But after trying, it seemed just broadcasting beacon frames didn't work. OR, anybody can tell me what kinds of fr...

I can't understand ...

The CSI is extracted from received packet. First,thank you for your reply! I think that's exactly the key of my question. Now, I think i'd better receive CSI in the softAP, and use another chip as station to connect to this AP. In this way, I can send UDP data from my station to my softAP, which ma...
