The HCI low power UART sample in the nRF Connect SDK can be used to implement a Bluetooth HCI controller using UART communication. The latest release should make this sample work on nRF54L15

To use this with Ubuntu, you would need to:Build and program the sample to your development kit.Connect the DK to your Ubuntu machine via USB. Use the BlueZ stack in Ubuntu to interact with the HCI controller.

nRF5x support within the Zephyr Project RTOS blogpost. It provides instructions on how to use BlueZ with a Zephyr HCI controller, including commands for attaching the controller and using btmgmt to interact with it.

For nrf54L there are not many official helper utilities yet, but we had quite few for nRF52 and nRF53 based products apart from nrfutil. You can see an external tool that is useful for power measurement extention with PPK2 works well with ubuntu.

Hi !

Thank you !

Do you have any tech info how-to connect DK via HCI/serial to Ubuntu ?

Could you point me to info about nrflike utility what is python based. I should evaluate it .

Hi,

[quote user=""]Does latest nRF52 Connect SDK have sample for HCI interface with Bluetooth Controller ?[/quote]

You should be able to use SDK/nrf/samples/bluetooth/hci_lpuart for this when you download the nrf connect sdk. Please read more about the build types that are supported for this.

[quote user=""]Does command line utility ( like nrfutil ) available in source code for Linux on ARM integration ?[/quote]

No, the sources are not public. The newer version of nrfutil that works with nRF54 devices is distributed as precompiled binaries that can be installed on Linux machines using python or manually.
