Any progress in resolving the bug?
from emqx-coap.
Is there any messages when using libcoap
to send to emqx or recv from emqx?
For example:
coap-client -m put -e 1234 "coaps://127.0.0.1/mqtt/topic1?c=client1&u=tom&p=secret"
Apr 15 16:11:54.659 WARN do_gnutls_handshake: session establish returned -15: 'An unexpected TLS packet was received.'
Apr 15 16:11:55.664 WARN do_gnutls_handshake: session establish returned -10: 'The specified session has been invalidated for some reason.'
If so, you should use ./configure --enable-documentation=no --enable-tests=no --with-openssl
instead of ./configure --enable-documentation=no --enable-tests=no
. It is the diffrence between diffrent ssl libraries which leads to this error.

@qingchuwudi :
Thank you for the response.
I rebuilt coaplib but still have the same issue with no any notification from a client or a server.

@frizner We tested using emqx with 4.0.5 and libcoap with develop branch. It's working as expected.
Could you have a try? And if the same problem repeats, could you please post the Wireshark capture file of the DTLS handshake procedure?

Is there any progress on this issue? I'm also paying attention to this problem, because I've never succeeded in creating coups to connect emqx with the California framework. Can you share the Certificate creation command used in the test..
