[lwip-users] Basics LWIP, PPP and GPRS

[Lasse Madsen]

Hi all.

 

Just a couple of simple questions

 

1. 

Does LwIP include PPP code (I have read that alot of people use their own) but I was just curious if its possible to connect a ME35 (Siemens GPRS modem terminal) to my microcontroller install LwIP and have it connect to GRPS and for instance open a TCP socket to (for instance) a Time server and read the time.

 

2.

How many simultanious sockets can be opened with LwIP ? does both TCP and UDP work ?

 

3.

Has anyone tried implenting LwIP to an Atmel AVR and maybe has some example code for PPP/TCPIP?

 

4.

Im about to design some new hardware for a board using a GPRS modem i have onboard on my Philips ARM 128KB flash and about 16KB SRAM

I was thinking of adding alot more SRAM what is recommended if i would want some sockets etc. ? (read: what do you guys run LwIP on?)

 

5.

Does LwIP include HTTP services ?

 

6.

Does LwIP support both Listening and "Server" sockets ?

 

Sorry for the "newbie" questions around LwIP but I think its such a great consept you are basing it on (GPL) and I hope to contribue at some point :-)

 

Best regards
