- Tue Aug 02, 2016 11:20 am #51957 I would like to connect two ESP among themselves. Press the button on the first ESP, the relay closes in the second ESP. Relay closes and signal about this comes back to the first ESP. LED lights on the first ESP.
Easy handshaking. I am sure that relay is working. Without WEB, NET or Arduino only two ESP speak between themselves.

- Wed Aug 03, 2016 7:31 am #52019 It sounds like what you need is ESP-Now. There is an issue open for that. It should be possible to use it already with the SDK calls directly, but I've not been able to get it to work yet.

- Fri Aug 05, 2016 2:01 am #52176 FWIW I've put the ESP-Now code I've been trying here. That probably does what you need if you just want two ESPs talking together.

I would just click controlled relays. Like "Blink", including feedback control.
