Hello guys, now I have two cc2538 motes and want to set up a  UDP communication tunnel between these two motes, I use `gnrc_networking` from RIOT examples, but I found that I could not ping mote from another successfully. Here are two motes' interface configs:

I noticed that each mote's ipv6 address scope is `link`, not `local`, I guess the problem is RIOT don't get the write RF information from board or I missed some flags for switching on RF
Thanks for helping:)
