• Enable 6LoWPAN over Bluetooth
  1. modprobe bluetooth_6lowpan
  2. echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm
  3. echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
• Connect device to host
  • echo "connect XX:XX:XX:XX:XX:XX 2" | sudo tee /sys/kernel/debug/bluetooth/6lowpan_control

IPv6 configuration in /etc/sysctl.conf, all can be replaced with interface name

• net.ipv6.conf.all.accept_ra=2 - Enable or disable SLAAC
