Bluetooth profile of ble_app_uart

[Fiske]

My application is based on the ble_app_uart demo. I want to get the BLE approval from the lab. The lab want me to tell them the Bluetooth profile of my application. How can I answer them.

Hi,

The ble_app_uart example uses the Nordic UART Service. This is a is a proprietary Bluetooth service, which means that it has a 128 bit UUID base, which is random generated (according to UUID generation spec), as compared to adopted profiles and services from Bluetooth SIG which are addressed using a 16 bit UUID. You can then define your profile as a custom/proprietary profile which uses the Nordic UART Service.

The 128-bit vendor-specific UUID of the Nordic UART Service is 6E400001-B5A3-F393-E0A9-E50E24DCCA9E. The service uses two characteristics: one for receiving and one for transmitting:

TX Characteristic (UUID: 6E400002-B5A3-F393-E0A9-E50E24DCCA9E)

RX Characteristic (UUID: 6E400003-B5A3-F393-E0A9-E50E24DCCA9E)
