Node MCU sending data trough blynk to M5stick C

The SketchBuilder example doesn’t have other people’s own code mingled in with it - it’s as simple as it gets.

If you don’t understand that then maybe your Blynk programming skills aren’t ready for bridging yet.

Maybe you should read this, and it may make the receiving end of the bridge make more sense…

I’d start by adding a serial print command to the receiving device’s BLYN_WRITE(V5) function to show you that data has been received, and what the value of that data is.
