The gap between the first 26 subcarriers and the last 26 subcarriers (AEGHB-585) #166

image Use router (send) and esp32-s3 (receive). The amplitude is calculated from the collected data, and then the heat map is drawn. There is a very clear gap between the first 26 subcarriers and the last 26 subcarriers, which is like the data collected using two different devices. May I ask what the reason is?

You can try to check the bandwidth of the received packet to see if it is 40MHz.
