Hi,
I just read IoT-MQTT example and have almost exactly the same problem but with the Publisher.
I am running a PI with Raspberian 4.4.34-v7+. I have installed mosquitto on the PI and have radvd installed. I turned on the IPV6 forwarding (echo 1 > /proc/sys/net/ipv6/conf/all/forwarding), did the config file and restarted radvd. This worked ONCE. I did get this:
sudo echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
root@raspberrypi:/home/pi# sudo service radvd restart
root@raspberrypi:/home/pi# ifconfig bt0
bt0 Link encap:UNSPEC HWaddr B8-27-EB-FF-FE-F1-72-D4-00-00-00-00-00-00-00-00
inet6 addr: 2001:db8::ba27:ebff:fef1:72d4/64 Scope:Global
inet6 addr: fe80::ba27:ebff:fef1:72d4/64 Scope:Link

TX packets:52 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:1906 (1.8 KiB) TX bytes:2808 (2.7 KiB)
This is with the Publisher connected to bt0. The publisher has the 2001:... address compiled in. I then run mosquitto -v on the PI but when I press button 1 all 4 LED's light up and stay lit showing it failed. I get no messages on mosquitto.
But now if I disconnect and re-connect bt0 does NOT have the global address anymore. I even re-booted the PI and did the whole sequence all over again starting with loading 6lowPAN and still it does not get the global address. Do you have any suggestions of what to try next.
And one more question. The disconnect does not work. When I try to do:
echo "disconnect 00:EF:0B:A4:88:A6" > /sys/kernel/debug/bluetooth/6lowpan_control
I get a write error of invalid argument. That is the correct MAC.
Thank you for the help. --jim schimpf
