Sebastián Camilo Castaño / Mbed 2 deprecated Tarea6_GSM

Se usa un celular Siemens A56i para la comunicación por GSM,la aplicación consiste en esperar un mensaje de texto con la frase "Donde estas?","donde estas" o "donde estas?" que es enviada al Siemens desde cualquier otro celular, para así devolverle al remitente un link de Google Maps con las coordenadas de donde se encuentra en ese momento suministradas por un GPS, que en este caso será un computador que las envía a través de un Dongle conectado,usando el programa de SatGen con un .kml cargado de Google Earth o usando el simulador GPS de Proteus (funciona para ambos casos).

Dependencies:   GPS_G mbed
