Has anyone got the solution Kristin linked to work?

I'm using SDK v12.3, started with the HID example and that works, I can see the keystrokes in android. I updated hids_init() to match the github example code and replaced keys_send() calls with consumer_control_send, but so far I'm not having any luck getting the device to respond.

Edit: I've got it working now, it was something in the report map. Since all I want to do is control media, I updated to the report map in the main.c file that is attached to this thread and it's working.

From what I can see in USB HID Usage Tables on p. 56, vol +/- and play/pause has the following commands:

Volume up: 0x80
Volume down: 0x81
Play/pause: seems to be described in chapter 3.4.4 "Alternate Types"

Update 26.10.2016: This example on github shows how to transfer vol+/-, play/pause. The example is for an older SDK, but the HID part/HID coding will be the same with a newer SDK.
