In the Ble peripheral/blinky example if i add another led , i am not getting the UI for the predefined led3 option instead i must enter the value 00 or 01.How must i get the ui?

Does the ui depend on the app design(nrf connect app) or on writing data in the characteristics. For the predifined i am getting a switch but for the one i added i have to type 00 or 01.i have attached image for reference How do i get the UI used for default led. And how do i get the UI on the nrf cloud?On the cloud i can only see the uuid

Hi,

Yes, it depends on how nRF Connect interprets UUIDs. I assume you mean this GUI:

The nRF Connect app is hardcoded to interpret the UUID 0x1523 as the LED button service. The same way it is hardcoded to interpret 0x1524 as the button characteristic and 0x1525 as LED characteristic.

If you add another characteristic with UUID 0x1527, nRF Connect doesn't know that you want to make a button characteristic. Hence, it shows you the generic dialog box allowing you to type in values or strings.

Unfortunately it is the same thing there.

is it it possible to modify cloud service to display buttons an all for my application?

Hi, sorry for the late response.

You can add several cards with buttons in nRF Cloud, but if you have more than one button there is no way of distinguishing between them, so it won't work as you intend. It is not possible to add cards with custom services either, so currently I can't see any way of achieving what you want with nRF Cloud or nRF Connect.
