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 Bluetooth: Peripheral ISO sample.
To run the sample with an encrypted isochronous channel, enable 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
CONFIG_BT_CTLR_CENTRAL_ISO.
