Don't wake iOS device on "Skip Forward" and "Skip Back" HID Device

[Jordan Hardy]

Using the NRF SDK, I am developing a remote BLE HID device that is a music controller (Play/Pause, skip forward, back, volume up down). I am having an issue with iOS devices where if the Skip forward/back buttons are pressed while the iOS device is asleep (i.e screen off), the first press will wake the device, but not change track, and the second press will actually change track.

Is there any way around this as an HID device? I thought maybe removing 

HID_INFO_FLAG_REMOTE_WAKE_MSK

would help, but it doesn't seem to fix the problem. I have tested other Bluetooth music controllers, and this doesn't happen - the track changes without waking the iOS device. This problem is not present on Android.

Any ideas?

Thanks!

Hi,

It would be interesting to know the difference between your implementation and the other product where this works with iOS (perhaps it use a specific workaround/trick). Can you make a sniffer trace of both and upload here so that we can compare? Also, is it possible to build your project for a DK so that I can test on my side?
