Thanks. It's OK now. There's something wrong with the way I give the low level. Besides, I found that remove advertising_init() would be better.

I would recommend getting a Power Profiling Kit for more detailed current measurements. Could you please upload your entire application project for me to check the current consumption and debug this issue?

Hi Jørgen,

I haven't done anything else between stop and start advertising. I refer to the BSP module and I start or stop advertising in the bsp_event_handler function. I use a multimeter to measure the current consution.Since I use 1s advertising interval, I could see that it's about 2uA when it doesn't advertise.

When I stop advertising, the current is normal and it's 2.1uA.

Best regards.

Hi,

Your code to stop and start advertising looks OK. Are you doing anything else between stop and start (i.e. enable some other peripherals that can draw current)?What is the current draw on first run? How do you measure the current consumption?

Best regards.
