Pair Device with Legacy Connection OOB preshared key, using Android NRF connect

Hi,

I am working on NRF52832-based board, with SDK 15.2.

My BLE device is protected with Legacy Connection OOB preshared key.

I would like to use Android NRF Connect app to pair with my device, filling my OOB key.

I can be in pairing mode and fill my key in NRF Connect Desktop, but not with NRF Connect app.

I don't find any button to do that. There is only a button to bond, so I have added the bonding mode in my application, but I haven't succeeded to bond also.

DO you know how I can pair with my security parameters ? If I can do it only through bonding mode, can you help me resolve my problem ?

I have already checked these others subjects, but they haven't succeeded too :

  • Hi daviddedwin,

    I thought that the Android OOB was accessible only over NFC.  I also suspect that the Android OOB API is a private API in Android which complicates things a bit (not 100% sure but this was what I remember).
    Adding NFC is a possible solution, will that work for you ?

    Pairing mode with OOB without NFC works with NRF Connect Desktop, so  I am not sure that it is the problem.

    When i did the researches to choose the security process ( Just Works, OOB, Passkey), it seemed to me that we can implement OOB without NFC.

    By the way, the board is already made, we cannot add NFC inside.
