Field Documentation

unsigned int PacketGroupHandler::groupCode

The group code for this packet group. This number must be unique. The maximum number of packet groups is defined by WL_MAX_PACKET_GROUPS.

void(* PacketGroupHandler::handle_receive)(char type, int source, unsigned char *packet, int length)

Called when we receive a packet from this group. Parameters: type  the packet type source  the 16-bit address of the XBee this packet was sent from packet  the packet received length  the length of the packet

void(* PacketGroupHandler::handle_response)(int frame, int received)

Called when a transmit status packet is received from the XBee where the first four bits of the frame are the group code. Parameters: frame  the last four bits of the frame received  is true if we received an ack, 0 if we did not.

void(* PacketGroupHandler::timeout_handler)(void)

Called every half second (not in interrupt, but in wl_do).

void(* PacketGroupHandler::unregister)(void)

Called for any cleanup when the network is turned off.
