Hello I have a project where I sporadically have a disconect. I could trace the problem to the fact that it occurs when I send data more often than the pin (wirtuelWrite) I sometimes go up to 2000-3000ms or even more. Connection is a SIM800L. Could I somehow query the ping ?
What does that mean?
Are you using Blynk Legacy or Blynk IoT ?
What Blynk library version are you using?
What does your serial monitor show when these disconnections occur?

Check your GSM signal level. Command should be AT+CSQ for your module, I guess, or an equiwalent in your IDE, if you are not using AT commands. It depends on your GSM aerial and/or SIM800L placement. GSM module can lose packets when signal is bad (weak). And it could leading to disconnect. Justy a thought.
