3. Receive data packet.
4. Validate data packet.
5. Write Data packet to NVM.
6. If not finished - Wait for next packet.
7. Receive stop data packet.
8. Activate Image, boot application.

Macro Definition Documentation

#define BOOTLOADER_BUTTON_PIN   BUTTON7

Button used to enter SW update mode.

#define APP_GPIOTE_MAX_USERS   2

Number of GPIOTE users in total. Used by button module and dfu_transport_serial module (flow control).

#define APP_TIMER_PRESCALER   0

Value of the RTC1 PRESCALER register.

#define APP_TIMER_MAX_TIMERS   3

Maximum number of simultaneously created timers.

#define APP_TIMER_OP_QUEUE_SIZE   4

Size of timer operation queues.

#define BUTTON_DETECTION_DELAY   APP_TIMER_TICKS(50, APP_TIMER_PRESCALER)

Delay from a GPIOTE event until a button is reported as pushed (in number of timer ticks).

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 leds_init ( void  )

static void leds_off ( void  )

static

Clears all LEDs used by the application.

static void timers_init ( void  )

static
