Add support for AirPods 4 ANC

[colour93]

I'm not sure if these are the only logs needed. I tried switching ANC on and off after the logs start recording.

Nvm, i read this wrong. There are 2 different AirPods Gen4 Models.

I may not be expressing myself accurately because I'm using a translator. I hope to provide logs to help you identify AirPods 4, but I'm not sure if my method of obtaining the logs is correct. Thank you very much for your project.

The log was correct, I just had some trouble identifiying your AirPods because there are so many other devices in range.

I think this is yours then:

2024-09-23T03:07:50.997Z  I/CAP:Pod:Factory: Pod created: UnknownAppleDevice(identifier=Id(id=5da27927-d5da-4813-b863-cfec6949537d), seenLastAt=2024-09-23T03:07:50.994553Z, seenFirstAt=2024-09-23T03:07:34.439609Z, seenCounter=3, scanResult=BleScanResult(-75, 4C:FD:8F:EC:77:FD, 1505818804198473, 76: 07 19 01 1B 20 0B 9A 8F 10 00 04 43 DF EC 1D D3 F1 C3 F4 A1 9B 29 26 B9 E7 3A A0, proximityMessage=ProximityPairing.Message(type=7, length=25, data=01 1B 20 0B 9A 8F 10 00 04 43 DF EC 1D D3 F1 C3 F4 A1 9B 29 26 B9 E7 3A A0), reliability=0.5524, rssiAverage=-73)

that would make the identifier 1B 20

So based on your logs and the logs from #225.

• AirPods 4 (no-ANC) 0x1920
• AirPods 4 (with ANC) 0x1B20

I will use the same decoding mechanism as for AirPods 3 and include initial support in the next update. Let me know if anything looks wrong.
