Hi all,
I have a working Wemos/Lolin D1 Mini running WiFiTerm (discussed here Remote terminal/monitor for ESP8266 & ESP32 - Libraries - Arduino Forum ).
I can send commands to it from any browser and control different local actions via a command line interface :
#include <ESP8266WiFi.h>
const char* ssid = "";
const char* password = "";
#include "WiFiTerm.h"
ESP8266WebServer server(80);
void setup()
{
pinMode(D1, OUTPUT);
Serial.begin(115200);
Serial.print("\nConnecting to WIFI");
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print('.');
}
Serial.println("connected");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
server.begin();
Serial.println("webServer started");
term.begin(server);
Serial.println("term started");
}
void loop()
{
server.handleClient();
term.handleClient();
if (term.available()) {
incoming = term.readString();
incoming.toUpperCase();
term.println(incoming);
uint8_t i = incoming.indexOf(' ');
uint8_t j = incoming.indexOf(' ', i + 1);
cmd = incoming.substring(0, i);
p1 = incoming.substring(i + 1, j).toInt();
p2 = incoming.substring(j + 1).toInt();
//term.println(cmd);
//term.println(p1);
//term.println(p2);
if (cmd == "TEST")
{
digitalWrite(D1, 1);
}
if (cmd == "ON") // Turn on lamp
{
// send HTML request to Sonoff S20 slave esp8266
}
}
}
What I could need som help with is how to execute a HTML request from this sketch to another ESP (which has a static IP address on my LAN). That would be a wifi controlled power outlet like this Reprogram Sonoff Smart Switch Web Server | Random Nerd Tutorials.
I can see in the sonoff sketch that a web page like this will be provided :
"
SONOFF Web Server
<a href="on">ON <a href="off">OFF
";How can I send a HTTP "on" (or "off") command from the master to the slave ? I only need one way communication, the master can just throw away any web page element reply updates from the slave.
Thanks.
