Unable to open UUID definitions file

[pbrady]

I want to extend the list of known UUIDs with some custom definitions but I am unable to open the Open UUID definitions file.

I tried following the Adding UUID definitions, but no file is opened.

I also examined the install folder ( C:\Program Files (x86)\Nordic Semiconductor\nRF Connect ) but I was unable to find any .txt or .json files that might contain these definitions

Where do I find this file and how do I add custom definitions?

I have the same issue with nRFConnect 2.4.0 on Windows 10. Clicking "Open UUID Definitions File" doesn't open a file. I've verified that my file association for .json is to Notepad++, and that works from Explorer. I've verified that I have the file "%appdata%\nrfconnect\uuid_definitions.json", but nRFConnect doesn't appear to be loading or using it at all.

C:\Users\End User>dir "%appdata%\nrfconnect\uuid_definitions.json"

Hi!

Did you manage to solve this issue?

I don't have any issues opening the uuid_definitions.json file from nRF Connect (Tested with nRF Connect 2.4.0 on both Win 10 and Win 7).

Maybe you could check that your Bluetooth Low Energy app is updated to the latest version? This should be "Official, v2.2.0".
Also, notice that the file is located in %appdata%/roaming/nrfconnect/uuid_definitions.json.

Best regards,
Joakim.

Have you tried the suggestions above?

Can you find the uuid_definitions.json file in the nrfconnect directory?

Regards.
