nRF54L15 BLE RX current comsumption

[loquat]

I measured the power consumption of the BLE RX using the nRF54L15.(nRF54L15-DK v1.0.0)
3.0V operation
apps: scan_adv (delete advertising)
west build -b nrf54l15dk/nrf54l15/cpuapp
proj.conf
CONFIG_BT=y
CONFIG_BT_BROADCASTER=y
CONFIG_BT_OBSERVER=y
CONFIG_LOG=n
CONFIG_SERIAL=n

Result: The average current consumption was 3.73mA.
This is 330uA higher than the 3.4mA stated in the datasheet.
Is this correct behavior? Is further processing required to reduce it to 3.4mA?

Hi Emil and syuji

Thank you for your feedback. It seems erratum 20 mentions as part of the workaround that CONSTLAT should be triggered before enabling RX as well, but I agree that that could be updated to be reflected in the Conditions as well.

I will also reignite the internal discussion about following up this being stated in the nRF54L15 (and possibly nRF54LM20) datasheet. Thank you both for your insight and feedback here so far.

Best regards,

Simon

Thanks.

I have hopes for you.
