Q24NG and custom TCP Stack


I’m thinking of using a custom TCP stack for a GPRS application.

Are the following procedures correct:

  1. Open GPRS session (eg. CGDATA command)

  2. Use the TCP/IP stack to open a socket to my server

  3. communicate

  4. Close socket and TCP

  5. Close GPRS.

… is the above correct or do I also need PPP

Hope to hear from you soon.
