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 )

static

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 leds_init ( void )

static

Initializes all LEDs used by this application.

static void timers_init ( void )

static

Initializes the timer module. This creates and starts application timers.

static void gap_params_init ( void )

static

This function shall be used to setup all the necessary GAP (Generic Access Profile) parameters of the device. It also sets the permissions and appearance.

static void advertising_init ( void )

static

Encodes the required advertising data and passes it to the stack. Also builds a structure to be passed to the stack when starting advertising.

static void on_bps_evt	(	ble_bps_t *	p_bps,

static void on_conn_params_evt ( ble_conn_params_evt_t * p_evt )

static

This function will be called for all events in the Connection Parameters Module which are passed to the application.

Note: All this function does is to disconnect. This could have been done by simply setting the disconnect_on_fail configuration parameter, but instead we use the event handler mechanism to demonstrate its use.
