Hi.

Have you looked at the documentation for this example here?

At the bottom of the documentation you can find a testing procedure, which is as following:

Test the Power Profiling Application with nRF Connect by performing the following steps:

Compile and program the application.
Start nRF Connect on the computer.
Start device discovery and verify that the device is not advertising.
Push Button 1 on the board. Observe that the application is advertising in connectable mode.
Connect to the device.
Click the settings button for the device in nRF Connect, select "Update Connection", and set the connection interval value to the same as APP_CFG_CONNECTION_INTERVAL.
Observe that the services are shown in the connected device and that you can start receiving values by clicking the 'Play' button.
After APP_CFG_CHAR_NOTIF_TIMEOUT, nRF Connect will lose connection with the chip because it enters System Off mode.
Verify that the size of the characteristic value received in all the notifications was equal to APP_CFG_CHAR_LEN.
Clear the list of discovered devices and do a new scan. Verify that the device is not advertising.
Push Button 2 on the board. Observe the application is advertising in non-connectable mode (the Advertising type field should be Non-Connectable).
Verify that the number of bytes in the Manufacturer Specific Data in Advertising data is APP_CFG_ADV_DATA_LEN - 5.
After APP_CFG_NON_CONN_ADV_TIMEOUT, clear the list of 'Discovered Devices'. Verify that the device is not advertising.

At point 4) When the board is advertising you should see that LED1 is blinking, you can read about the different board indications and states here.

Best regards.
