Lit when the SoftDevice is enabled.

Building and running

This sample can be found under samples/bluetooth/hello_softdevice/ in the Bare Metal folder structure.

For details on how to create, configure, and program a sample, see Getting Started with the samples.

Testing

You can test this sample by performing the following steps:

1. Compile and program the application.

2. Observe that the Hello SoftDevice sample started message is printed.

3. Observe that the SoftDevice enabled message is printed and LED 2 is ON.

4. Observe that the Bluetooth enabled message is printed.

5. Observe that the SoftDevice disabled message is printed and LED 2 is OFF.

6. Observe that the Bye message is printed.
