nrf51422 + HID/Consumer control

[Laszlo]

Dear All,

I am sorry but I have to ask this question here, I searched and red trough the forum, tried the suggestions, nothing works. Basically I want to have a HID device with keyboard + consumer control buttons(volume up/down), I have the nrf51 dev board and work with the SDK10. I already added the report nr.2 to the TLC with the consumer control device to the report map, followed and merged the changes from this post: Modify ble_app_hids_keyboard to be able to send Volumn_up/down keys Although the device is shown always as a joystick and not a keyboard, and the consumer control buttons do not work at all. I am strugling with this for a few days now, if anybody has a working demo or ideas please share it. Maybe changes between SDK9 vs 10 with the ble_hids_inp_rep_send ?

Regards, Laszlo

IMPORTANT: send the key release for the consumer control buttons!

The report map with the merged consumer control is: static uint8_t report_map_data[] = { 0x05, 0x01, // Usage Page (Generic Desktop) 0x09, 0x06, // Usage (Keyboard) 0xA1, 0x01, // Collection (Application) 0x85, 0x01, // Report Id (1)
