uint8_t macSendPacket (TMessageComponent * node, TMACPacketType pkttype,
TMACAddress destaddr, uint16_t ackTimeout, uint8_t ackRetries, uint8_t msgNo, TTxMode
mode)
Sends a generic packet using the MAC layer.
Parameters:
node
pkttype
destaddr
ackTimeout
ackRetries
msgNo
mode
Return Values:
Always returns 1 in current revision.
This function is called to send a packet using the MAC layer. The MAC layer provides point-to-point
connectivity with other nodes in the network using a unique 32-bit address.
The local MAC message is configured based on the information passed to the function. Then, the
PHY is called to transmit the complete packet. When the PHY is done, macPacketMgrRxDone() is
called by the PHY to notify the MAC that the packet is sent. At that point, the packet engine will take
over and manage the rest of the MAC's responsibility regarding the packet. If the packet requires an
ACK; a timer is started, and automatic retransmissions will be attempted when the timer expires. If no
ACK is required or the ACK is received, the MAC will generate a packet sent event.
Valid pktType values:
The function is blocking and will maintain control of the processor until the packet transmission is
complete.
5.0.4 PHY LAYER MANAGER API
Detailed Description:
The PHY layer is responsible for sending and receiving packets using the radio. It is analogous to the
PHY layer in the OSI 7-layer protocol reference stack. It does not provide assured delivery. It can be
used directly by the application when a very simple protocol is being built or when the application has
legacy requirements that aren't filled by the higher protocol stack elements.
The current distribution contains a receiver-synchronized, 26-channel FHSS algorithm that can be
used in addition to a single-frequency DTS mode of operation.
