Low Power NRF52 Beacon

[Tejas]

Hi,

We are facing an issue related to battery life. We are using sdk 15 and SD S132(7.0.1) and we are able to archived 30uA current consumption, but we want it near to 5uA. We have already set NRF_LOG_ENABLED to 0 and use nrf_pwr_mgmt_run() in main loop. How to reduce more current consumption? Is there anything we can do to reduce the current consumption?

Thanks

Hi.

Hard to say what is causing your device to use more power than expected. Have you looked at our beacon example in the our SDK, and used that as a template for your beacon?

Are you running your application on a custom board or the development kit?

Hi,

Thanks for your response.

Yes, I have used beacon example from sdk as a template and running application on custom board. I have also tested same application on nrf52 dk, but getting same current consumption.

I have set the advertisement interval to 1000 ms and Tx power set to -12.

How to set the clock in sdkconfig.h for minimum power consumption for beacon application?

Or anything else that I have to change in sdkconfig.h ?

Have you tested the current consumption for the stock beacon example?

Best regards,
Joakim
