Having trouble calling ble_stack_init in SDK 17.0.2 with s140 7.2.
The application compiles but hangs up on the error check after nrf_sdh_enable_request and outputs garbage characters to the debug terminal.
Looking further, I can see that sd_softdevice_enable is returning 0x1001 instead of NRF_SUCCESS but for some reason the nrf_sdh_enable_request doesn't seem to be returning this value and hence the error check just hangs.
The error returned by sd_softdevice_enable is confusing me as well. Looking at the docs, this seems to be because either there's a IRQ_PRIORITY violation, the SoftDevice is already initialized, or the LF_CLOCK source is incorrect. I've looked into all three of these scenarios and haven't come up with anything. All my IRQ_PRIORITIES in sdk_config are all set to 6, I've confirmed my LF_CLOCK source is correct, and despite my efforts I cannot seem to find how or why the SoftDevice may already be initialized before I call ble_stack_init().
I've even added a nrf_sdh_is_enabled function call just before the nrf_sdh_enable_request which I can see in the debugger returns as false. So I am totally at a loss.
Here's my main loop:
int main(void)
{
// Initialize.
log_init();
//NRF_LOG_INFO("Logs initialized");
timer_init();
leds_init();
saadc_init();
saadc_sampling_event_init();
saadc_sampling_event_enable();
buttons_init();
power_management_init();
ble_stack_init();
gatt_init();
peer_manager_init(true);
db_discovery_init();
lbs_c_init();
ble_conn_state_init();
scan_init();
scan_start();
// Start execution.
while (true)
{
if (NRF_LOG_PROCESS() == false)
{
idle_state_handle();
}
}
}
Any help would be appreciated,
Thanks,
Sam
