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

[Beldramma]

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 Simonr, is it normal that i can see my device with NRF COnnect but not with the Bluetooth Common Settings ? Is there something missing in my code ?

That depends on what kind of device is advertising. The Bluetooth settings will be able to find some advertising devices, like HID devices, headphones, heart rate measurers, etc. So it depends on what your device advertises as, while the nRFConnect app has no filter by default, and will show any device advertising over BLE.

Best regards,
