nRF54L15DK ChannelSounding Test

[Lee1823]

Hello,

I would like to use the official hci_uart sample to send Channel Sounding test-related HCI commands (specifically HCI_LE_CS_TEST and HCI_LE_CS_TEST_END) to the Nordic nRF54L15 DK. Could you please advise on the required configurations I need to implement for this?

Thank you for your assistance!

Hello,

1) You need to first enable Channel sounding in the controller when building hci_uart. This must be done via Kconfig:

west build -b nrf54l15dk/nrf54l15/cpuapp --pristine -- -DCONFIG_BT_CTLR_CHANNEL_SOUNDING=y

2) Ensure that the CS controller options are set as needed (this is optional):

BT_CTLR_CHANNEL_SOUNDING=y

BT_CTLR_SDC_CS_COUNT

BT_CTRL_SDC_CS_ROLE_*

BT_CTRL_SDC_CS_STEP_MODE3

3) Then you can flash the hci_uart image to your DK. After building, you can program the DK via west flash

4) You can then send CS test HCI commands over UART:

HCI_LE_CS_TEST

HCI_LE_CS_TEST_END

I recommend you to take a look at our following documentations: 

LE CS doc - Explains about Channel Sounding, which capabilities are supported, how its enabled with Kconfig.

Developing with CS - Lists Kconfig options for channel sounding

Testing CS implementation - Mentions using HCI UART sample
