This can +be done when the module is loaded (specifying the name of the network interface +as a paramter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after +loading using an ioctl call. See the ozappif.h file and the ioctls +OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING. + +The devices connect to the host use Wi-Fi Direct so a network card that supports +Wi-Fi direct is required. A recent version (0.8.x or later) version of the +wpa_supplicant can be used to setup the network interface to create a persistent +autonomous group (for older pre-WFD peripherals) or put in a listen state to +allow group negotiation to occur for more recent devices that support WFD. + +The protocol used over the network does not directly mimic the USB bus +transactions as this would be rather busy and inefficient. Instead the chapter 9 +requests are converted into a request/response pair of messages. (See +ozprotocol.h for data structures used in the protocol). |
