Hi Aaron 0x80 is the Keyboard Vol Up. It might be that you have to use F11 or F12 for the volume control. best matthias --- Dr. sc. Matthias Ringwald BlueKitchen GmbH, Zürich On 14 Apr 2014, at 16:30, Aaron Xu <overheat1984@gmail.com> wrote:

Hi,

I send "0x80" to iPhone(iOS 7.1) and expect volume up, but nothing happened. Other words can be display on the editer, like "hello".

Which Usage ID is the volume up for iOS device?

the HID key “codes" are defined in the HID Usage Tables e.g. http://www.usb.org/developers/devclass_docs/Hut1_12v2.pdf

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.
