Bluetooth: Central ISO
######################
Overview
********
This sample demonstrates how to use an isochronous channel as a central.
The sample scans for a peripheral, establishes a connection, and sets up a connected isochronous channel to it.
Once the isochronous channel is connected, isochronous data is transferred to the peer device every 10 milliseconds.
It is recommended to run this sample together with the :ref:`Bluetooth: Peripheral ISO <peripheral_iso>` sample.
To run the sample with an encrypted isochronous channel, enable :kconfig:option:`CONFIG_BT_SMP`.
Requirements
************
* BlueZ running on the host, or
* A board with Bluetooth Low Energy 5.2 support
* A Bluetooth Controller and board that supports setting
:kconfig:option:`CONFIG_BT_CTLR_CENTRAL_ISO`.
Building and Running
********************
This sample can be found under :zephyr_file:`samples/bluetooth/central_iso` in
