Is there a Zephyr example that uses BLE PHY CODED

[CktDesigner]

Subject pretty much says it all.   I'm looking for a Zephyr project example that uses PHY CODED.    I'm using the nRF52840 with NCS 2.0.2 in the vscode environment.    I have things working using normal BLE, but now want to extend the range...    I see a call to "bt_conn_le_phy_update()" is available, but haven't found documentation (or an example) that explains the context in which it is used.   Or is there a different way?

Thanks!

Thanks!

I was looking in zephyr/samples/bluetooth

Now I see the example in nrf/samples/bluetooth

Thanks again...
