Da14585 power consumption problem

Hi yekun,

Thanks for your question. Can you please indicate if you have a custom board, or you are using any of our DKs? In second case, what is the DK that you are using and how you are measuring the sleep current?

Additionally, can you clarify if the device is advertising while measuring the power consumption?

Generally, the device goes into sleep mode (extended in your case) between advertising or connection intervals.

Please check the following tutorial for measuring the sleep mode current consumption :

http://lpccs-docs.dialog-semiconductor.com/DA14531_Sleep_Mode+/extsleep_config.html

The second is for DA14531 but it can be used for the DA14585/6, as they have common SDK6.0.14.

Keep in mind that if you have the SPI Flash attached the power consumption will be increased - so if you have jumpers you should removed the or put the flash in power down mode.

Hi yekun,

Apologies for my late response. Do you have the SPI flash attached while measuring the sleep currents? Did you follow the suggested tutorial?

Thanks, PM_Dialog
