Hi All,
Recently I started using RIOT on my sam r21 xplained board. When I tried to ping between two boards running the sixlowapp application, the application hangs and I need to reset the board to continue working. Can anybody help me to understand it is so? 
The log below is taken after enabling debug in ip.c, icmp.c, sixlowshell.c, monitor.c, helper.c, lowpan.c

Node 1 (source from ping initiated)-----------
