Olá.
Não percebi muito bem a pergunta.
Mas se precisa de comunicação rápida entre várias ESP32 em estilo network, eu recomendo usar comunicação ESP-NOW.

Bom dia Sara
Estou em um projeto onde temos vários ESP32 como clientes rodando entre diversos APs, todos na mesma rede (SSID) porém estou encontrando muita falha em reconexão entre as antenas. Preciso que a reconexão seja menor que 1S, tem algum sistema rodando com reconexão abaixo deste temnpo? Teria exemplo de cmo codificou?
Obrigado.

Is there a way to connect to the strongest network after the existing connection has failed? Best would be to make the controller rescan the networks. Thanks for any hint!

In my experience, this does not necessarily pick the strongest signal. I have three in a cluster of greenhouses and two pick the strongest signal (-56) and the third picks the second (-67). It is handy in that I can move devices between my home and the nursery without reprogramming them.

Hello, Ibrahim!
I’m afraid that I still haven’t picked-up that project and tried-out the library. Thanks for reminding me about it — it’s now on my new-year to-do list. I’m embarrassed to say that the circuits are still on breadboards, but have been in use all of this time — on a fixed access point. When I deploy them properly, selection of the best AP will matter. It will be good to get these things deployed, finally!
Sorry I couldn’t give you a definitive answer at this time.
Regards,
Gerallt.

Hello Gerallt,

I hope you are doing well. I have the same issue as you, have you tried the WiFiMulti library?
If yes, have you achieve a reliable connection and what is your thoughts about the library?

Thanks.

Do you need to call the “run” method, in “loop” to get reconnected or will it happen during normal network activity?

Olá.
Não testei. Mas tratando-se de uma ESP32, sim, deverá funcionar.
Cumprimentos.

Este projeto pode também ser usado com o esp32-cam? Obrigado

Excellent!. Thanks for sharing!
I’m doing kind of similar work but saving my SSID/Pass sets, in a dynamic file on the ESP and then manually checking the power of each SSID!!
