I've been working on a project with arduino UNO and GSM Shield.
I'm uploading to Internet data every 15 minutes from a maxbotix sensor.
Gsm Shield hangs and loops infinite with the serial monitor showing [url removed, login to view]() waiting for reply.
I have read very carefully all the related forums and rewrote the library file [url removed, login to view] as per [url removed, login to view]
Unfortunatelly this doesn't solve the problem. With gsm debug set to true it stucks on the the infamous AT%13% (post [url removed, login to view])
This is driving me mad as it ruins the whole project.
As I don't answers from the forum. I am seeking for professional help to solve the problem. I will accept the help and paid of someone that has the solution.
