Testing the application
The next step after compiling and programming your application is to test it. Nordic Semiconductor
provides its own testing tool, nRF Connect, which is available both for mobile and for desktop.
10.1 Testing with a mobile device
If you have a mobile device that supports Bluetooth Low Energy, download the nRF Connect app from
Google Play or App Store to test your application.
The following procedure assumes that you have programmed the ble_app_uart example from the nRF5
SDK. Steps for testing other examples are similar. See the testing instructions for each example in the nRF5
SDK documentation for more information.
1. Download and install nRF Connect from Google Play or App Store.
2. Open nRF Connect.
3. Make sure that the DK is running the ble_app_uart example.
LED1 should be blinking every 2 seconds, indicating that it is advertising.
4. Tap Scan.
5. Find the device and tap Connect.
The default device name for the ble_app_uart example is "Nordic_UART".
6. When connected, tap the options button below the device name and select Enable services.
This example communicates over Bluetooth Low Energy using the Nordic UART Service (NUS).
7. Tap the options button and select Show log.
