Qt BLE : Bonding and ble security

  • Hi,

    I'm developing a Qt application that communicates with a BLE device. It works perfectly until I tried to add some security. When I turned on "Just Works" security mode, I was not able anymore to write in a characteristic (or read) from my Qt application.

    I compared the Bluetooth messages sent from Qt and from the android app nfr Connect and I see that automatically, the nrf Connect send a bonding request when it fails to write.
    Qt does not do this. That the only difference that makes the android app working but not my Qt app.

    I could not find anything about bonding in the API or security mode settings.
    Any idea ? Should I post it as a bug or am I missing something ?

    PS : I already saw this post but no reply...
