How to set the transmit rate and antenna number? #142

I saw the instruction in the FAQ 1, "echo 0x4214 | sudo tee \

/sys/kernel/debug/ieee80211/phy0/netdev:wlan0/stations/00:0f:34:9d:01:a0/rate_scale_table".
It says 0x4214 sets the transmit rate for the station above to 2 Mbps, using Antenna A, but when I user ./log_to_file to record the csi trace, I got 3x3x30 matrix. So the instruction does not set the transmitter antenna to only antenna A, am I do something wrong or I do not get the right point?

@lidongmeng Hi, did you solve the problem? Can you please share how to choose only one antenna? II can echo the rate, but all the rates that i try to echo end up in either 2x3x30 or 3x3x30 matrices
