Hi,
I’ve replaced the Arduino UNO same problem so NOT a hardware issue.
The problem only occurs when using BlynkSimpleWifi.h and calling Blynk.run()
There’s no problem when using BlynkSimpleEthernet.h and calling Blynk.run()
…
My conclusion there’s a defect in BlynkSimpleWifi.h … assuming memory addressing related…
Bruno.
