*Note: Send Data Complete may report a failure though the packet arrived due to timing issues. It will never report
successful though unless the packet absolutely arrived.

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 byte is enabled. Upon receiving a RF packet, the radio
sends its OEM Host the data as shown in Figure 14 below.
