How long is between POWER-ON and broadcasting on NRF52832?

[George]

Hello    the time I  have measured  from  POWER-ON  to  begin broadcasting is 360ms  ,but  isn't it too long?      Platform NRF52832           SDK12.2.0

Hi,

I'm guessing you are using a 32 kHz crystal oscillator which has a typical startup time of ~250ms. The actual startup time varies with load capacitance etc. and 360 ms is normal. 

If you need faster startup times, you can force the Softdevice to use the internal RC oscillator instead which is able to start much faster, but uses more current.

Tank you very much! you are right ,I have seen the datasheet that says  setup time is about 300ms or less!

Happy to help!
