Software stuck at "ble_stack_init()?

[dnguyen2019]

Do you why I could not pass the "ble_stack_init()? I did download softdevice from 0x0000-0x26000 and Application from 0x2600

int main(void)
{
// Initialize.
log_init();
leds_init();
timers_init();
buttons_init();
power_management_init();
ble_stack_init();
gap_params_init();
gatt_init();
services_init();
advertising_init();
conn_params_init();

Are you using the nRF52810 development kit or your own custom board?

You may want to configure your SoftDevice to use RC as the source for the low frequency clock. See if changing to these settings in the sdk_config file help. They should be in the SoftDevice clock configuration section.

NRF_SDH_CLOCK_LF_SRC 0

NRF_SDH_CLOCK_LF_RC_CTIV 16

NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2

NRF_SDH_CLOCK_LF_ACCURACY 1

Thanks, it works

Is there reference document for that RC as the source for the low frequency clock so if same problem comes for the other board i can configure.?
How we can calculate that particular values..?
If i am using NRF51822 ic, for that it is different..?

Waiting for your reply..

Regards,

Rohit

If you don't have an external crystal on the board, then you'd be using the internal RC source for the low frequency clock. If you had an external crystal, you should be using that.

Thanks!

My real product board does not have external crystal. Is is internal RC source working fine? If it's not then we need to add the external crystal?

The internal RC is not as accurate as a crystal.

This can have an impact on power consumption.
