Topic: GSM receiving calls Automatically? (Read 386 times) previous topic - next topic


Hello i know the At command for answering calls is ATA but in the arduino sketch  does it go like SIM900.print("AT+ATA=1\r"); to receive the call automatically in the Loop? Can someone please help me out thank you.


Never mind please forgot get this Post i have figure it out. Because i was using a arduino mega and was getting nothing responded back i thought something was wrong with the sketch or gsm shield and i know it use to work but tuned out its was the Spi pins sense its on a mega from d50 to D53 and the pins on the gsm shield require D10 to D13 i forgot in the past i had a uno board on it. that was my problem the whole time.
