Re: [wakaama-dev] lwm2m client bootstrapping failure and segfaulting
|
Hi Ricky,
I'm using wireshark to capture packets on all (Any) interfaces without applying filters so it would be strange if it's a wireshark problem as I do see CoAP traffic, only that the client does not seem at all to contact the bootstrap server. But it sends CoAP packets to the Lwm2m server just fine.
All three executables are running in local host.
I'll have a look through the code and see if I can perhaps find what's going on.
Regards
Bill

Hi Bill,
I think it may be caused by wireshark. I can't see bootstraping package with coap filter in wireshark for a long time.
Do you see UDP on wireshark log?
When I connect to leshan.eclipse.org<http://leshan.eclipse.org> bs server, the wireshark can't parse bs command.
You can try with udp||coap or use (ip.src == ip || ip.dst == ip) filter in wireshark.
For example: leshan.eclipse.org<http://leshan.eclipse.org>
(ip.src == 5.39.83.206 || ip.dst == 5.39.83.206)

Hi Christian,
Yes I have, with the same problem. It appears the lwm2mclient does not send any traffic to the bootstrap server even with '-b' option, but transmits packets to the lwm2mserver after a short interval.

Bill

Hi Bill,
have you tried the same setup without the -4 flag? Is there any difference in results?
