Unable to send packets with UDP sock #8457
Description
Hi people,
Description
I was working with a simple sock UDP client/server code when I noticed I lost the ability to send UDP messages. Though, the gcoap example is working fine.
As I was unable to determine the source of my problem, I run test/gnrc_sock_udp in the current master and got errors. Can anyone else confirm this behavior?
Steps to reproduce the issue
tests/gnrc_sock_udp$ BOARD=native make all test
Expected results
Execution of the test with the release 2017.10:
./tests/01-run.py
/home/rfuentess/Projects/RIOT/tests/gnrc_sock_udp/bin/native/tests_gnrc_sock_udp.elf
RIOT native interrupts/signals initialized.
LED_RED_OFF
LED_GREEN_ON
RIOT native board initialized.
RIOT native hardware initialization complete.
