+     * The following method (startAirPodsScanner) creates a bluetoth LE scanner.
+     * This scanner receives all beacons from nearby BLE devices (not just your devices!) so we need to do 3 things:
+     * - Check that the beacon comes from something that looks like a pair of AirPods
+     * - Make sure that it is YOUR pair of AirPods
+     * - Decode the beacon to get the status
+     *
+     * On a normal OS, we would use the bluetooth address of the device to filter out beacons from other devices.
+     * UNFORTUNATELY, someone at google was so concerned about privacy (yea, as if they give a shit) that he decided it was a good idea to not allow access to the bluetooth address of incoming BLE beacons. As a result, we have no reliable way to make sure that the beacon comes from YOUR airpods and not the guy sitting next to you on the bus.
+     * What we did to workaround this issue is this:
+     * - When a beacon arrives that looks like a pair of AirPods, look at the other beacons received in the last 10 seconds and get the strongest one
+     * - If the strongest beacon's fake address is the same as this, use this beacon; otherwise use the strongest beacon
+     * - Decode...
+     *
+     * Decoding the beacon:
+     * This was done through reverse engineering. Hopefully it's correct.
+     * - The beacon coming from a pair of AirPods contains a manufacturer specific data field n°76 of 27 bytes
+     * - We convert this data to a hexadecimal string
+     * - The 12th and 13th characters in the string represent the charge of the left and right pods. Under unknown circumstances, they are right and left instead (see isFlipped). Values between 0 and 10 are battery 0-100%; Value 15 means it's disconnected
+     * - The 15th character in the string represents the charge of the case. Values between 0 and 10 are battery 0-100%; Value 15 means it's disconnected
+     * - The 14th character in the string represents the "in charge" status. Bit 0 (LSB) is the left pod; Bit 1 is the right pod; Bit 2 is the case. Bit 3 might be case open/closed but I'm not sure and it's not used
+     *
+     * After decoding a beacon, the status is written to leftStatus, rightStatus, caseStatus, chargeL, chargeR, chargeCase so that the NotificationThread can use the information
