This is a lot of spaghetti....

The app is very... compartmentalised... many subsections which I'll need to look through lol
I do know that com.sonova.mobilesdk seems to handle scanning for HAs

Ugh, yet another BTC BTLE implementation...

Like many other companies, Sonova has opted to use a packet-response architecture despite using BTLE, which kind of defeats the purpose of BTLE in my opinion...

still better than BT-Classic tho lol

Regarding HA BLE Scanning

Sonova HAs are scanned in "scan mode 2" (aka: SCAN_MODE_LOW_LATENCY) - https://developer.android.com/reference/android/bluetooth/le/ScanSettings.Builder#setScanMode(int)

Java:

new ScanSettings.Builder().setScanMode(2).build();

They are filtered through manufacturer data:
https://developer.android.com/reference/android/bluetooth/le/ScanFilter.Builder#setManufacturerData(int, byte[], byte[])

Java:

new ScanFilter.Builder().setManufacturerData(642, new byte[0]).build()
