I have an Arduino with a USB Host shield and a USB Bluetooth dongle connected.
This is working to the Wiimote using HCI and L2CAP stack I wrote, this successfully sends and receives reports from the Wiimote.
For connection I currently use outgoing to the Wiimote based on its bluetooth address and have to press the 1 and 2 buttons. This is fine, but I would like to understand the mode where the Wiimote will make an incoming connection after "pairing". Does anyone know how the bluetooth address of the host is set in the wiimote and this feature is enabled ? I do the same on the PS3 controller, but there the bluetooth address is set be special HID report on USB.
