Has anyone built a hearing aid tracker?
My Phonak Audéo I90-Sphere hearing aids use BLE to communicate with their app (volume, program, battery level, etc.). They also use a classic BT connection for streaming.
I’d like to capture the BLE traffic and log the battery level, and maybe at some point use them for presence detection.
I have a BLE scanner on my phone, and I see what looks like a hello message listing a number of capabilities and their GUIDs, but none jumps out as battery level. I’m thinking of just logging everything I see from one of them for a while to see what the messages look like and maybe I’ll be able to pick out a pattern.

NRF Connect app is helpful for these “jobs”.
Nordic have been intimately involved in developing the BlueTooth standard and have excellent tools and documentation you may wish to access on their website.
Battery level is one of the standard profiles that should be easy to spot from the Nordic tools.
Log everything and like you said, spot the patterns.

Nordic apps don’t seem well suited to MacOs. Installer doesn’t handle dependanies, then when I get to the BLE tool it says I need to install a development kit, but that keeps leading me to hardware requirements.
I’m going to see how I make out with the Android version of the app.
Apple seems to have made certain that anything BlueTooth is firmly locked into their ecosystem with artificial limitations to prevent usage outside their carefully overpriced offerings.
You will be shocked when you get to the Android ecosystem - quite the opposite.
You cannot help feeling that Apple may have a touch of spite involved, forcing you to very expensive tooling, just to experiment with the technology.
