Issue with Illuminance Characteristic (UUID 0x2AFB) Display in NRF Connect

[Ivenhor]

Hello,

We are developing a Bluetooth application that uses the Environmental Service to transmit various sensor data. Everything works correctly, but we have noticed an issue with the illuminance characteristic (UUID 0x2AFB) when using NRF Connect.

Specifically, NRF Connect displays this characteristic as "Unknown Characteristic", while other applications recognize it properly. Could you please clarify whether this is an issue with NRF Connect or if there is something else we should check on our side?

Thank you!

Hi,

The nRF Connect app is built with knowledge of some characteristics, but any other characteristics will show up as unknown. This cannot be changed (except by changing the app itself), so you will need to recognice the characteristic by the UUID value. (Note that nRF Connect is a development tool, so if you are making an app for an end customer, you would not show the data like this). See also this post.

Thank you.

We use NRF Connect for development and also to some extent for verification of the work done. The end user will not use it. Thank you for confirming that not all characteristics are recognized by the app.
