examples: dtls-echo fails silently when DTLS_ECC flag enabled #11859
Description
Description
The example program fails silently when using ECC credentials instead of the default (PSK) . PSK still works. On native both PSK and ECC works.
Steps to reproduce the issue
- Uncomment the line
CFLAGS += -DDTLS_ECCin the Makefile - Compile and flash on two
samr21-xpronodes - On the server node, start the server with
dtlss start - On the client node, send a message to the server node:
dtlsc <ip of server node> HALLO
Expected results
On the client shell:
Client: got DTLS Data App -- HALLO --
On the server shell:
Server: got DTLS Data App: --- HALLO --- (echo!)
Actual results
Nothing on both client and server. On the client, the shell hangs for a few seconds while processing and then prompts for new shell input.
Versions
Tested with current master (3f25c43) on samr21-xpro boards.
