There are some functions that are called on connect and on disconnect. In the disconnect you can cause a WDT reset. See the 2 links below.

Hi.
Thanks for help.
If want reset Arduino then need uncomment //BlynkOnDisconnected(); in BlynkProtocol.h then work function CAYENNE_DISCONNECTED() .
If this working then I reset MCU by watchdog … I use 120ms … now I will see in long time if it working or not …

thanks and best regards.
