Detailed Description

Reliable message sending for the access layer.

Function Documentation

void access_reliable_cancel_all ( void )

Cancels all ongoing transfers.

Warning: This will not notify the about the canceled transfer. Thus calling this function in the middle of a reliable transfer may cause unexpected behavior for the affected models.

uint32_t access_model_reliable_publish ( const access_reliable_t * p_reliable )

Starts publishing a reliable message.

Parameters

[in] p_reliable Reliable message parameter structure pointer.

Return values

NRF_SUCCESS	Successfully started the reliable message publication.
NRF_ERROR_NULL	NULL pointer given to function.
NRF_ERROR_NO_MEM	No memory available to send the message at this point.
NRF_ERROR_NOT_FOUND	Invalid model handle or model not bound to element.
NRF_ERROR_INVALID_PARAM	Model not bound to application key, publish address not set or wrong opcode format.
NRF_ERROR_INVALID_STATE	Message already scheduled for a reliable transfer.
NRF_ERROR_INVALID_LENGTH	Attempted to send message larger than ACCESS_MESSAGE_LENGTH_MAX.

uint32_t access_model_reliable_cancel ( access_model_handle_t model_handle )

Cancels an ongoing reliable message.

Parameters

[in] model_handle Access layer model handle that owns the transfer.

Return values

NRF_SUCCESS	Successfully canceled the reliable message.
NRF_ERROR_NOT_FOUND	No active reliable message for given handle.
NRF_ERROR_NOT_FOUND	Invalid model handle or model not bound to element.

void access_reliable_message_rx_cb	(	access_model_handle_t	model_handle,
		const access_message_rx_t *	p_message,
		void *	p_args
	)

Callback called by access layer when a model receives a message.

Parameters

[in]	model_handle	Model handle that received the message
[in]	p_message	Message pointer.
[in]	p_args	Generic argument pointer for the model.

bool access_reliable_model_is_free ( access_model_handle_t model_handle )

Checks if the model context for the given model handle is free for acknowledged message publishing.

Parameters

[in] model_handle Model handle of the model

Return values

True	If the model context is free for sending new acknowledged message.
False	If the model context is busy.
