| :name: BLE logging backend |
| :relevant-api: log_api log_backend bt_gatt |
| |
| Send log messages over BLE using the BLE logging backend. |
| |
| Overview |
| ******** |
| |
| Sample that demonstrates how to setup and use the BLE Logging backend. The |
| BLE Logger uses the NRF Connect SDK NUS service as UUID to make it compatible |
| with already existing apps to debug BLE connections over UART. |
| |
| The notification size of the ble backend buffer is dependent on the |
| transmission size of the mtu set with `CONFIG_BT_L2CAP_TX_MTU`. Be sure |
| to change this configuration to increase the logger throughput over BLE. |
| |
| Requirements |

| |
| * A board with BLE support |
| |
| Building and Running |
| ******************** |
| |
| This sample can be found under :zephyr_file:`samples/subsys/logging/ble_backend` in the |
| Zephyr tree. |
| |
| The BLE logger can be tested with the NRF Toolbox app or any similar app that can connect over |
| BLE and detect the NRF NUS UUID service. |
