BLYNK_WRITE(V1) error message

[PeteKnight]

Okay, a few observations…

1. I don’t see the SimpleStream connection type, using a script running on a computer to provide a serial to internet communication interface, as a permanent connection solution. It’s fine for getting started with Blynk, but you’ll not get reliable and consistent results that way, as the CMD window on the computer needs to be open all of the time and the computer cannot be allowed to sleep.

2. You’ve set-up a “DebugSerial” port using SoftwareSerial. This will serve no purpose unless you have an FTDI adapter connected to pins 2 & 3 of your board top view these debug messages.

3. the hardware serial port (Serial) needs to be used exclusively for the SimpleStream communication. You can’t send debug serial data to this port like this, It will interfere with the SimpleStream communication (as you’ve discovered):

@David123

Serial.print(“Temperature = “); //Print text in quotation marks
Serial.print(roomTemp); //Print measured temperature
Serial.println(” Degrees Celcius”); //Print text in quotation marks
Serial.println(“”);

Serial.print("PWM Value = "); //print the text in quotation marks
Serial.println(Output);

4. You don’t need multiple BlynkTimer objects. One object, preferably called ‘timer’ can handle up to 16 separate timers.

Pete.
