Unicast examples
****************
1. [Central] Create CIG:

Requires to be connected:

.. code-block:: console

   uart:~$ iso cig_create
   CIG created

2. [Peripheral] Listen to ISO connections

.. code-block:: console

   uart:~$ iso listen txrx

3. [Central] Connect ISO channel:

.. code-block:: console

   uart:~$ iso connect
   ISO Connect pending...
   ISO Channel 0x20000f88 connected

4. Send data:

.. code-block:: console

   uart:~$ iso send
   send: 40 bytes of data
   ISO sending...


5. Disconnect ISO channel:

.. code-block:: console

   uart:~$ iso disconnect
   ISO Disconnect pending...
   ISO Channel 0x20000f88 disconnected with reason 0x16


Broadcast examples
******************

Setting up broadcaster
======================

.. code-block:: console

   uart:~$ bt init
   Bluetooth initialized
   uart:~$ bt adv-create nconn-nscan ext-adv
   Created adv id: 0, adv: 0x200025d0
   uart:~$ bt per-adv-param
   uart:~$ iso create-big
   BIG created
   ISO Channel 0x200008c0 connected
   uart:~$
   uart:~$ bt adv-start
   Advertiser[0] 0x200025d0 set started
   uart:~$
   uart:~$ bt per-adv on
   Periodic advertising started
   uart:~$
   uart:~$ iso broadcast
   send: 247 bytes of data with PSN 4350
   ISO broadcasting...

If encrypted broadcast is required, then a broadcast code can be provided as

.. code-block:: console

   uart:~$ iso create-big enc 00112233445566778899aabbccddffff
   BIG created

Setting up sync receiver
========================

.. code-block:: console

   uart:~$ bt init
   Bluetooth initialized
   uart:~$ bt scan on
