I have developed some application on wavecom q2686 module,.
my application is to receive the data from uart and upload the data to FTP server at regular interval .
In this I need to upload the data once in an hour .
I tried to implement this using TCP client sample program provided in the Open AT os . I am able to upload the data , but the problem is after some time IP gets terminated or device gets restarted , so I cant upload the next data , This happens irregularly and do not know why this happens.
How to over come these problems .?
How to make the GPRS enable only when I need to send the data to server…? i.e sim should be subscribed at the starting of the device and GPRS can be able to enable before sending the data and disable it once the data has been sent .
