By checking return values I mean by checking return codes with the macro APP_ERROR_CHECK. Please check out this debug "guide" for some pointers on how to debug a project.

Already confirmed that I have set the correct #defines in the sdk_config. Not sure what you mean by setting return values?

Have you set the BLE_LBS_ENABLED (BLE_LBS_C_ENABLED for the client) in the sdk_config.h header file when adding the BLE_LBS service? It sounds very strange that you're not able to see anything useful in your debug log. Can you try setting some returns so you can see if any return values are triggered when the buttons are pressed.

Yes I have used the NFC example successfully already. My application only requires an extra LED Button on the peripheral device, so I added an external button circuit on a spare GPIO pin (pulled up as the other buttons are). I believe I've added this pin correctly to the board support and the functionality to the bsp_event_handler. On the central device, I haven't changed anything with the buttons or pins. However, on both devices, with the addition of the ble_lbs service in the example, none of the buttons on either device are triggering any events or any action at all really, which I find strange.

Hi Sam

Can you confirm that you've used the experimental ble_nfc_pairing_reference_c and ble_nfc_pairing_reference example projects? Please note that some buttons are already used in this example to switch between pairing modes.

Peripheral:

You can use buttons to switch between pairing modes:

Press Button 1 to terminate the current connection.
Press Button 2 to switch into LE Secure Connections OOB pairing.
Press Button 3 to switch into Legacy OOB pairing.
Press Button 4 to switch into Legacy Just Works pairing.

Central:

Use the buttons to control the device:

Press Button 4 to initialize pairing.
Press Button 3 when connected to disconnect from a device.
Press Button 3 when disconnected to erase bonding.

The BLE Blinky application also uses Button one in order to turn on LED 3 on the central board, so you will have to make sure that Button 1 is only used for one operation so they don't conflict with one another. Lastly, the BLE Blinky application will only work when the two devices are connected, so you will have to make sure they are connected when trying out this.

Best regards,

Simon
