nRF Logger

Nordic Semiconductor ASA

About this app

nRF Logger lets developers view log sessions created by other apps through the nRF Logger API, available on GitHub. nRF Connect and nRF Toolbox from Nordic Semiconductor use the API to record connection events.

With nRF Logger installed, you can debug your app directly on the device, with no computer connected, to get the detailed information you need to diagnose an issue.

6 log levels are supported:
- DEBUG
- VERBOSE
- INFO
- APPLICATION
- WARNING
- ERROR

A log session may be marked with a flag or given a description to easily find it in the future.

Public API:
The public nRF Logger API has been released on GitHub: https://github.com/nordicsemi/nRF-Logger-API which allows to create log sessions from 3rd-party applications. Check GitHub site for more information and example.

Ratings and reviews

Great app.. Few suggestions.. 1. Save the log directly in device memory, as sometime when data is huge, it can't able to save or share the data. 2. Add option to select the type of data needs to be log.

I have reworded it many times. regardless of any rewording it was epic. At least take care of my boys. Paying child support was never an issue. And truly I'm not even mad about this app. it was perfectly planned and performed. Sad yes, you have the prize. Take GOOD care it.

Extremely plain; no clear instructions on actual usage. App appears entirely non functional
