| Requirements | ||||||
| ************ | ||||||
|
|
||||||
| The sample supports the following development kits: | ||||||
|
|
||||||
| .. table-from-sample-yaml:: | ||||||
|
|
||||||
| You can use any combination of the development kits mentioned above in your testing setup. | ||||||
|
|
||||||
| Additionally, the sample requires a connection to a computer with a serial terminal for each of the development kits. | ||||||
|
|
||||||
| Overview | ||||||
| ******** | ||||||
|
|
||||||
| When connected, the peripheral cycles through predefined host channel maps, changing every five seconds. | ||||||

| The central enables channel classification reporting using :c:func:`hci_vs_sdc_channel_reporting_enable` and handles the received reports in a local HCI VS event callback. | ||||||

| Testing | ||||||
| ======= | ||||||
|
|
||||||
| After programming the sample to both development kits, test it by performing the following steps: | ||||||
|
|
||||||
| 1. Connect to both kits with a terminal emulator (for example, the `Serial Terminal app`_). | ||||||
| See :ref:`test_and_optimize` for the required settings and steps. | ||||||
| #. Reset both kits. | ||||||
| #. In one of the terminal emulators, type ``c`` to start the application on the connected board in the central role. | ||||||
| #. In the other terminal emulator, type ``p`` to start the application in the peripheral role. | ||||||
| #. Observe that the kits establish a connection. | ||||||
| #. On the peripheral, observe a new channel map printed every five seconds. | ||||||
| #. On the central, observe matching channel maps applied from the received classification reports. | ||||||
