I need to achieve connectionless, low-latency point-to-point wireless transmission of a video signal. I cannot rely on a traditional wifi infrastructure with Access Point to do this. Therefore I want to directly inject 802.11 frames at the sender, and capture them at the receiver.
I am successfully using the RTL8720DN in wifi promiscuous mode with the Arduino SDK (3.0.8) to receive 802.11 frames. Now I need to be able to transmit those frames as well. Unfortunately in the wifi API I couldn’t find any explicit function to do this.
Hence my simple question: how can I inject 802.11 frames with the RTL8720DN ?
Thanks for help !
