I haven't changed the macro value. Yes, i will go step by step and will check which thing is making it to return that error.

Thanks...!!!

If I copy your clock configurations it works on my side. I see that you have:

// <o> NRF_SDH_CLOCK_LF_ACCURACY  - External clock accuracy used in the LL to compute timing.
 
// <0=> NRF_CLOCK_LF_ACCURACY_250_PPM 
// <1=> NRF_CLOCK_LF_ACCURACY_500_PPM 
// <2=> NRF_CLOCK_LF_ACCURACY_150_PPM 
// <3=> NRF_CLOCK_LF_ACCURACY_100_PPM 
// <4=> NRF_CLOCK_LF_ACCURACY_75_PPM 
// <5=> NRF_CLOCK_LF_ACCURACY_50_PPM 
// <6=> NRF_CLOCK_LF_ACCURACY_30_PPM 
// <7=> NRF_CLOCK_LF_ACCURACY_20_PPM 
// <8=> NRF_CLOCK_LF_ACCURACY_10_PPM 
// <9=> NRF_CLOCK_LF_ACCURACY_5_PPM 
// <10=> NRF_CLOCK_LF_ACCURACY_2_PPM 
// <11=> NRF_CLOCK_LF_ACCURACY_1_PPM 

#ifndef NRF_SDH_CLOCK_LF_ACCURACY
#define NRF_SDH_CLOCK_LF_ACCURACY NRF_CLOCK_LF_ACCURACY_500_PPM
#endif

NRF_CLOCK_LF_ACCURACY_500_PPM is usually defined in nrf_sdm.h. Have you changed it there? (Line 209), or is it still 1?

If it is in fact 1, then there is something different. I believe you need to roll back and try to go step by step forward to see what change that made this return NRF_ERROR_INVALID_PARAM.

devzone.nordicsemi.com/.../0640.sdk_5F00_config.h

Please find the attached sdk_config.h file and let me know if any configuration change is required ?

Are you sure that you are not changing the CLOCK_CONFIG_LF_SRC instead of the NRF_SDH_CLOCK_LF_SRC?

Can you send me your sdk_config.h?

Hi Edvin,

Thank you for you reply.

I used the same configuration as mentioned in the thread, still it is throwing the error at sd_softdevice_enable function (returning NRF_ERROR_INVALID_PARAM). I am using SDK15.3.0

Anything that i am missing in clock configuration ?

Regards,

Nikhil

I don't know what SDK version you use, but if you recompile the entire project, then you should see a compiler warning saying:

Please select NRF_CLOCK_LF_ACCURACY_500_PPM when using NRF_CLOCK_LF_SRC_RC

This is because you don't have a clock with accuracy 20ppm when you use the RC Oscillator.

I would suggest to use the following combination if you are going to use the RC Oscillator:

#define NRF_SDH_CLOCK_LF_SRC 0
#define NRF_SDH_CLOCK_LF_RC_CTIV 16
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
#define NRF_SDH_CLOCK_LF_ACCURACY 1

Best regards,

Edvin
