API OPERATION

API RECEIVE PACKET
By default, the source MAC is not included in the received data string sent to the OEM Host. For applications where
multiple radios are sending data, it may be necessary to determine the origin of a specific data packet. When API
Receive Packet is enabled, all packets received by the transceiver will include the MAC address of the source radio
as well as an RSSI indicator which can be used to determine the link quality between the two.
API Receive Packet is enabled when bit-0 of the API Control (Address 0xC1) byte is enabled. Upon receiving a RF
packet, the radio sends its OEM Host the data as shown in Figure 2 below.

API TRANSMIT PACKET
API Transmit Packet is a powerful API Mode that allows the OEM Host to send data to a single or multiple (via
Broadcast) transceivers on a packet-by-packet basis. This can be useful for many applications; including polling
networks and mesh networks.
API Transmit Packet is enabled when bit-1 of the API Control (address 0xC1) byte is enabled. The OEM should
pre-pend each packet of data with the following header information.

Setting the Destination Address to 0xFF 0xFF 0xFF will broadcast the packet to all available
transceivers in the network.
