Hi all, I hope I am posting in the right place.
I have an ESP32VROOM dev board which I'm using as an IR sender/receiver (also is used on an ESP8266 nodemcu board)
My main problem is the ever changing IP address of the board, whether due to a power cut or simply another devices IP seems to force it to change, I really need the IP address to be static.
I have tried numerous times to make the IP static, but have failed every step of the way, I need some guidance please, what to remove and what to keep?, thanks.
Here's my working code;
#include <Arduino.h>
#if defined(ESP8266)
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
#endif // ESP8266
#if defined(ESP32)
#include <WiFi.h>
#include <WebServer.h>
#include <ESPmDNS.h>
#endif // ESP32
#include <IRremoteESP8266.h>
#include <IRsend.h>
#include <WiFiClient.h>
const char* kSsid = "my_network";
const char* kPassword = "my_password";
MDNSResponder mdns;
#if defined(ESP8266)
ESP8266WebServer server(80);
#undef HOSTNAME
#define HOSTNAME "esp8266"
#endif // ESP8266
#if defined(ESP32)
WebServer server(80);
#undef HOSTNAME
#define HOSTNAME "esp32"
#endif // ESP32
const uint16_t kIrLed = 14; // ESP GPIO pin to use. Recommended: 14 (D2).
IRsend irsend(kIrLed); // Set the GPIO to be used to sending the message.
void handleRoot() {
server.send(200, "text/html",
"<html>" \
"<head><title>Command sent</title></head>" \
"<body>" \
// more content . . . .
"</body>" \
"</html>");
}
void handleIr() {
for (uint8_t i = 0; i < server.args(); i++) {
if (server.argName(i) == "code") {
uint32_t code = strtoul(server.arg(i).c_str(), NULL, 10);
#if SEND_NEC
irsend.sendNEC(code, 32);
#endif // SEND_NEC
}
}
handleRoot();
}
void handleNotFound() {
String message = "File Not Found\n\n";
message += "URI: ";
message += server.uri();
message += "\nMethod: ";
message += (server.method() == HTTP_GET)?"GET":"POST";
message += "\nArguments: ";
message += server.args();
message += "\n";
for (uint8_t i = 0; i < server.args(); i++)
message += " " + server.argName(i) + ": " + server.arg(i) + "\n";
server.send(404, "text/plain", message);
}
void setup(void) {
irsend.begin();
Serial.begin(115200);
WiFi.begin(kSsid, kPassword);
Serial.println("");
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to ");
Serial.println(kSsid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP().toString());
#if defined(ESP8266)
if (mdns.begin(HOSTNAME, WiFi.localIP())) {
#else // ESP8266
if (mdns.begin(HOSTNAME)) {
#endif // ESP8266
Serial.println("MDNS responder started");
}
server.on("/", handleRoot);
server.on("/ir", handleIr);
server.on("/inline", [](){
server.send(200, "text/plain", "this works as well");
});
server.onNotFound(handleNotFound);
server.begin();
Serial.println("HTTP server started");
}
void loop(void) {
server.handleClient();
}
