I am connecting my arduino with a GPRS Shield to Blynk, i am reading the temperature and the humidity from a DHT11 sensor. I allready did the connection, but i dont know why after some seconds sending data it stops and i have to reset everything several times to get connected again. Please help me with this, thanks.

We don’t know either :wink:

Perhaps a few more details, including versions of everything you are using; exact hardware, Blynk library, App, Phone, etc… and show us the full code you are using (after reading the Welcome Topic please - so you know how to properly format that code after pasting it here).
