Any nrf51 sample that consumes less than 0,500 mA?

[Alex Co]

Hi I am trying to optimize my nrf51 app for low power. However I can just reach 0,500mA when just advertising (advertisement only is ok for me). Do you know or do you have any sample that consumes less than that?

Thanks a lot

Did you make sure to point to the correct softDevice headers and take into account the increased size of the S130 over the S110? You should be able to debug the application and see if you enter main at all or if its some of the softdevice initialization functions that are asserting. Are you using Keil or GCC?

The ble_app_beacon example in SDK v12.3.0 use almost the entire advertisment packet, i.e. close to 30bytes with an advertisement interval of 100ms. So unless you're using a much lower connection interval then this should be comparable to what you're seeing. 

Best regards

Usually when I am trying a new sdk I simple open ble beacon example, compile it and burn using stlink

I am using GCC

My app is advertising in periods of 10 seconds...

Below is a screenshot from the PPK application in our nRF Connect for Desktop tool. It shows the average and peak current consumption of the ble_app_beacon example from SDK v12.3.0 using an advertisement interval of 10seconds, which gives you an average current consumption of about 5.7uA.
