thank you for help

I assume that when you say “my own server” you mean a Blynk legacy local server?

If so then what version of the Blynk library and Blynk local server are you using?

Pete.

3

my onwer server blynk server 1.0

4

but I have one board all good work connect Blynk, and the second two boards it. I don’t understand… how is it?

5

Can’t help unless you answer my questions…

Pete.

6

blynk 1.0.0 and yes blynk local server Qnap.

7

You need to be using v0.6.1 of the Blynk library.
I’d expected an answer that began with v0.41.xx for your local server version.

I’d also try to avoid v3.x.x of the ESP32 core with this old Blynk library, and you may even need to go back to a fairly old version of the v2.xx.x core if you still have issues.

Can’t be more specific unless you can be more specific about your own setup.

Pete.

Thank you,
but I managed to find it. I know the reason…
best regards

Normal protocol would be for you to share that reason, so that others in the same position can learn from your experience.

Pete.
