Hi Naven,

I ran some test by my side, I used Android 9 and Samsung S9, the HID device example. I enabled the Privacy, as you did.

/* SMP Data */
gapPairingParameters_t gPairingParameters = {
    .withBonding = gAppUseBonding_d,
    .securityModeAndLevel = gSecurityMode_1_Level_3_c, 
    .maxEncryptionKeySize = mcEncryptionKeySize_c,
    .localIoCapabilities = gIoDisplayOnly_c,
    .oobAvailable = FALSE,
    .centralKeys = (gapSmpKeyFlags_t) (gLtk_c | gIrk_c),
    .peripheralKeys = (gapSmpKeyFlags_t) (gLtk_c | gIrk_c),
    .leSecureConnectionSupported = TRUE,
    .useKeypressNotifications = FALSE,
};
‍‍‍‍‍‍‍‍‍‍‍‍

/*! Enable/disable use of bonding capability */
#define gAppUseBonding_d   1

/*! Enable/disable use of pairing procedure */
#define gAppUsePairing_d   1

/*! Enable/disable use of privacy */
#define gAppUsePrivacy_d   1‍‍‍‍‍‍‍‍

What is the example that you are working on?

Regards,

Mario
