IQ sample capture - Side info count not incrementing

[remydemy]

Hello,
I'm trying to execute the IQ sample capture on my ANTSDR E310, but unfortunately the side info count is not increasing.
These are the commands I execute:

cd openwifi
./wgd.sh
./monitor_ch.sh sdr0 11
insmod side_ch.ko iq_len_init=8187
./sdrctl dev sdr0 set reg xpu 1 1 // This command is mentioned in iq.md to capture self TX signal, but I'm not quite sure when I should execute it
./side_ch_ctl g

The result I then get is:

loop 64 side info count 0
...

So the side info count remains at 0 and does not increase.
What could be the cause of that?

Best regards,
Emily

If you read our app note carefully, you should realize that you should not use 8187.
