I’m clearly doing something wrong but I had assumed that I would be able to use the GSM and SIM900 libraries with the Seeed GPRS shield (after modifying gsm.h to reflect pin 7 and 8)
however when I startup a basic sketch it says it cannot communicate with the sim900 and to check the pin configuration
If I run the example code from the wiki I can make a call or send an sms without any issues at all however I want to be able to read an incoming sms
does anyone have any sketches that they are willing to share for reading a sms with this shield?
subsequently I am also having difficulty using my Leonardo as a serial pass through which may also indicate what is wrong however I have no idea what is going wrong as I said I am able to use the example on the wiki to communicate using software serial without any issues.
