I am using the mesh network example given in the Arduino IDE hellomesh program.My target is to create mesh network for 3 or 4 ESP8266 modules should communicate with each other.
Does i need to dump the same program in all the nodes or there should be some other code for nodes.
#include <ESP8266WiFi.h>
#include <ESP8266WiFiMesh.h>
/* Create the mesh node object */
ESP8266WiFiMesh mesh_node = ESP8266WiFiMesh(ESP.getChipId(), manageRequest);
/**
* Callback for when other nodes send you data
*
* @request The string received from another node in the mesh
* @returns The string to send back to the other node
*/
String manageRequest(String request)
{
/* Print out received message */
Serial.print("received: ");
Serial.println(request);
/* return a string to send back */
return String("Hello world response.");
}
void setup()
{
Serial.begin(115200);
delay(10);
Serial.println();
Serial.println();
Serial.println("Setting up mesh node...");
/* Initialise the mesh node */
mesh_node.begin();
}
void loop()
{
/* Accept any incoming connections */
mesh_node.acceptRequest();
/* Scan for other nodes and send them a message */
mesh_node.attemptScan("Hello world request.");
delay(1000);
}
