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 )

I would think this is going to have to be something that comes from the Host OS (Win or Mac) - so not really anything to do with Nordic?

So might be better asking on  general BT/BLE forums, and/or on Win/Mac developer forums ... ?

Yeh, maybe it's not Nordic problem, thanks for the remind and advice, we will try to ask on the developer forums~

I guess the other thing would be too look into the HID specs to see if they have generic definitions for your "gestures",  which the Host OS would interpret suitably - rather than you having to mimic host-specific keys ...
