ISSUE - Running setup below works rock solid but I have noticed that if my IOS phone is powered off and i turn my phone back on and then check my Blynk app it will show the Blynk program still running and connected to my Arduino ok for about 1 second then it will stop and I get the Arduino Uno is offline message. I am able to replicate this every time.
Any suggestions?
Setup = IOS 8.3
Uno+Sainsmart W5100 Ethernet

- For this example you’ll need SimpleTimer library:
