    Based on https://developers.google.com/nearby/fast-pair/spec, the pairing is constructed by - * both BLE and BREDR connections. Example state transitions for Fast Pair 2, ie a pairing key is - * included in the request (note: timeouts and retries are governed by flags, may change): - * - * 

    - * {@code
- *   Connect GATT
- *     A) Success -> Handshake
- *     B) Failure (3s timeout) -> Retry 2x -> end
- *
- *   Handshake
- *     A) Generate a shared secret with the headset (either using anti-spoofing key or account key)
- *       1) Account key is used directly as the key
- *       2) Anti-spoofing key is used by combining out private key with the headset's public and
- *          sending our public to the headset to combine with their private to generate a shared
- *          key. Sending our public key to headset takes ~3s.
- *     B) Write an encrypted packet to the headset containing their BLE address for verification
- *        that both sides have the same key (headset decodes this packet and checks it against their
- *        own address) (~250ms).
- *     C) Receive a response from the headset containing their public address (~250ms).
- *
- *   Discovery (for devices < Oreo)
- *     A) Success -> Create Bond
- *     B) Failure (10s timeout) -> Sleep 1s, Retry 3x -> end
- *
- *   Connect to device
- *     A) If already bonded
- *       1) Attempt directly connecting to supported profiles (A2DP, etc)
- *         a) Success -> Write Account Key
- *         b) Failure (15s timeout, usually fails within a ~2s) -> Remove bond (~1s) -> Create bond
- *     B) If not already bonded
- *       1) Create bond
- *         a) Success -> Connect profile
- *         b) Failure (15s timeout) -> Retry 2x -> end
- *       2) Connect profile
- *         a) Success -> Write account key
- *         b) Failure -> Retry -> end
- *
- *   Write account key
- *     A) Callback that pairing succeeded
- *     B) Disconnect GATT
- *     C) Reconnect GATT for secure connection
- *     D) Write account key (~3s)
