neopixel strip and blynk

Using Arduino Programming Questions
#1

Hello,

I have a (adafruit) neopixel ledstrip which I connect to my ESP8266. I want to control the strip (colors and paterns) with my phone so I use Blynk.
I already can change the color of the srtip using BLYNK_WRITE(v1). I can also run the chase by blynk-connecting a button to v2 but it will only run 1 time when I push the button.

How I can repeat this “Chase” as long as the button (switch) is on?

How I can repeat this "Chase" as long as the button (switch) is on?

You start by providing links to the libraries that you are using. There is nothing in the code you posted that explains how BLYNK_WRITE() gets called, or what Blynk.run() does.

So, the issue appears to be in the unknown libraries that you use or the app that sends data to the not-an-Arduino.
