[Feature Request] Extended Battery support, like charging?

[LeeNX]

Possible add GATT Battery Status (0x2A1A) and Battery Level State (0x2A1B)

On the Bluetooth SIG page, https://www.bluetooth.com/specifications/specs/battery-service/ there is a release for Battery Service 1.1

Which includes some items that might be worth adding, if we want the host to know if the gamepad is charging or other battery health/service properties. It's more a UX thing, but I can see the gamepad been charged, while in use.

This FR is mostly for UX, like I have seen on things like RetroPi, where the On-Screen-Display for battery level, which we do, but also if the device is been charged, with battery and lightning bolt displayed.

If we get a bunch of other features with the same update, that is just awesome, but I am not sure that anybody is really using the battery health or battery serial numbers stuff.

Well, releases from 7.3 now have the ability to set 0x2A1A info, and have it available in the OS

0x2A1B seems to just be the level we already have, so I ignored that one
I tested adding other battery characteristics, which work, though I think this one is enough to give/set all the info we need

Check new example for info

Okay to close?
