Is LFCLK enabled after zboss_start();? and after zboss_start_no_autostart()?

[Ignacio]

Hi,

I would like to know if the LFCLK is enabled after zboss_start(); and after zboss_start_no_autostart().

I would like to use an rtc event to trigger a PPI routine and this requires the LFCLK running while the device is in sleeping mode.

I have not found any info about how the zboss library handles the LFCLK. Neither any reference to any function to request to keep the  LFCLK running. Sorry if I missed any info.

Thanks for your help

Hi Armand,

No, LFCLK is not enabled/running after zboss_start(), but it's initialized by the application for use for in app_timer (timers_init()), which is used by zboss.

You can use the app_timer in the application as well, without any modifications, but you should not change the NRF_RTC1->CC[N] registers.

If you are not using the Softdevice you could also use RTC0.

Best regards,
