Hi. Can you show us a screenshot of your Master control panel or elaborate a bit more on what exactly it is you want to achieve? Is it the advertised name that you want to change? Then you can have a look at this tutorial: BLE Advertising, a beginner's tutorial.

Name of service is not something that you can set AFAIK. Some services are recognized (ex. HEART_RATE_SERVICE) because it has bluetooth SIG defined UUID.

Hi

If I understand you correctly you want to change the names that show up in the Service discovery window in MCP.

The names I have pointed to in the image above cannot be changed to whatever you like. Some services are predefined by Bluetooth SIG. See for example this list. These predefined services are the only services that will show up with a name in MCP.

A custom service will always show up like in the image above. Reading something like:

PrimaryService, Value: 23-D1-13-EF-12-23-45-56-78-89...........

What you can do however, is to add a User Description Characteristic as shown highlighted in the image above. Then you can include any name you want. Have a look at this thread to learn more about how to do it.

If you want to change the advertising name as shown in the image below I suggest that you read this tutorial.
