Non-Multiplexer Options
For backward compatibility the following syntax(Option=0x00 and 0x01) is supported
when using only the physical module ports directly. For new development the Logical
Antenna Options syntax should be used.
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
antenna configuration is TX on port #1, and RX on port #2, except on the M5e-Compact
which only has 1 port so the M5e-Compact’s default 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:
