Hello All. I'm working on a project on Nodemcuv3. the project uses Adafruit IO MQTT Library and ESP8266 IRRemote Library. here is my code-
#include <ESP8266WiFi.h>
#include "Adafruit_MQTT.h"
#include "Adafruit_MQTT_Client.h"
#ifndef UNIT_TEST
#include <Arduino.h>
#endif
#include <IRremoteESP8266.h>
#include <IRrecv.h>
#include <IRutils.h>
uint16_t RECV_PIN = D5;
uint16_t L1 = D6;
uint16_t L2 = D7;
#define WLAN_SSID "xxxxxxxxxxxxxxxxxxxxxx"
#define WLAN_PASS "xxxxxxxxxxxxxxxxxxxxxxxxxx"
#define AIO_SERVER "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
#define AIO_SERVERPORT 1883
#define AIO_USERNAME "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
#define AIO_KEY "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
WiFiClient client;
Adafruit_MQTT_Client mqtt(&client, AIO_SERVER, AIO_SERVERPORT, AIO_USERNAME, AIO_KEY);
Adafruit_MQTT_Subscribe L1 = Adafruit_MQTT_Subscribe(&mqtt, AIO_USERNAME "/feeds/l1");
Adafruit_MQTT_Subscribe L2 = Adafruit_MQTT_Subscribe(&mqtt, AIO_USERNAME "/feeds/l2");
IRrecv irrecv(RECV_PIN);
decode_results results;
void MQTT_connect();
void setup() {
Serial.begin(115200);
delay(10);
irrecv.enableIRIn();
pinMode(L1,OUTPUT);
pinMode(L2,OUTPUT);
Serial.println(F("starting..........."));
// Connect to WiFi access point.
Serial.println(); Serial.println();
Serial.print("Connecting to ");
Serial.println(WLAN_SSID);
WiFi.begin(WLAN_SSID, WLAN_PASS);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println();
Serial.println("WiFi connected");
Serial.println("IP address: "); Serial.println(WiFi.localIP());
mqtt.subscribe(&l1);
mqtt.subscribe(&l2);
}
uint32_t x=0;
void loop() {
IRremote();
MQTT();
}
void IRremote() {
if (irrecv.decode(&results)) {
unsigned int value = results.value;
if (results.value == 0xJJ89QQ) {
digitalWrite(L1,HIGH);
}
if (results.value == 0xJJ90QQ) {
digitalWrite(L1,LOW);
}
if (results.value == 0xFFFCC5) {
digitalWrite(L2,HIGH);
}
if (results.value == 0xFFFCC4) {
digitalWrite(L2,LOW);
}
irrecv.resume();
}
}
void MQTT() {
MQTT_connect();
Adafruit_MQTT_Subscribe *subscription;
while ((subscription = mqtt.readSubscription(5000))) {
if (subscription == &L1) {
Serial.print(F("Got_L1: "));
Serial.println((char *)L1.lastread);
uint16_t num = atoi((char *)L1.lastread);
digitalWrite(L1,num);
}
if (subscription == &L2) {
Serial.print(F("Got_L2: "));
Serial.println((char *)L2.lastread);
uint16_t num = atoi((char *)L2.lastread);
digitalWrite(L2,num);
}
}
if(! mqtt.ping()) {
mqtt.disconnect();
}}
void MQTT_connect() {
int8_t ret;
if (mqtt.connected()) {
return;
}
Serial.print("Connecting to MQTT... ");
uint8_t retries = 3;
while ((ret = mqtt.connect()) != 0) {
Serial.println(mqtt.connectErrorString(ret));
Serial.println("Retrying MQTT connection in 5 seconds...");
mqtt.disconnect();
delay(50);
retries--;
if (retries == 0) {
while (1);
}
}
Serial.println("MQTT Connected!");
}
Now the problems are-
1.code is running ok with 0 error.but whenever i try to trigger L1/L2 via IR remote, it responses very lately,nearly 3-5 secends.
2.my target is to make a backup/ redundancy when there is no internet. if there is no internet, i want to trigger the I/O pins via IR remote.whenever i disconnect wifi from nodemcu,the IR remote stops working.
it there a glitch in a code? can anyone correct/solve it?
Thanks
