Bluetooth: IPSP Sample
######################
Overview
********
Application demonstrating the IPSP (Internet Protocol Support Profile) Node
role. IPSP is the Bluetooth profile that underneath utilizes 6LoWPAN, i.e. gives
you IPv6 connectivity over BLE.
Requirements
************
This application currently only works with HCI based firmware since it
requires L2CAP channels support.
Building and Running
********************
This sample can be found under :file:`samples/bluetooth/ipsp` in the
Zephyr tree.
Testing with a Linux host
=========================
To test IPSP please take a look at samples/net/README, in addition to running
echo-client you must enable 6LowPAN module in Linux with the
following commands:
.. code-block:: console
$ modprobe bluetooth_6lowpan
$ echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
Then to connect:
.. code-block:: console
$ echo "connect <bdaddr> <type>" > /sys/kernel/debug/bluetooth/6lowpan_control
Once connected a dedicated interface will be created, usually bt0, which can
then be used as following:
.. code-block:: console
$ echo-client -i bt0 <ip>
