The special buttons have no example ?

Hi, I was wondering if you could make an example in which the "pressSpecialButton" function is explained. I need this function to open the browser on a pc, thanks!

Currently supported special buttons are as follows buttons:

• start
• select
• menu
• home
• back
• volume up
• volume down
• volume mute

I think it's up to the target host OS to implement support and functions (or possible an app to hook the special buttons action).

The above should be found in the HID Usage Tables - https://www.usb.org/sites/default/files/hut1_3_0.pdf ie: Volume Increment - Usage ID: 0xE9 - Consumer Page: 0x0C

Thou I have not yet tested any of the special buttons myself, might give it a try in the future and report back.

I would start with checking that the BLE Client (ESP32) is paired with the BLE Server (OS Host). Then use something like the BLE Scanner and monitor things are working and reporting as expected.

I use T-vK/ESP32-BLE-Keyboard to control the volume normally.

As above Those special keys only work in Android ESP32-BLE-Keyboard will do volume control in Windows
