Function Documentation

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

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

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 handler is called.
[in]	p_file_name	Pointer to the file name.

uint32_t bp_only_tx_calib_resp_transmit	(	bool	calibration_success,
		uint32_t	calibration_data
	)

Function for preparing and queueing calibration response message ready for transmission.

Response message is delivered to the ANT stack for transmission upon receiving EVENT_TX.

Parameters

[in]	calibration_success	True for calibration response success.
[in]	calibration_data	Signed 16-bit calibration data for the response message.

Returns: NRF_SUCCESS.

< Calibration response success status code in the calibration response main data page.

< Calibration response failure status code in the calibration response main data page.

< Index of the calibration data LSB field in the calibration response main data page.

< Get low byte of a uint16_t.

< Index of the calibration data MSB field in the calibration response main data page.

< Get high byte of a uint16_t.

uint32_t bp_only_tx_channel_event_handle	(	uint32_t	event,
		uint8_t const *	p_event_message_buffer,
		antplus_event_return_t *	p_event_return
	)

Function for processing received ANT channel event message.

Parameters

[in]	event	ANT event received.
[in]	p_event_message_buffer	ANT event message buffer.
[out]	p_event_return	Output data from the profile.

Returns: ant_broadcast_message_tx API return code, NRF_SUCCESS for success.

uint32_t bp_only_tx_initialize ( void )

Function for initializing the module.
