rpl-udp example: Not reachable yet #17

Closed fkerem closed 3 years ago

Hi,

rpl-udp example does not run properly in the testbed. Normally, it works properly in the Cooja simulator. Here is the serial link output in the Saclay site; node-a8-105 is rpl-udp server, other are the clients:

`

rpl-udp client nodes print out Not reachable yet.

What can be the issue?

fkerem commented 3 years ago

The issue did not arise in Grenoble, im investigating.

fkerem commented 3 years ago

I don't really know what is the root cause for this but rpl-udp example sometimes works sometimes do not work by printing out Not reachable yet message. I tested this in different sites.

fkerem commented 3 years ago

The reason for this was I was using the latest commit of contiki-ng but the users of the testbed should use the contiki-ng version which is used as the submodule in the repository: https://github.com/contiki-ng/contiki-ng/tree/20c6bb8f8f21124b3ba9ba079b2625acf5868ebd
