Ledger Nano Gen5
| Identifier Type | Mode/Service | Value |
|---|---|---|

Bluetooth: Nano Gen5 devices may use one of two BLE identifier sets. The DMK automatically detects which set is used by the device.
BLE Identifier Set 1:
| Identifier Type | Service | Value |
|---|---|---|
| BLE Service UUID | Main | 13d63400-2c97-8004-0000-4c6564676572 |
| BLE Characteristic UUID | Notify | 13d63400-2c97-8004-0001-4c6564676572 |
| BLE Characteristic UUID | Write | 13d63400-2c97-8004-0002-4c6564676572 |
| BLE Characteristic UUID | Write Command | 13d63400-2c97-8004-0003-4c6564676572 |
BLE Identifier Set 2 (this happens rarely, only in Bootloader Mode, and only in early versions of the OS):
| Identifier Type | Service | Value |
|---|---|---|
| BLE Service UUID | Main | 13d63400-2c97-9004-0000-4c6564676572 |
| BLE Characteristic UUID | Notify | 13d63400-2c97-9004-0001-4c6564676572 |
| BLE Characteristic UUID | Write | 13d63400-2c97-9004-0002-4c6564676572 |
| BLE Characteristic UUID | Write Command | 13d63400-2c97-9004-0003-4c6564676572 |
Usage Notes
- Normal Mode: Standard device operation
- Bootloader Mode: Device firmware update mode
- Notify Characteristic: Receives data from device
- Write Characteristic: Sends data with response
- Write Command Characteristic: Sends data without response
