54l15 BLE ADV signal not output after building and flashing appropriate FW

[Kenny Lee litepoint]

I have an nRF54l15-PDK dev board (brand new):

I did the following commands with the SDK v3.0.2. Building and Flashing went fine:

to build:

west build -b nrf54l15dk/nrf54l15/cpuapp nrf/samples/bluetooth/peripheral_lbs --pristine

to flash:

west flash

However, when trying to capture the ADV signals using and SA, none was found (see screenshot below, no signal were detected in a 200ms span):

I also have an nrf5340 dev board. When I did the same sequence, it works. I got a signals out of the antenna port (3 adv signals at 100ms interval,see screenshot below):

to build:

west build -b nrf5340dk/nrf5340/cpuapp nrf/samples/bluetooth/peripheral_lbs --pristine

to flash:

west flash

Is there a step I am missing for 54l15? For 5340, I must run an empty_app_core, prior to peripheral_lbs. Is it also necessary for 54l15?

-Thank you!

Thank you for posting the picture of your hardware.

PDK (Preview Development Kit) is not supported with NCSv3.0.2. Developing with nRF54L Series lists the DK versions supported.

I recommend purchasing a Development Kit that is supported by the later versions of NCS.

Since you have the PDK you could try the supported NCS version listed.
