Hi Hung,

Thank you for your reply. I will order a Sparkfun nrf52832 board to verify it is not hardware related to my custom board. If I'm sure it's not hardware related I will also post it on mbed forums.

Hi Melvin,

14uA is not the normal sleeping current of the nRF52 chip, there must be something else running. I would suggest you to post this on mbed forum as well. We are currently on reduced staff due to the holiday season, our expert in mbed is not available at the moment. We will try to get back to you when we have the full staff back.

Oh and I'm asking this question because it's a bit strange that the current consumption drops to ~3uA after the advertisement for a few ms and than goes to 14uA. The advertisment interval in this example is 2s.
