No. 1296 Re: Re: cannot access atcommand mode 2014-11-19

Hi,
Thank for support. Now i can connect by tcp/ip by AT command.
I have another question:
I try to send 1kbyte data to server, but in several time, server could not receive data from module although Ethernet Status pin still signal is connect, 10 second late, the module disconect to server. If i send less data than 1kb, module can keep connect to server for a long time but still disconnet.
How could i keep the module always connect to server without auto disconnect?
Thank for help!
