[En-Nut-Discussion] Ethernut/GPRS router

[Mike Cornelius]

Hi Lee,

Further to Harald's responses:-

There's no real need for GPRS drivers as such if you want to use the
standard ethernut hardware, to establish a GPRS session all you need do is
send 2 at commands to the GPRS modem, specifically,

Set the GPRS context
AT+CGDCONT=1,"IP","internet"	(for example).

Dial 'GPRS'
ATD*99#

Which as Harald suggests can be done via the chat mechanism.

BTW
We manufacture a complete hardware solution to suit your description, have a
look at our iT products at http://www.call-direct.com.au/gsm-gprs_modems.htm
These include:-
GPRS Phone module
ATMEGA 128
32k SRAM
Nut/OS (Of Course)
10BT Ethernet

We've not actually had any demand for a GPRS NAT router as you describe but
I did envisage making such a thing, this missing link as Harald suggests is
the NAT.

I wouldn't expect that producing a NAT driver for Nut/OS would be too
difficult.

Regards,

Hi guys,

With all this talk of PPP/GPRS components, has anybody tried producing a
cheap GPRS router based on the Ethernut. Didn't a newsgroup member mention
interest in a similar project ?

Does the Ethernut include all the necessary components to provide routing
capability:

1. NAT
2. ARP
3. RARP
4. DCHP server
5. PPP
6. GPRS drivers

This would be an excellent project if it's achievable on the Ethernut.

Regards,

Lee
