BLEHIDGamepad::BLEHIDGamepad

Description
Constructs a BLEHIDGamepad object.

Syntax
BLEHIDGamepad(void);

Parameters
NA

Returns
NA

Example Code
Example: BLEHIDGamepad
(https://github.com/ambiot/ambd_arduino/blob/dev/Arduino_package/hardware/libraries/BLE/examples/BLEHIDGamepad/BLEHIDGamepad.ino)

Notes and Warnings
By default, the BLEHIDGamepad class assumes the HID report descriptor implements a gamepad device with 16 buttons, 6 16-bit axes and an 8-direction hat switch. This class will not work if a different gamepad report descriptor is implemented. “BLEHIDGamepad.h” must be included to use the class function.

BLEHIDGamepad::setReportID

Description
Set HID report ID for the HID Gamepad.

Syntax
void setReportID(uint8_t reportID);

Parameters
reportID: The report ID for the gamepad device, corresponding to the HID report descriptor.

Returns
NA

Example Code
Example: BLEHIDGamepad
(https://github.com/ambiot/ambd_arduino/blob/dev/Arduino_package/hardware/libraries/BLE/examples/BLEHIDGamepad/BLEHIDGamepad.ino)

Notes and Warnings
HID report ID should start at 1. Some systems may consider a report ID of 0 as invalid. “BLEHIDGamepad.h” must be included to use the class function.
