User Description Descriptor Example

[Hein]

Hi guys,

Is there a recent example that shows how to add user description descriptors to characteristics on S132 V5.1 ? I have tried the various methods I could find in the Q&A, but have not had any luck. 

Thanks!

I have gone through the exact same steps, and find there is no way to get a human readable descriptor to show next to a custom characteristic in NrfConnect.

That seems too implausible to be true -- there must be a way...??

Did you try the implementation in my last reply? 

It depends on what you mean by human readable, but the name "name" is there in hexadecimal reprecentation (0x6e 0x61 0x6d 0x65). nRF Connect for Desktop only supports hexadecimal view, but if you have your own mobile application it would be a small task to convert this to a "Human readable" text string.

I agree with you - we can see it in hex. However, We use nRFconnect as a tool for technicians, espc because of DFU - for that reason it would be great if they could also use it to quickly scan various services in human readable form...

Ps: many other BLE tools show the human Readable version of Characteristic when all-ascii - but of course they don’t have DFU...

nRF Connect is not intended for end users, but it is a development tool. Perhaps you want to have a look at nRF Toolbox. That page has links to the source code for Android and iOS. You can modify the application to display the ascii characters for the characteristic. 

I am sorry, but that is what we have at the moment.
