Hello, I am usering nrf52840, now i am testing the current. i found that the current is 40uA in 0dBm while 201uA in 8dBm. maybe it is abnormal in 8dBm, what can i do to check it?

Hi
This seems strange indeed. You can check if this is an expected current by entering your parameters in our Online Power Profiler and test changing the various TX power options. How exactly do you measure the current on your board? Are you using a development kit or a custom board?
Best regards,

No, we are using a custom board instead of the development kit. we did more test on this board, this is the test data:
Sleep Mode(call sd_power_system_off): 0.64uA
System on(call sd_app_evt_wait): 3.04uA
when I turn on advertising, it is 22uA while 13uA according the Online Power Profiler.
I think the advertising is consuming more current, is there any way to reduce the current of advertising ?
It is 22uA while 13uA according the Online Power Profiler. (0dBm)
