Hello i am new to NodeMCU (ESP8266) i am building a small program to connect with WIFI (with internet) and if internet is not available i want to process request over IP address.
I am using firebase as a database / server to fetch the status. And process command through a URL like http://192.168.1.223/on?pin=04 if internet is connected then no problem i can update firebase entry, but with same network (LAN) connection over wifi i want to process i need to have static IP. But the concern is i am not able to make this IP address static, and if i make it static then my NodeMCU is not able to connect with firebase.
Here is how my code looks like:
#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>
#include <ESP8266WebServer.h>
#define FIREBASE_HOST "pushst-56f2c.firebaseio.com"
#define FIREBASE_AUTH "mhBpzrNyhhwEGwmFxkVFTIEylwrXMw0gm"
#define PATH "/clients/devicename/watermotor"
IPAddress ip(192, 168, 1, 223); //Node static IP
IPAddress dns(192, 168, 1, 223);
IPAddress gateway(192,168,1,1);
IPAddress subnet(255,255,255,0);
char ssid[] = "MyNetwork";
char password[] = "Qwert98!!";
int wifiStatus = WL_IDLE_STATUS;
ESP8266WebServer server(80);
void setup() {
Serial.begin(115200);
delay(100);
Serial.println();
Serial.println();
Serial.print("Your are connecting to;");
Serial.println(ssid);
WiFi.begin(ssid, password);
WiFi.config(ip, dns, gateway, subnet);
while (WiFi.status() != WL_CONNECTED) {
digitalWrite(WIFI_CONNECT_LED, HIGH);
delay(500);
Serial.print(".");
}
wifiStatus = WiFi.status();
if(wifiStatus == WL_CONNECTED){
digitalWrite(WIFI_CONNECT_LED, LOW);
Serial.println("Your IP address is: ");
Serial.println(WiFi.localIP());
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
Firebase.set("/clients/devicename/watermotor/name", "Motor");
Firebase.set("/clients/devicename/watermotor/relay_status", "off");
Firebase.set("/clients/devicename/watermotor/device_status", "online");
Firebase.stream(PATH);
server.on("/on", handleOnRequest); //Associate the handler function
server.on("/off", handleOffRequest); //Associate the handler function
server.begin(); //Start the server
}
else{
Serial.println("");
Serial.println("WiFi not connected");
}
}
void loop() {
server.handleClient();
if (Firebase.failed()) {
Serial.println("streaming error");
Serial.println(Firebase.error());
delay(1000);
return;
}
if (Firebase.available()) {
Serial.println();
Serial.print("Firebase available");
Serial.println();
FirebaseObject event = Firebase.readEvent();
}
}
I am not sure if its there is some problem with FirebaseLibrary or its just the ESP8266!
Any suggestions will be helpful, thanks in advance! :)
