Hi all

Here is my environments.

- WICED SDK 2.4.0

- ThreadX/NetX Duo


In field test, I found that some DHCP server(DHCP proxy) replied DHCP-Offer with Unicast not Broadcast.

Then, WICED module(netx) can't go on anymore as below.

I think that this is internal issue of ThreadX/NetX library.

(I can't use the lwip for some reason.)

Is any way to solve this problem?

Regards, Steve

Hi,

Could you please try the attached patch and library for SDK-2.4.0?

Attached NetX_Duo.ARM_Cortex_M3.release.a replaces the .../Wiced/Network/NetX_Duo/NetX_Duo.ARM_Cortex_M4.release.a library.

Hi sehyan

My platform is <BCMUSI11>, but I don't think that this problem is related to the platform.

I guess that this is about dhcp-client-library of NetX.

And, technically speaking, I think that if WICED module(NetX-dhcp-client) send a DHCP-Discover-with-Broadcast, DHCP Server should reply DHCP-Offer-with-Broadcast (not DHCP-Offer-with-Unicast).

Actually most DHCP-server reply DHCP-Offer-with-Broadcast.

But, "sometime-DHCP-server" would reply DHCP-Offer-with-Unicast, and in this case WICED module(NetX-dhcp-client) can't go to next-step.

In the same-conditions, Linux, smartphone, windowns and another dhcp-client can go to the next-step and get a IP from DHCP-serer.
