Hi, i'm currently working on a low power sensor device based on nrf52832. I want to transfer data only to bonded central devices. Priority is using static passkey, but my hardware can deal with NFC as well. I'm a little confused with all pairing options. Both methods work well separately: predefined PIN (6 ascii numbers) request with sd_ble_opt_set(...) function inside gap_params_init, and NFC pairing with authorisation key (7-16 hex bytes) and whitelist stuff as shown in experimental NFC bonding examples. But when i try to combine them, it all goes crazy. What i'm looking for is preserve PIN authentification, but in case of smartphone with NFC support, perform pairing and bonding by a "touch" without entering digits. As far as i understand SEC_PARAM_OOB macros forces you to make a decision between the two inside peer_manager_init(...). It's also unclear to me that i can use BLE_GAP_AUTH_KEY_TYPE_PASSKEY instead of BLE_GAP_AUTH_KEY_TYPE_OOB when performing err_code = sd_ble_gap_auth_key_reply(...).
