/**
|
|
* Parse all incoming BLE payloads to see if it is a Mopeka BLE advertisement.
|
|
* Currently this supports the following products:
|
|
*
|
|
* - Mopeka Std Check - uses the chip CC2540 by Texas Instruments (TI)
|
|
* - Mopeka Pro Check - uses the chip NRF52 by Nordic
|
|
*
|
|
* If the sync button is pressed, report the MAC so a user can add this as a sensor. Or if user has configured
|
|
* `show_sensors_without_sync_` than report all visible sensors.
|
|
* Three points are used to identify a sensor:
|
|
*
|
|
* - Bluetooth service uuid
|
|
* - Bluetooth manufacturer id
|
|
* - Bluetooth data frame size
