How do I send Logger Messages to my mobile instead of UART?

Hi Fernando,

Yes, the nRF Logger sample application works, but not for what I though you wanted to do. You could use NUS to transfer your logs and handle that on the phone side in your custom phone app (for instance using the nRF Logger library), but that may not be very useful for the reasons outlined in my previous post.

A better approach could be to use the flash backed, so that you will be able to store logs in cases where you are not able to transfer logs over BLE, and then transfer the logs when a connection is made. But how you do logging in the field is highly application dependent. If this is for logging in your lab / on your desk, it would certainly be better to use UART or RTT.

Hi Einar.

Thanks so much for your answer. Actually, the nRF Logger works, the thing is that it's just working with the NUS service, which I need for my project.

Regards,

Fernando M.

Hi,

I think you have misunderstood the nRF Logger. It is a library (and example application) for logging in Android applications. Not for receiving logs via Bluetooth or similar from an nRF.

There are ways to transfer logs wirelessly, but that is not really sensible for debugging (a whole lot of things need to work in order to get the logging working in that case, and when something fails you typically want logging, but that will then most likely break). Also, we do not provide any such system for logging in the nRF5 SDK (the logger module supports UART, RTT and flash).
