[edit] Creating a channel, capable of 6lowPAN (IPv6)
[RFC7668] "IPv6 over Bluetooth LE is dependent on both Bluetooth 4.1 and IPSP 1.0 or ..."
Reading http://blog.bluetooth.com/bluetooth-meet-the-internet-internet-say-hello-to-bluetooth you find that BLE uses Generic Attribute Profile (GATT) which is modular, and not Generic Access Profil (GAP) which is static and used by Bluetooth Classic.
GATT has many forms of which one is Internet Protocol Support Profile (IPSP) (Beware of HTTP Proxy Service (HPS) which is something completely different
Picture http://blog.bluetooth.com/~/media/images/blog%20images/migrated/smarthomerouter-01.ahsx (IPv6-BLE switch -> Gateway -> IPv6-Wifi-Bulb == All Native IPv6)
Command for setting what I am (IPSP)

> #hciconfig hci0 lestates > Read LE supported states on hci0 returned status 12 Yep, 0x0c or 12 is for unsupported command. So the fw doesn't seem to have support for LE. Let me get back to you on this, need to check up what fw is upon the repository.
Note If using a Linux kernel version less than 4.0, the kernel debug file 6lowpan_enable will not be present. Instead you should use "echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm" to set PSM channel as 0x23 (35), and enable the bluetooth 6lowpan module.

[edit] Setting an IPv6 address
following the lowpan 802.15.4 blog
- add
- apt-get install libnl-3-dev
- This is a strange page
- https://devzone.nordicsemi.com/f/nordic-q-a/14292/iot-sdk-rpi3---using-jessie-with-bluetooth_6lowpan
- that says:
- root@raspberry:/home/pi#
- root@raspberry:/home/pi# lsmod | grep 6lo
- root@raspberry:/home/pi# modprobe bluetooth_6lowpan
- root@raspberry:/home/pi# echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
- root@raspberry:/home/pi# modprobe bluetooth_6lowpan

- Another page
Now to establish my Bluetooth connection between the Raspberry Pis I run though the following steps: On the Master device I run the following commands:
#need root access sudo su #enable 6lowpan over Bluetooth le echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable #start advertising Bluetooth LE service hciconfig hci0 leadv
On the Slave device I run the following commands:
#need root access sudo su #enable 6lowpan over Bluetooth le echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable #establish le connection to master hcitool lecc 5C:F3:70:XX:XX:XX
The hcitool lecc command always returns “Connection Handle 64”. At this point I have a stable connection between the two devices that I can verify using the hcitool con command.
I am now able to run the following command on either the master or the slave where the mac address is the address for the Bluetooth device I am connecting too:
echo “connect 5C:F3:70:XX:XX:XX 1” > /sys/kernel/debug/bluetooth/6lowpan_control
Whichever Raspberry Pi I run the command on establishes a 6lowpan connection and if I run the ifconfig command I see a new bt0 device.

[edit] IPSP (Internet Protocol Support Profile)
This is *not* Bluetooth, bluetooth has fixed profiles such as A2DP https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_(A2DP)
The Generic Attributes (GATT) define a hierarchical data structure that is exposed to connected Bluetooth Low Energy (LE) devices.
The Generic Attribute Profile (GATT) procedures define standard ways that services, characteristics and their descriptors can be discovered and then used to allow Bluetooth Low Energy devices to transfer data. The profile describes a use case, roles and general behaviors based on GATT functionality.

IPSP is one of GATT https://www.bluetooth.com/specifications/gatt
