the HID key “codes" are defined in the HID Usage Tables e.g. http://www.usb.org/developers/devclass_docs/Hut1_12v2.pdf On 07 Apr 2014, at 13:26, Aaron Xu <overheat1984@gmail.com> wrote:
Hi Matthias,
Thanks a lot! This is very smart, and I am bright ：）
In addition, where is the key number which is keyboard's code. I saw some key number in a example code, for example 0x08 means "e", 0x0b means "h", 0x28 means "return". But I can't find "volume up" in that BLE keyboard example.
Where can I get the HID key number for iOS?

just a shot in the dark. iOS HID driver accepts volume up events and also supports HID over LE as far as I know. So, if you implement an LE HID Keyboard and send the volume up, you should be fine.

Hi,
Is there any function to control iPhone's volume + button through my BLE device?
I want to develop a gadget, which control iPhone to take photo. I think it will work if I open the Camera APP on iPhone and "press" the volume + button by my BLE device.
Any solution for this? Please let me know.
