I am using an Arduino Mega + WiFi shield for my project. I am sending emails using Temboo from my project but I am having an issue. Whenever a specific passcode is to be entered on a keypad, an email must be sent. However, it sends once and otherwise it gives HTTP_0, email does not send basically. When I reset it, it sends again like the previous time, only once. If I close the serial monitor and open it again, its like reseting it and the email works for once only. Can someone explain this if you have any idea?
