   CSI capture condition #342 has the same problem, but is in CSI capture condition.
   IQ sample capture follows the Quick start

I power on the SDR board and set computer static IP with 192.168.10.1. Open a terminal on the computer, and then in the terminal:
ssh root@192.168.10.122
cd openwifi
./wgd.sh
./monitor_ch.sh sdr0 11
insmod side_ch.ko iq_len_init=4095
./side_ch_ctl wh3h01
./side_ch_ctl wh11d4094
./side_ch_ctl g

The output I got:
root@analog:/openwifi# ./side_ch_ctl wh3h01

It seems like no IQ is captured. Could you please help?

Hi @jiang910622, are you transmitting any frames? The IQ capture is triggered by the start of the station its own transmission.
