= 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 Profile===
 +
IPSP is one of GATT https://www.bluetooth.com/specifications/gatt
 +
 +
== Maybe a hint on how to detect whats IPSP, and whats not ==

Using rPi Zero W -> BLE -> 6LoWPAN -> XYZ to communicate over the Internet
IoT without Internet (Ip addresses) is *not* IoT !!!

WORK IN PROGRESS

Article: https://ieeexplore-ieee-org.ezproxy.server.hv.se/document/8390350 nrf51 supports 6lowpan: https://www.electronicsweekly.com/news/bluetooth-europe-2015-bluetooth-smart-ipv6-iot-2015-09/

[edit] SLAVE

lsmod               # Chech what your system already got -- If you get nice lines, you don't have to recompile your kernel :-)
modprobe bluetooth_6lowpan
lsmod | grep 6low   #gives three (3) lines
echo "1" > /sys/kernel/debug/bluetooth/6lowpan_enable
lsmod | grep 6low   #gives three (4) lines; now including  ipv6 -> 6lowpan
#rename hci0 to "whatever"
hciconfig hci0 name rpi-slave
# doing "hcitool lescan" on a third comupter shows nothing
# this cammand is undocumented ?!?
hciconfig hci0 leadv
# the slave now shows up as BCM43438A1

[edit] MASTER

modprobe bluetooth_6lowpan
lsmod | grep 6low #gives three (3) lines
echo "1" > /sys/kernel/debug/bluetooth/6lowpan_enable
lsmod | grep 6low #gives three (4) lines; now includes  ipv6 -> 6lowpan
hciconfig hci0 name Master
#Use address of other side's hci0 (Low Energy Create Connexion)
hcitool lecc B8:27:EB:C1:E9:42
# lecc should return "connection handle 65"
sleep 5
echo "connect B8:27:EB:C1:E9:42 2" > /sys/kernel/debug/bluetooth/6lowpan_control
#... eller ska det va en etta E9:42 1 ???!!  <type> is BLE address type: 1 for public address and 2 for random address.
#
#still nothing in ifconfig
ifconfig bt0 up
ifconfig   # Finally!

  1. If you are on a laptop two(2) hci devices will show up, the first one is buggy
    hciconfig hci0 down
  2. Now you can try scanning for BLE devices

[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)

> 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.

Command for viewing other end capabilities (IPSP ??)

[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
      root@raspberry:/home/pi# lsmod | grep 6lo
      bluetooth_6lowpan 24576 0
      6lowpan 36864 8 nhc_udp,nhc_routing,nhc_mobility,bluetooth_6lowpan,nhc_fragment,nhc_dest,nhc_hop,nhc_ipv6
      bluetooth 552960 32 btrtl,bluetooth_6lowpan,btintel,bnep,btbcm,rfcomm,btusb
      root@raspberry:/home/pi#

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.

Hi und danke erstmal,

bin jetzt soweit mit fast allen befehlen durch 

Code: [Auswählen]
pi@raspberrypi:~ $ ls -l /dev/ser*
lrwxrwxrwx 1 root root 7 Feb 28 23:59 /dev/serial0 -> ttyAMA0
lrwxrwxrwx 1 root root 5 Feb 28 23:59 /dev/serial1 -> ttyS0

das sieht schon mal gut aus, lt. deinem Howto
allerdings bekomme ich dennoch kein Device : 

Code: [Auswählen]
pi@raspberrypi:~ $ hcitool dev
Devices:
pi@raspberrypi:~ $ hcitool scan
Device is not available: No such device
pi@raspberrypi:~ $ 

glaub bin zu müde oder zu blind.
habt Ihr eine Idee ??

danke

sudo apt-get --reinstall install pi-bluetooth

sudo shutdown -r now

[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.

[edit] IPSP Profile

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

[edit] Maybe a hint on how to detect whats IPSP, and whats not
