Detailed Description

When the application is booting, LED0 and LED1 are turned on. Once the SoftDevice is enabled, LED0 and LED1 are turned off to indicate the system is ready.

The example uses wildcard connection, which implies that it will connect to the nearest broadcasting ANT device. Channel period is set to 4 Hz (8192). When a packet is received it will turn on LED0 for 20 milliseconds.

LED1 is turned on whenever the processor enters sleep state and turned off when woken up by an interrupt.

Function Documentation

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

Function for error handling, which is called when an error has occurred.

Parameters

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

static void ant_channel_rx_broadcast_setup ( void  )

static

The following commands are issued in this order:

• assign channel
• set channel ID
• open channel

static void channel_event_handle ( uint8_t *  p_event_message_buffer )

static

Parameters

[in]

p_event_message_buffer

The ANT event message buffer.

void PROTOCOL_EVENT_IRQHandler

(

void

)

Implemented to clear the pending flag when receiving an interrupt from the stack.

void softdevice_assert_callback	(	uint32_t	pc,
		uint16_t	line_num,
		const uint8_t *	p_file_name
	)

Parameters

[in]	pc	Value of the program counter.
[in]	line_num	Line number where the assert occurred.
[in]	p_file_name	Pointer to the file name.
