Best way to send message to esp32 to change pin state

[ddelorme]

Well after some more testing I have an issue?
When the device is powered via USB it will run for days.
But when i use 12V power it crashes after about 12 hrs.
I checked the power supply, buck converter all seem well in spec range.
I turned debug on in the Arduino IDE and I am getting this error. every time i use the getLight function.
setting the timeout has no effect.

Code:

[E][WiFiClient.cpp:236] setSocketOption(): 1006 : 9

0x1006 is defined as

Code:

#define SO_RCVTIMEO 0x1006 /* receive timeout */

I dont know if this is my issue but it is the only error coming out of Debug.
The request is working and i get data back.

Here is the code i use.

Code:

void getlight()
{
 uint16_t time = millis();
 static uint16_t last_time;
 uint16_t dt = time - last_time;

 if (dt >= 1000) { // output every 1s
   last_time += 1000;
   if ((WiFi.status() == WL_CONNECTED)) { //Check the current connection status
     HTTPClient http;
     //http.setTimeout(10000);
     http.begin("http://192.168.1.7:3000/signalk/v1/api/vessels/self/sensors/anchorLight"); //Specify the URL
     int httpCode = http.GET();
     
     //Make the request
     if (httpCode > 0) { //Check for the returning code
       String payload = http.getString();
       StaticJsonBuffer<500> jsonBuffer;
       JsonObject& root = jsonBuffer.parseObject(payload);
       int code = root["value"];
       http.end(); //Free the resources
       if (code == 1) {
         digitalWrite (ALT_PIN, HIGH);  // turn on the LED
       } else if  (code == 0) {
         digitalWrite (ALT_PIN, LOW);  // turn off the LED
       } else {
         Serial.println("Fail");
       }
       
       return;
     } else {
       Serial.println("get http failed");
     }
     
   } else {
     Serial.println("Error on HTTP request");
   }

 }
 
}
