ble_nfc_pairing_reference example pairing problem

[enkavak]

Hello,

     I wish to use "ble_nfc_pairing_reference" example with nRF52832 IC and SDK15. I flashed the example into "nRF52 DK" board. When I enable the NFC and BLE on my phone and put it closer to the "nRF52 DK" board, a message pops up on my phone and says "hello". Nothing happens other than this message. No BLE pairing occurs.

     In addition, I would like to use this "ble_nfc_pairing_reference" example with "ble_app_uart" example. Is it possible? can I merge them easily? 

Can somebody help?

Have you deleted the bonds on the phone and device beforehand? 

Did you use the precompiled hex or did you build the example yourself?

[enkavak]

There are no bonds on my phone. all deleted

I both used the precompiled hex and build by myself. I got the same result.

[enkavak]

could you please share the hex file you flashed. I can try it out

[haakonsh]

sorry for the late reply. I used the ble_nfc_pairing_reference_pca10040_s132.hex found in nRF5_SDK_15.0\examples\ble_peripheral\experimental\ble_nfc_pairing_reference\hex

Have you tried another phone? Every phone i've tried prompts a "Do you want to pair with the bluetooth device" or similar message.

I erased and reflashed. Now, it is working.

Now, I need to add this functionality to  "ble_app_uart" example. Could you please help me with this issue?

[haakonsh]

The nRF device stores the pairing information in persistent storage thereby bonding to the phone and that is why you are not prompted by a pairing request. By erasing the flash you erase the bonds. 

To add this feature to another example you will need to find the differences between the two example in terms of included libraries and API calls and add them to the ble_app_uart example. 

[enkavak]

could you be more specific ?
