Get Antenna Configuration (61h)
The Get Antenna Configuration command returns the current antenna configuration
including which antennas are set to transmit and receive, and which ports have antennas
attached.
Reliable antenna detection requires that an attached antenna pass at least a small
amount of DC current. Many antennas do not pass DC current. Due to such antennas an
indication that a port is terminated is always accurate, but an indication that a port is not
terminated may not be accurate.
The format of the command is:
The reply is formatted similar to the Set Antenna Port command. Data byte 01 returns
the current TX antenna, and data byte 02 returns the current RX antenna. The default,
and currently only, antenna configuration is TX on port #1 and RX on port #1.
The Get Antenna Configuration command also includes an option that also returns
information on which port(s) the antenna is connected.
For example, a command is sent:
The response returns the ports for TX and RX and also detects whether an antenna is
connected to the port:
