HR with pairing over NFC

[ff]

Hi,

I am trying to get the experimental NFC example "HR with pairing over NFC" to work. I can read the tag correctly with an android phone : the NDEF message is correct and the chip starts to advertise. I confirm on the phone that i want to pair the devices and then... it fails and tells me that the authentification failed (incorrect PIN...) after ~10s

I tried both "Just Works" (which is completly open) and OOB configurations with different types of messages (LE/EP)

Did you manage to get the two devices paired ?

config : android 5.1.1, nRF52 (10036) with sd132.

Thank you for your help.

I believe the devices are paired, but the smart phone will disconnect, and on disconnect the nRF52 will not restart advertising.

If you just add some code to start advertising in the BLE_GAP_EVT_DISCONNECTED event in on_ble_evt() you should be able to connect, with for example nRF Toolbox.

Sorry for the late reply. It seems to me that you have gotten the example to work as it should. We don't have an example with the functionality you describe. The pairing is done with the android system. For an app to connect you automatically, I guess you would use NFC to open the app and send for example the device address to the app. Then the app can connect to device. I think this would be a nice example to have in our SDK, and taken this to the developers.
