cord_ep example timed out when registering to a resource directory #14399
Description
Description
The cord_ep example application timed out when registering to aiocoap-rd resource directory (RD). Latest known working release is 2020.01.
Steps to reproduce the issue
With the latest master (e8389a5) or release 2020.04, start a cord_ep example application and try to register to the RD.
I'm using aiocoap version 0.4b3. Install with pip3 install --upgrade "git+https://github.com/chrysn/aiocoap@0.4b3#egg=aiocoap[all,docs]", the latest from aiocoap master seems to have some issue.
- Start the RD:
aiocoap-rd - From
cord_epexample terminal:cord_ep register [<RD ipv6 ip>]:5683
Expected results
Using RIOT release version 2020.01:
main(): This is RIOT! (Version: 2020.01)
CoRE RD client example!
Client information:
ep: RIOT-9F2723239F272323

> cord_ep register [fe80::a4b8:d3ff:feb5:d5aa]:5683
cord_ep register [fe80::a4b8:d3ff:feb5:d5aa]:5683
Registering with RD now, this may take a short while...
