I tried "as it is" the contiki demo with SmartRF06 + cc2650EM and with sensortag. The demo seem working well but nodes rebooting (halt and watchdog make reboot) or stop working after about 10 minutes (the uptime is always under 600 sec).
If i turn on only 6lbr function (not mqtt, not coap) nodes seems remains alive (i monitored with serial console and make it write the uptime every 6lbr function call)
If I turn on mqtt or coap functions nodes reboots or halt after about 10 minutes
If i turn on only 6lbr function but I check web page of node from 6lbr sensor page, nodes stop working after about 10 minutes (web page is not available and serial console is blocking)
I tried to debug mqtt functions but there is any error, the console is stopping everytime after this log (I added some info to normal debug):

Some ideas? Is strange that is 10 minutes.
Thank You
