message is only sent to transceiver host if the proper transceiver configuration register flag is set
(RAM bank register sniffFlagsMask, flag BROADCASTIN_bm, see section 7.3).

Payload
Up to 20 bytes of data at 50kbit/sec, 72 bytes of data at 100kbit/sec
BcastUART2TrxBufferDone
Event message sent from transceiver to host after the UART transmit buffer is cleared and its
corresponding data is transferred in RF packet buffers, ready to be transmitted out. This marker is
always sent at the beginning of a broadcast, even if the UART transmit buffer is clear (only if
configuration register in RAM bank enableNotificationFlagsMask, flag
ENDUARTTRANSFERTOTXBUFFER_bm, is set; see section 7.3 for details).

RXBcastInSnifferAirDataPacket
Event message from a node (exclusively) transceiver to host, when it receives a sniffed packet
transmitted from another node towards the network gateway which contains an air command reply of
any kind (i.e. an air command reply sent back by a node after having received an air command sent by
a gateway, the latter having sent it via command TXAirCmdWrapper). This message is only sent to
transceiver host if the proper transceiver configuration register flag is set (RAM bank register
sniffFlagsMask, flag BROADCASTIN_bm, see section 7.3). Also note that the entirety of the raw
wrapped air command answer, including the sender node address bytes (if applicable), can be found
within the payload of this message.

RXBcastOutSnifferAirCmd
Event message from a node (exclusively) transceiver to host, when it receives a sniffed packet
transmitted from a gateway towards another node which contains an air command of any kind (sent
via TXAirCmdWrapper). This message is only sent to transceiver host if the proper transceiver
configuration register flag is set (RAM bank register sniffFlagsMask, flag
BROADCASTOUT_AIR_bm, see section 7.3). Also note that the entirety of the raw wrapped air
command, including the requested node address bytes (if applicable, and possibly for multiple nodes),
can be found within the payload of this message. Note that a supplementary parameter (Phase In
Count) is provided in this message in order for the recipient to know how many MAC addresses
