparkFun nRF9160 Thing Plus.

Any hints?

Hello, 

Unfortunately, lesson 8 in the cellular fundementals course is not tested with nRF Connect SDK v2.7.0. Based on the output from your logs it does not look like you have built for v2.7.0. Can you please confirm?

I tested with v2.6.1 and had no issues building and running on my nRF9160DK. Building with v2.7.0 you should have the following output:

*** Booting nRF Connect SDK v2.7.0-5cb85570ca43 ***

Can you please confirm your setup? 

What SIM card are you using?

Kind regards,

Hello, and thank you very much for your help. I failed to uninstall SDK v2.4; I had already uninstalled it; however, when I develop an app, the file "app_update.bin" is no longer generated. Until now, I set "CONFIG_BOOTLOADER_MCUBOOT=y" in the prj.conf in order to generate that file.

Could you please help me?

I think we should stick to one issue in the ticket at first. Based on my last response, did you get it running?

Kind regards,
Øyvind
