How to use clock RC \51422

[Linxi]

I intend to use RC oscillator instead of external crystal oscillator .

I modified code : from SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL); to SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, NULL);

The result is that my code can't run successfully. It seems that there is no clock source apply.

Please give me some tips ,thanks.

It should work fine to use the internal RC oscillator. When I test SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, NULL) with SDK 10, it works fine.

What does your application do? Do you see the same problem if you modify that line in one of the examples in the SDK?

Which version of the SDK do you use?

Okay, I see. Do you still have an external 16MHz clock on your PCB? (An external 16 MHz crystal is mandatory.)
