what is the usage page and usage code for adjusting the brightness on ios

[ziv]

to control IOS by HID, for example, the volume up and down is 0xE9 and 0xEA in consumer page(0x0C). what's the brightness down and up?

I have test Display Brightness( 0x46) in the alphanumeric display page(0x14), there's no effect. and Brightness( 0x10) the VESA Virtual Control Usage Page(0x82),there's no effect. Do modifier keys have effect? if it's, which keys are they? Does somebody know? if some guy make it work with the 0x14,0x46 or 0x82,0x10, could you tell me the way?

I bought a remote controller（BT3.0） that can adjust IOS's bright and volume. I want to implement its all functions on 51822(BLE).

The documentation for such extended keys supported by iOS is only available through the MFi program, so I'm afraid I can't really give a lot of information on this. I suggest that you evaluate the MFi documentation to see if there is any way to do this, and if not, get in touch with your MFi contact person.

OK. Thanks for your replies.

No problem, but I'd appreciate it if you could accept my reply as an answer, by pressing the button below it, to clear up this question. :-)

I wish other ble or ios developers would see it and perhaps give out a right answer.
