Does the BL54L15 support Direct Test Mode (DTM)?

Answer

Yes, the BL54L15 supports DTM. This is possible because the BL54L15 DVK is fully supported within the nRF Connect SDK and Zephyr, which means proper board DTS and Kconfig overlay files are available for enabling features such as DTM.

To use DTM or other board-specific functionality, you must add the correct overlays for the BL54L15 DVK to your project. Since the Ezurio DVK is virtually identical to the Nordic nRF54L15-DK, you can also use Nordic’s overlay files—just rename them accordingly to match the Ezurio board naming.
