Ask: Direct sending and receiving data trought WiFi

#1
It takes a long time to connect to the server. I would like to be able to send data packets directly without connecting to the wifi server. I would create a mesh wifi. (similar https://reticulum.network/, tox https://github.com/TokTok/c-toxcore etc) I would like in root/administrator mode to send and receive packets directly. How to do this in linux? How to send a message when the wifi devices only pass each other for a few or a few tens of seconds for example.

There was a standard called Wi-Fi Direct for such a use case. I remember evaluating it for a automotive project (where cars would pass object only for a short time). Maybe it’s fits your use case. https://en.m.wikipedia.org/wiki/Wi-Fi_Direct

wifi direct have transmiter and receiver too ;) In my opinion sending message like walkie-talkie radio protocol is different. (for example https://github.com/ntoivola/uvk5-chirp-driver-nunu )

Sounds more like bluetooth.

I took that to mean pretty close.

RFID has some of the significant properties you are looking for. I don't know if it has all of them because I've just about exhausted all my knowledge of RFID and don't know any details of the actual problem you are trying to solve. But RFID is deployed at scale and "everywhere." Probably because the technology doesn't depend on protocols developed for other uses (e.g. IP). Good luck.
