How to reduce the power consumption of nrf54l15

[Ethan330]

The broadcast interval is 2s, and the power consumption is 7ua on the DK board; On this basis, the power consumption when using an external low-speed crystal oscillator is 8.8ua.

What else can I do to reduce power consumption?

I still want to try turning off GPOTE, but the software compilation failed. Please tell me how to turn off GPOTE and whether it will reduce power consumption。

Software version: v2.9.1; sample：Google locator tag。

This is the version I just updated, and using v2.8.0 seems to have higher power consumption. I don't understand why.

Hi,

 

Are you using the nRF54L15-DK for testing? If yes, then the default voltage is 1.8V.

If you plot in 2 seconds adv. interval with 20 bytes of payload, and VDD=1.8V here:

 Online Power Profiler for Bluetooth LE 

 

Depending on the size of the advertising payload, you should expect to see from 7 to 9.5 uA.

 

Kind regards,

Håkon

Yes, I tested it using the nRF54L15-DKboard; But I am using a power monitor that supplies 3V power to the board.

I used the "Online Power Profiler for Bluetooth LE" for power consumption prediction, with a broadcast interval of 1.2s and a power consumption pre calculation of 8.7ua. However, the actual power consumption I tested with the DK board was 10.14ua.  the size of the advertising payload is 20 bytes。The test results are shown in the picture below：

So I still want to ask if there are any ways to reduce power consumption？

and How to close the GPIOTE?

I think it's the useful document, for your reference.
