No. WiFi is a network connection and not a serial channel. So you have to open a connection on the network to send a data stream.In this case WiFi is probably not the best choice. Provide more information about the needs you have on that communication (speed, distance, reliability, obstacles, etc.), maybe we can suggest alternatives.
Open space, around 100-200m, no obstacles (maybe some trees), as reliable as possible. Use of battery. I need an inexpensive solution because in the future I will need more nodes.
Thank you
