As coap-server now sets up 2 (or 4) endpoints, UDP and TCP based, all subsequent endpoints are pre-pended to the ctx->endpoint list. Thus ctx->endpoint will always be TCP based. Setting IPV6_JOIN_GROUP on a TCP socket is a no-no. As join() is complex function, it should be within libcoap so as to not require detailed knowledge of how internal structures work (which really should be opaque to the application writer). include/coap2/net.h: src/net.c: libcoap-2.map: libcoap-2.sym: Create coap_join_mcast_group() in src/net.c (as it is a network layer function using the (fixed) join() code. (Iterate through the ctx->endpoint list looking for UDP based endpoints and only do the IPV6_JOIN_GROUP on them.) There is no support for WITH_CONTIKI or WITH_LWIP at this point (returns -1). examples/coap-server.c: Remove join() code and replace call to join() with coap_join_mcast_group() examples/coap-rd.c: Remove join() code and replace call to join() with coap_join_mcast_group() man/coap-rd.txt.in: Correct a typo in the coap-ed man page
