Transfer programs M1306B to Q2686 - OpenAT V2.10 to 4.00

I developped an Open AT V2.10 application with Cygwin.
And I downloaded;

1- ftr_open_gprs_both.dwl 204 bytes
2- ftr_ip.dwl 193 bytes
3- eDSoft_W302_V210.dwl 116686 bytes
4- gprsrtd.dwl (my program) 142854 bytes

to M1306B Gprs Modem and it works, perfect.

And then, I bought Wismo Quick Development board
with Q2686 modules.
I converted the same application to Open AT V4.00
with Cygwin and minor differences like below;

ed_SocketSetConfig( &Socket ); Open AT V2.10
ed_SocketSetConfig( ED_ID_TCPSOCKET_1, &Socket ); Open AT V4.00

Now, what files must I download into Q2686 module?

I fear i have to disappoint you. The new internet libary is WIPlib for Q26XX family. However, i know that an alpha version of the Edlib exits for the OAT 4.00 ( as far as i know ) you can give it a try, but i think you should start with OAT 4.21 and use WIPlib instead for several reasons.
