What does your serial monitor show when this happens?

Have you checked all the connections and tried a different power supply, USB cable and board?

Your serial monitor shows no disconnection info, I wanted to know what was displayed when a disconnection occurs.

BTW, you’re far better using the baud rate of 74880 in your sketch, and then set your serial monitor to this baud rate too. You’ll then see intelligible boot data from the D1 Mini instead of this…

It’s also best to turn-on timestamps in the serial monitor, it adds perspective relating to timings.

Pete.

Pete.

ok. here with the other baudrate and timestamp

I’m seeing the device connecting to Blynk, but no disconnection
The disconnection is why you began the topic, where is it, how do you know it is occurring??

Pete.

In the App you can first read the dialog “connected”. after round about 3sec “disconnected” and after a time you see the missed controller symbol in the right corner

But your device isn’t saying that it is disconnected in the serial monitor?

Pete.

no. only in the app. may be it´s a problem with the blynk sever? the sketch is the same,
controller, power and cable is ok

Do you have just one device in your app?
Is your auth code used in any other devices?

Have you tried generating another auth code and using this in your sketch?

Pete.

I have one project with three devices and also auth token.
before 4-5 days everything was ok. but from yesterday to now it changed.
i have no idea.

And the other two devices stay online without any problems?

Pete.

Sure, another wemos D1 Mini, cable and power supply and also a new token.
So Pete,for today thank you and have a good night. see you tomorrow
