Does libcoap with LwIP supports Client applications ?

I don't see why it should not be able to do this. There currently is only a server example, and it should not be difficult to add a client example if someone wants to volunteer.

Hello
Thanks for your time and work with this lib

may be "it should not be difficult to add a client example", but can you (@mrdeep1 or @obgm) help in this questions:

• how to create client session with lwip, that will be equal to client in libcoap-minimal repo?
• coap_io_lwip.c tested with coap client build?

what I try to do:
coap_session_t *session = coap_new_client_session(ctx, &src, &dst, COAP_PROTO_UDP);
-> coap_session_t *session = coap_session_create_client(ctx, local_if, server, proto);
-> and in line 823 of coap_session.c
->

libcoap/src/coap_session.c

Line 819 in df9071c

if (!coap_socket_connect_udp(&session->sock, local_if, server,

and next, in coap_io_lwip.c, in function coap_socket_connect_udp()

libcoap/src/coap_io_lwip.c

Line 193 in df9071c

return 0;

finaly, I goto error; and session == NULL, and I'm here with the same problem as topic starter

PR #884 has been raised which provides LwIP coap-client support.

Closed as fixed in #926 which is now in the develop branch. Client support is now available.
