Hi all
I tested a network camera, which seems work in this way:
it has a DHCP client inside, which starts on power on. But until an IP from
DHCP server is available, it answers on fixed ip (i.e. 192.168.1.3)
Can i do the same using lwip?
I tried to bring up an interface with fixed IP and after s
Hello,
I am in need of some support in using lwIP for my application. I hope you
will be able to reply on the queries, or atleast guide me to the proper
channel for such queries (if this is not the one!). Thanks in advance.
Here's what I intend to do in my application:
I have a DSP processor with 2
I think the kind of filtering you are describing is best done at
ethernet device driver level. If the incoming packet is to be passed
to the output part, it can be done from within the driver, keeping the
ethernet header and the rest. If the packet is to be processed by
lwip, it should be passed to
The real question is: do you really want to do that? what if you connect
2 cameras, what happens? plus the problem on another message...
IMHO, this would work better:
try DHCP for some time, withou any ip, then use autoip...

i found a solution... but i "forced" stack implementation guidelines...
I did a post to lwip_dev with this idea... because i need a feedback... here

Hi all.
I found a solution for my problem, but i need community feedback.
The problem is:
I have my ip board, and i need to simplify the
Piero,
In my Ethernet driver, I've done the following to allow an attempt at DHCP
with a fallback to a static IP.
int dhcpFallbackTimer = GetmSTimer() + 5000;
//5 seconds
while( ! netif_is_up( netif_default ) )

Thank you Thomas, Micael, and Simon for your replies. The decision wasn't
hard after considering the learning curve. Plus, there were a significant
number of serious bugs in version 7.2 most if not all reported fixed in 8.0.
It made me nervous that a version 7-something would have that many issue
Hi,
I have this too, you can do this by writing into the netif ip address directly
before starting dhcp (dhcp_start).
There is a bit of problem though, if the DHCP server offers an address equals
to the static address and ,
and after offering does acheck through ARP, your device will answer and

I agree - you really don't need a full TCP/IP stack for this purpose. I
would guess that at most you're going to want to be able to examine so
I think LwIP is much more memory efficient than Interniche. At least
when it comes to RAM.
Interniche requires that all rx buffers are of maximum frame size unless
you want to reallocate and copy each frame at the driver level. So even
small ACKs take a full ~1500Byte buffer.

Hi all,
i'm facing the same problem, but my solution was, to put the fallback
into the dhcp-timeout. Means: Startup the dhcp with 0.0.0.0 , if it is
getting an
ip , everything is o.k. , if not the static IP is used . ( see below ..)
The disadvantage of this is, that it takes 20 seconds, before
12 matches
