Using RTC with CGMS

Hi.

Which RTC are you using? RTC0 is blocked by the SoftDevice, but that is the one used in the example in the peripheral folder.

Best regards,

Andreas

Hi Andreas,

I'm using SDK 15.2.0. Yes Soft Device is in use, I'm looking at using RTC along with Bluetooth CGMS. The samples I am merging are .\RF5_SDK_15.2.0_9412b96\examples\ble_peripheral\experimental\ble_app_cgms and .\M\nRF5_SDK_15.2.0_9412b96\examples\peripheral\rtc. I'm suspecting? a conflict with LFCLK. We do not have an extermal OSC on the board, so I selected,

#define NRFX_CLOCK_CONFIG_LF_SRC 0,

#define CLOCK_CONFIG_LF_SRC 0, and

#define NRF_SDH_CLOCK_LF_SRC 0.

The ABORT is occurring right around setting the RTC prescale value. In the original RTC, prescale was 4095 and it appeared that the abort was in the comparison of prescale <= 4095. Changing the prescale value to 0x0FFF also aborted though.

Hi.

Which SDK and which example are you looking at?

Are you using the SoftDevice?

Best regards,

Andreas
