BLEPeripheral Arduino Library
The nRF5 board definitions will allow you to program the nRF52832 and toggle its GPIO, but it doesn't include any Bluetooth support. For that, we recommend grabbing the BLEPeripheral Arduino library.
The BLEPeripheral library can be installed from Arduino's Library Manager. Simply go to Sketch > Include Library > Manage Libraries.... In the search box, type "BLEPeripheral", select it, and click "Install."
Alternatively, the library can be installed by downloading the latest version from the GitHub repository. Follow along with our Installing an Arduino Library tutorial for help installing the library via this method.
