I'm trying to combine 2 sketches as one wherein the first code is OTA through which I can push/update the code using the wifi and secondly is for home automation which controls my home lights/switch (ON/OFF) using Amazon Alexa.
Both codes work fine independently but give different errors when i copy past the second one below the first code.
Both codes need to upload over NodeMCU esp8266
but give different errors when i copy past the second one below the first code.
You should post an example of what you tried and the errors that you got, but I assume that you have at least combined the setup() and loop() functions from each program into single functions in the combined code.
[
OTA Code is as follow:-
#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>
const char* ssid = ""; //!!!!!!!!!!!!!!!!!!!!! name of your router
const char* password = ""; //!!!!!!!!!!!!!!!!!!!!!your wifi password.
WiFiServer server(80);
void setup() {
Serial.begin(115200);
Serial.println("Booting");
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);
while (WiFi.waitForConnectResult() != WL_CONNECTED) {
Serial.println("Connection Failed! Rebooting...");
delay(500);
ESP.restart();
}
// Port defaults to 8266
// ArduinoOTA.setPort(8266);
// Hostname defaults to esp8266-[ChipID]
ArduinoOTA.setHostname("Bedroom");
// No authentication by default
ArduinoOTA.setPassword((const char *)"123");
ArduinoOTA.onStart([]() {
Serial.println("Start");
});
ArduinoOTA.onEnd([]() {
Serial.println("\nEnd");
});
ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
});
ArduinoOTA.onError([](ota_error_t error) {
Serial.printf("Error[%u]: ", error);
if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
else if (error == OTA_END_ERROR) Serial.println("End Failed");
});
ArduinoOTA.begin();
Serial.println("Ready");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
server.begin();
}
void loop() {
ArduinoOTA.handle();
delay(10); } // delay to gife the arduino time to move to the next operation.

OTA Code is as follow:-
You can't simply paste two sketches together without editing them to make them work as one.
You'll need to integrate your 'void setup' and 'void loop' portions so you only have one of each.
Oh .. and forum rules say to surround your code with code tags before posting.
