Describe your problem here
Can't get the smallest Sketch in Arduino IDE for OTA update (from internet) to work
Always Errors
In Arduino IDE => Connection refused
HTTP_UPDATE_FAILED Error (-1): HTTP error: connection refused
in PlatformIO => The famous Stream Read Timeout !
Using IDF with the same link I'm putting below , OTA works , It's just Arduino Core
#include <Arduino.h>
#include <WiFi.h>
#include <HTTPClient.h>
#include <HTTPUpdate.h>
WiFiClient client;
static void InitWifi()
{
Serial.println("Connecting...");
WiFi.begin("wifi ssid", "wifi pass");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
//hasWifi = true;
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void setup() {
Serial.begin(115200);
InitWifi();
}
void loop() {
t_httpUpdate_return ret = httpUpdate.update(client, "http://mymodbus.weebly.com/uploads/1/3/2/1/132175186/firmware.bin");
// Or:
//t_httpUpdate_return ret = httpUpdate.update(client, "server", 80, "file.bin");
switch (ret) {
case HTTP_UPDATE_FAILED:
Serial.printf("HTTP_UPDATE_FAILED Error (%d): %s\n", httpUpdate.getLastError(), httpUpdate.getLastErrorString().c_str());
break;
case HTTP_UPDATE_NO_UPDATES:
Serial.println("HTTP_UPDATE_NO_UPDATES");
break;
case HTTP_UPDATE_OK:
Serial.println("HTTP_UPDATE_OK");
break;
}
