The SIM800L Arduino Library is a simple and easy-to-use library for the SIM800L module, allowing for quick and efficient communication with the module using the Arduino platform.
I get "OK" when I send 'AT+DDET=1,1000,1,1* ' over uart .
But it doesnt seem to detect anything afterwards.
Perhaps I am doing something wrong.
Would appreciate some feedback.
