Function Documentation

void app_error_handler	(	uint32_t	error_code,
		uint32_t	line_num,
		const uint8_t *	p_file_name
	)

Warning

This handler is an example only and does not fit a final product. You need to analyze how your product is supposed to react in case of error.

Parameters

[in]	error_code	Error code supplied to the handler.
[in]	line_num	Line number where the handler is called.
[in]	p_file_name	Pointer to the file name.

void assert_nrf_callback	(	uint16_t	line_num,
		const uint8_t *	p_file_name
	)

This function will be called in case of an assert in the SoftDevice.

Warning

This handler is an example only and does not fit a final product. You need to analyze how your product is supposed to react in case of Assert.

On assert from the SoftDevice, the system can only recover on reset.

Parameters

[in]	line_num	Line number of the failing ASSERT call.
[in]	file_name	File name of the failing ASSERT call.

static void battery_level_meas_timeout_handler ( void *  p_context )

This function will be called each time the battery level measurement timer expires.

Parameters

[in]

p_context

Pointer used for passing some arbitrary information (context) from the app_start_timer() call to the timeout handler.

static void heart_rate_meas_timeout_handler ( void *  p_context )

static

This function will be called each time the heart rate measurement timer expires. It will exclude RR Interval data from every third measurement.

Parameters

[in]

p_context

Pointer used for passing some arbitrary information (context) from the app_start_timer() call to the timeout handler.

static void rr_interval_timeout_handler ( void *  p_context )

static

This function will be called each time the RR interval timer expires.

Parameters

[in]

p_context

Pointer used for passing some arbitrary information (context) from the app_start_timer() call to the timeout handler.

static void sensor_contact_detected_timeout_handler ( void *  p_context )

p_context

Pointer used for passing some arbitrary information (context) from the app_start_timer() call to the timeout handler.

static void leds_init ( void  )

static

Initializes all LEDs used by this application.

p_evt

Event received from the Connection Parameters Module.

static void conn_params_error_handler ( uint32_t  nrf_error )

static

void hci_transport_timeout_handle

(

void *

p_context
