How to add custom UUIDs definitions in nRF Connect for Mobile?

[zpm1066]

Hello,

In nRF Connect for Mobile, custom UUIDs show up as unknown, making it difficult to identify them easily.

Is there a way to add custom UUIDs, as can be done for example, on a Mac by adding the custom UUIDs to the "uuid_definitions.json" (located in folder /Users/username/Library/Application\ Support/nrfconnect)?

If not, How do I request an enhancement to nRF Connect for Mobile?

Thank you.

Though the app has no database of its own, instead it downloads the UUIDs from here. Meaning that there is one workaround. You can make a pull request with your own UUIDs, and the app will update itself with them.

Could you expand on why this doesn't work for you?

Hi Elfving,

My apologizes for letting a response slip through the "cracks".

Regarding the Thingy53 having the "unknown" names in the nRF Connect for Mobile replaced by actual UUID names, I was hoping that a pull request to get the UUIDs in wouldn't be needed as these UUIDs are not specific to my use case.

I would imagine that other Thingy53 users would also like to see "unknown" names replaced BME688 & BMI1749 standard UUIDs. Hence the request to the " nRF Connect for Mobile" dev team.

Could you send me a screenshot of these names showing up as uknown from your app?

Hi Elfving,

As per the previous recommendation from the nRF Connect for Mobile (iOS) team, it's best to raise a pull request for their dev team.

Would you be able to raise the pull request for me?  

Your colleague, Tiago Monte, provided the Thingy:53 Sensor Hub project a few years back in a Dev Zone blog ( https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/thingy-53-sensor-hub).

This would help to complete the project and would be quite useful to existing and new Thingy:53 customers.

Here are the screenshots from nRF Connect for Mobile (iOS) connected to the Thingy:53 running Sensor Hub application:

Here's the required Thingy:53 UUIDs that need to be added for the Thingy:53 Sensor Hub and the sensor characteristics (https://github.com/NordicSemiconductor/bluetooth-numbers-database).

Hi Elfving,

I'm not sure if you're on vacation. Did you get a chance to review above?


Thanks,
Ravi
