Dear Friends,
I am using sim900 modem to transfer data to a server using at commands .
I am establishing TCP CONNECTION USING at Commands.
The connection does establishes but gets closed automatically after some time...How can i keep it alive indefinitely......
My application:
Need to send data to a remote server via tcp....
First it will attempt to send over gprs , if gprs fails then via sms .
This concept does works but the connection gets closed after some time automatically. Plz suggest where i am missing something.I suppose it has to be keeping the connection alive for indefine time but i dont know which AT command to use for that. Plz help...
I get a close response from the gsm modem after some time after which i am not able to connect with the server until i establish the connection again running all the at commands again....
Please suggest how to proceed...
