Is it possible to have a point-to-point connection over Wi-Fi, similar to how an RF Module would work. No connections involved, just sending or receiving data packets to all nearby networks. I am trying to do so using some esp8266-01s modules, no encryption/handshakes needed (UDP?). Something to do with AP set broadcast messages? I am doing all this with no Wi-Fi Networks nearby, other than an esp8266 AP.

p.s. I am not looking to embed the data in the SSID's. (Unless that is the only option)

There's no no-handshake mode in Wifi: it's truly a network protocol.

You can build ad-hoc networks, but that's it. It might totally suffice, though! You can find a few github repos when you search for "esp8266 ad hoc", so I guess people have already done that.

  • \$\begingroup\$ this wont work due to the device connection limitation of the esp8266. I am looking for this ptp connection so i can have "infinite" clients. (Provided my RX Buffer is large enough) \$\endgroup\$

    \$\begingroup\$ bad luck, being a network, not a ptp, protocol is a limitation of IEEE802.11. You might have picked the wrong type of wireless interface hardware! \$\endgroup\$

  • \$\begingroup\$ Specifically picked this hardware because it is the cheapest MCU that runs MicroPython, (lol) and has wireless capability. I will probably go in the direction of a chained, or mesh network however, which can allow for hundreds of connections. Just wanted to exhaust all options before delving into programming for this topology. \$\endgroup\$

    \$\begingroup\$ Honest remark: if going for something like meshed IoT, IEEE802.11 (wifi) might really not be the kind of thing that makes your life easier! Zigbee (IEEE802.15.4) might be simpler, and more power-efficient, and it's designed with mesh networking right from the start. But you're right, if you just want any wireless interface, the ESP8266 is hard to beat. If you want to have zigbee, consider one of these, I guess :) \$\endgroup\$
