Limitations and Recommendations

  • Don't put Blynk.virtualWrite and any other Blynk.* command directly inside void loop()- it will cause lot's of outgoing messages to our server and your connection will be terminated;
  • We recommend calling functions with intervals. For example, use BlynkTimer
  • Avoid using long delays with delay() – it may cause connection breaks;
  • If you send more than 100 values per second - you may cause Flood Error and your hardware will be automatically disconnected from the server;
  • Be careful sending a lot of Blynk.virtualWrite commands as most hardware is not very powerful so it may not handle many requests.
