I have an ESP32 that has 5 values (solarW, batteryV, pumpW, pumpRPM and pumpLPM) that I'm writing to 5 fields on a Thingspeak channel.
if ((millis() - fifteenTstart) > 15000){
Serial.println("Updating Thingspeak....");
ThingSpeak.setField(1, solarW);
ThingSpeak.setField(2, batteryV);
ThingSpeak.setField(3, pumpW);
ThingSpeak.setField(4, pumpRPM);
ThingSpeak.setField(5, pumpLPM);
int x = ThingSpeak.writeFields(myChannelNumber, myWriteAPIKey);
if(x == 200){
Serial.println("Channel update successful.");
}
else{
Serial.println("Problem updating channel. HTTP error code " + String(x));
}
}
It works fine when there's a good connection to the internet and Thingspeak, but there's a 10 second or so delay when Thingspeak is unavailable (WiFi, internet or website non-connectivity).
I would like the code to recognise that there's no ThingSpeak connection musch faster (1 second or less woud be good, but I'll take two!).
Or, if it's possible to just send the data out without the code waiting for a confirmation back (I only need the data to go OUT from the ESP32 to Thingspeak, nothing needs to come back).
The reason for doing this is there's other code on the ESP32 that I need to get back to, having a 10 second delay in the middle of the code ain't good for the pump safety reaction code.
