Output HFCLK with PPI while SoftDevice is enabled

Hello,

have you called the function 'output_800KHz()' after ble stack function? For ble_app_interactive example, you can call the function ''output_800KHz()'' after ''ble_m_init()'' under the main function. It should work accordingly.

int main(void)
{
power_management_init();
log_init();
timer_init();
// Console start
cli_uart_cfg();
cli_uart_start();
#if NRF_MODULE_ENABLED(CLI_RTT)
cli_rtt_start();
#endif // CLI_RTT
ble_m_init();
output_800KHz();
peer_manager_init();
nfc_pairing_init();
#if NRF_MODULE_ENABLED(ADAFRUIT_SHIELD)
nfc_central_init();
#endif // ADAFRUIT_SHIELD
bond_get();

NRF_LOG_RAW_INFO("BLE app with command line interface example started.\r\n");
NRF_LOG_RAW_INFO("Press Tab to view all available commands.\r\n");

for (;;)
{
idle_state_handler();
}
}

Thanks.

Best Regards,

The project starts from ble_app_interactive example, but have many changes to support various peripherals outside the chip

(ble_cenrtral_and_peripheral -> experimental -> ble_app_interactive)

Thanks

There are two come snippets above.

The first one works when SD is not enabled.
The second one is adapted to use SD functions, but is basically the same code - it does NOT work when the SD is enabled.

I need any version/solution that works (output 800KHz on a SIO) while SD is running

Thanks

Hello,

Which example you are working on?

Thanks.
