ESP-NOW protocol made simple for quick & easy implementation.
IMPORTANT: esp-now protocol doesn't required wifi to be connected to a network, but it still need wifi to be turned on in order to work. If you are not using wifi, set the wifi mode to station and disconnect wifi. EspRC will work as long as wifi connection is being used. And don't let wifi to go to sleep.
WiFi.mode(WIFI_STA);
WiFi.disconnect();
Upload the following code onto 2 esp8266 devices, then open both serial terminals and start typing...
#include "MeshRC.h"
void setup() {
Serial.begin(921600);
MeshRC.begin(1);
MeshRC.on("message", []() {
String msg = MeshRC.getValue();
Serial.printf("received: %s \n", msg.c_str());
});
}
void loop() {
if (Serial.available()) {
MeshRC.send("message", Serial.readStringUntil('\n'));
}
