Hi eric, I have set softwareserial buffer. I have modified y boot time to 10sec (i.e 10000) . I guess this will make some issues. Whenever I send sms, only red LED Blinks, SIM 900 doesn't have reset pin so I modified that portion of code.. I already have a similar kind of system for controlling My agricultural 3phase induction motor, for controlling motor I used SMS, I liked your project with your design by making call motor can be controlled..so I am trying to update my system to your design.. Kindly help me,
Hi Eric. I am using sim900, and I modified everything to my setup.If I send SMS as MASTER I'm.getting only Red blinks, no success
