what is Nordic UART Service TX and RX UUID? #2
Description
This is my working note.
A lot of example of 'micro:bit BLE sample' defines
const UART_TX_CHARACTERISTIC_UUID = "6e400002-b5a3-f393-e0a9-e50e24dcca9e";
const UART_RX_CHARACTERISTIC_UUID = "6e400003-b5a3-f393-e0a9-e50e24dcca9e";and micropad defines same.
But in Nordic UART document, there is a document as belows.
in this document, peer means micro:bit.
RX Characteristic (UUID: 6E400002-B5A3-F393-E0A9-E50E24DCCA9E)
The peer can send data to the device by writing to the RX Characteristic
TX Characteristic (UUID: 6E400003-B5A3-F393-E0A9-E50E24DCCA9E)
If the peer has enabled notifications for the TX Characteristic, the application can send data to the peer as notifications.
Why TX and RX is reversed?
