Sending Data UDP from Arduino to InfluxDB

Hello community. So I’ve got an Arduino Uno and the Ethernet Shield V2 and connected these to a temperature sensor. Everything is working fine, the temperature is shown as desired, the problem is that I don’t seem to be able to save the results in my influxDB database.

Here my sketch:

#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
//
const int sensorPin = A0;
int sensorVal;
//
//
//
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};

byte host = {192, 168, 0, 153};
unsigned int port = 8089; // local port to listen on

EthernetUDP Udp;
//
//
//
//
//
void setup(){
//////////////////////
// PUT YOUR SETUP CODE HERE TO RUN ONCE
//////////////////////
//
//
//
Serial.begin(9600); // open serial port
//
//
Ethernet.begin(mac, host);
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield was not found. Sorry, can’t run without hardware. :(");
while (true) {
delay(1); // do nothing, no point running without Ethernet hardware
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println(“Ethernet cable is not connected.”);
}
// start UDP
Udp.begin(port);
}
//
//
//
//
//
float getTemperature() {
sensorVal = analogRead(sensorPin);
float voltage = (sensorVal/1024.0) * 5.0;
float temperatureC = (voltage - 0.5)*100;
//
return temperatureC;
}
//
//
//
//
//
void loop(){
//////////////////////
// PUT YOUR MAIN CODE HERE; TO RUN REPEATEDLY
//////////////////////
//
//
//
String line, temperature;
delay(1000);
temperature = String(getTemperature(), 2);
Serial.println(temperature);
line = String(“temperature value=” + temperature);
Serial.println(line);
//
//
Serial.println(“Sending UDP packet…”);
Udp.beginPacket(host, port);
Udp.print(“temperature value=”);
Udp.print(temperature);
Udp.endPacket();
//
//
//
}

These are the setting from the config file of the influxDB:
[[udp]]
enabled = true
bind-address = “:8089”
database = “arduino”

retention-policy = “”

InfluxDB precision for timestamps on received points ("" or “n”, “u”, “ms”, “s”, “m”, “h”)

precision = “s”

I would appreciate if somebody could give me some clues about what I’m doing wrong.

Cheers

you should send more detail of your environment, like InfluxDB versions and so on

try to enable a more verbose logging, and send here the details so we can figure what’s happening
