What is the UUID that BLE_LoopbackUART is advertising

Windows phone application needs to know the serviceId (UUID) in the following format and it needs to be included in the appxmanifest file as well. But I have not been able to figure out how the UUID is formed in this case. Can someone help ?

Microsoft example application BluetoothRfCommChat is using this UUID: 00000001-1212-EFDE-1523-785FEABCD123

use UART Service to loopback anything received on the TX characteristic onto the RX. BLE, nRF UART

I'm way from desk, but you should be able to see all the UUID using:

  • Android App: nRF Master Control Panel (MCP)
  • iPhone App: LightBlue.

MCP shows the UUID of every service and characteristic as well.

Thank you. I just don't have any android or ios devices. So if someone could check this or explain how the UUID is calculated using these UART Service UUID defines.

UART Service = 6E400001-B5A3-F393-E0A9-E50E24DCCA9E

TX Characteristic = 6E400002-B5A3-F393-E0A9-E50E24DCCA9E

RX Characteristic = 6E400003-B5A3-F393-E0A9-E50E24DCCA9E
