Description
My ESP32S2 POSTs a data packet to InfluxDb every 30-40 seconds. After recompiling my code today, now POSTing the data fails after about 5-7 packets. Wireshark shows that the ESP32 starts trying to send packets to 0.0.0.0. However, if I replace hostname with the IP, everything works fine. While the ESP32S2 is failing to POST data to InfluxDb, all the other networking stuff works OK- MQTT, OTA, ping.
The board manager shows version 3.0.0-rc3. I tried downgrading to rc2 - same result, Downgraded to 2.0.16 - works OK now.
I have at least 6 ESP32s sending data to InfluxDb without problem. All use hostname in the URL.
uri = String("http://") + host + ":8086/api/v2/write?org=" + org + "&bucket=" + bucket + "&precision=s";
The following code running on a Tiny Pico starts returning -1 after several minutes, Some time later, it will start returning a valid status (405 in my case). This pattern repeats.
Sketch
#include <WiFi.h>
#include <HTTPClient.h>
#include "arduino_secrets.h"
String postData = "Hello";
String url = "http://myhost:8080/";
void setup() {
Serial.begin(115200);
delay(2000);
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, pass);
while (WiFi.status() != WL_CONNECTED) {
Serial.print('.');
delay(1000);
}
}
void loop() {
WiFiClient client;
HTTPClient http;
http.begin(client, url);
http.addHeader("Content-Type", "text/plain; charset=utf-8");
http.addHeader("Content-Length", String(postData.length()));
int statusCode = http.POST(postData);
http.end();
Serial.println(statusCode);
delay(1000);
