5.1.5. Set operational bandwidth
Set the bandwidth for sending and receiving data packets, and set the guard interval (Guard Interval) for
transmitting MCS packets. If no parameters are provided, the default setting is 20MHz bandwidth and is
transmitted using a long guard interval (long GI).
iwpriv mp_bandwidth 40M=40m, shortGI=sgi
40m: Set bandwidth, 1=40M bandwidth mode, 0=20M bandwidth mode
sgi: Set the mode of GI, 1=Short GI, 0=long GI
5.1.6. Set Tx power
Set the transmit power of paths A and B. If no parameters are provided, use the parameters preset in
Flash.
iwpriv mp_txpower patha=x,pathb=y
x: The transmit power of path A.
y: The transmit power of path B.
5.1.7. Set antenna for Tx
Set the antenna to use when sending
iwpriv mp_ant_tx ant
ant: Set the antenna used for transmission, a=antenna A，b=antenna B，ab=antenna A and B。
5.1.8. Set antenna for Rx
Set the antenna to be used for reception
iwpriv mp_ant_rx ant
ant: Set the antenna to be used for reception, a=antenna A，b=antenna B，ab=antenna A 和 B。
5.1.9. Start air Rx mode
This command is used for wireless reception testing. Use the Start command to start the collection, use
the stop command to stop the count, and display the statistics of the correct and error messages. Use
the phy command to display the number of RF physical layer receive packets, CRC errors, and failed
alarms.
iwpriv mp_arx start/stop/phy
start: Start collecting.
stop: Stop counting and display statistics.
phy: shows the number of RF physical layer receive packets, CRC errors and failure alarms
5.1.10. Start continuous Tx mode
This command is used for continuous packet testing. Use the time command to set the time for sending.
Use the count command to set the number of packets to be sent. If neither time nor count is set, the
continuous packet sending mode will be started. If the background mode is not set, the input of any
