How to make device HID compatible with Win & Mac

[AndrewJiajie]

We are developing a mouse with shortcut keys on Nordic, we want to make it compatible both on Win and Mac, but the shortcut key assignments are different between the 2 system. Is it possible that our mouse can know the connected system and send different keys accordingly?

(Actually as far as we know, the "Lofree mouse" already implemented that feature: www.lofree.co/.../maus-mouse )

looks like a genuine usecase, but I am not aware of any native BLE tricks to figure this out, I will try to do a bit more research on this on Monday to see if we can come out with some nice way to deal with this.

There does not seem to be a straight forward way to do this.

But apple IOS seems to be utilizing the characteristic, Manufacture String name (2A29) inside Device information service (180A).

You can start to see if different OS BLE variants have utilized this service. Do not see any other proper way to differentiate other than the one mentioned.
