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

Can you share more details on what the application is doing here. What PHY are you scanning on here? Because the 3.4mA refers to when using 1Mbps. It's closer to the current consumption you would see when scanning on 2Mbps. Can you upload the .ppk file here (in a .zip) so we can review it to make sure it looks correct.

Best regards,

Simon

Upload the test program (based on samples/scan_adv) and the PPK2 file.

Has there been any progress?

[Simonr]

Please reply the questions I asked in my previous reply and upload the .ppk trace for our review. Without it it's very hard to move forward.

Best regards,

Simon

Is the information I uploaded earlier insufficient?

The scan_adv sample assumes a 1Mbps reception speed.

I have also uploaded the PPK2 file.

Hello,

I am not able to see the attached .ppk file here. Where has it been attached? The screenshot you have provided is unfortunately not sufficient enough. Can you please make sure that the .zip file is attached here for our review?

Best Regards,
