Kommt mir sehr bekannt vor! Ich sende auch nur ein einziges Paket!
Hier der Code der funktioniert:
Und dieser funktioniert nicht zuverlässig. Die Pakete kommen zwischen ca. 10s - 500s an (Unterschied nur in den letzten, nicht mehr auskommentierten Zeilen):Code:#include <ESP8266WiFi.h> //ESP8266 Core WiFi Library (you most likely already have this in your sketch) #include <WiFiUdp.h> #include <DHT.h> #define DHTPIN 0 #define DHTTYPE DHT22 //Init DHT-Sensor DHT dht(DHTPIN, DHTTYPE); //set IPs IPAddress IPudp (192, 168, 10, 68); IPAddress IPlocal (192, 168, 10, 201); IPAddress IPdns (192, 168, 10, 1); IPAddress IPgateway (192, 168, 10, 1); IPAddress IPsubnetmask (255, 255, 255, 0); //*******DeviceID-config************************ char UnitID[] = "id_1"; //****************************************** unsigned int receiveUdpPort = 5006; unsigned int sendUdpPort = 5005; char ssid[] = ("xxx"); char passphrase[] = ("xxx"); char charTemp[10]; char charHum[10]; int sendingStat; WiFiUDP udp; void setup() { Serial.begin(115200); delay(1000); Serial.println("\n\nSerial connection started"); WiFi.mode (WIFI_STA); //WiFi.config (IPlocal, IPdns, IPgateway, IPsubnetmask); WiFi.begin(ssid, passphrase); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); Serial.print(WiFi.status()); } WiFi.printDiag(Serial); Serial.print(WiFi.status()); pinMode(12, OUTPUT); Serial.printf("Now listening at IP %s, UDP port %d\n\n", WiFi.localIP().toString().c_str(), receiveUdpPort); delay(5000); } void loop() { digitalWrite(12, HIGH); delay(3500); float hum = dht.readHumidity(); float temp = dht.readTemperature(); digitalWrite(12, LOW); dtostrf(temp,5,2,charTemp); dtostrf(hum,5,2,charHum); delay(1000); if (isnan(hum) || isnan(temp)) { Serial.println("Sensorfehler!"); udp.beginPacket(IPudp,sendUdpPort); udp.write(UnitID); udp.write(" Sensorfehler\n"); udp.endPacket(); } else { long rssi = WiFi.RSSI(); Serial.println("Sending Sensordata"); if (!udp.begin(receiveUdpPort)) { Serial.println("UDP Socketerror"); } Serial.printf("Now sending UDP on port %d \n", sendUdpPort); udp.beginPacket(IPudp,sendUdpPort); udp.write(UnitID); udp.write(" "); udp.write(charTemp); udp.write(" "); udp.write(charHum); udp.write(" "); udp.write(rssi); sendingStat == udp.endPacket(); yield(); if(sendingStat = 1) { Serial.println("UDP Packet successful send"); } else { Serial.println("UDP Packet not send"); } Serial.println("Wait 0,5s.."); delay(500); Serial.print(" UDP Destination IP: :"); Serial.println(IPudp); Serial.print(" UDP Port: "); Serial.println(sendUdpPort); Serial.print(" Device ID: "); Serial.println(UnitID); Serial.print(" Temperatur: "); Serial.println(charTemp); Serial.print(" Relative Luftfeuchte: "); Serial.println(charHum); Serial.print(" Daempfung: "); Serial.println(rssi); //udp.stop(); //WiFi.disconnect(); //WiFi.mode(WIFI_OFF); Serial.println("wait 5,5s"); delay(5500); //Serial.println("ESP goes to deepsleep 60s"); //ESP.deepSleep(60e6); delay(100); } }
