(Multi Channel) Association#

CC Association and CC Multi Channel Association enable application level control of other devices.

For instance, a wall switch can control an LED bulb if an association to the LED bulb is created in the wall switch. Another example could be a motion sensor that turns on an LED bulb when motion is detected. Such associations can be created using either Association Set or Multi Channel Association Set.

Both CCs share a common module that stores the actual associations.

The specifications of CC Association and CC Multi Channel Association can be found in https://github.com/Z-Wave-Alliance/AWG/tree/main/source/management_command_classes/command_class_definitions

a transmission. It places a destination_node_list into the system.

AssociationGetBitAdressingDestination#

bool AssociationGetBitAdressingDestination (destination_info_t ** ppNodeList, uint8_t * pListLength, destination_info_t * pNode)

Outputs a node where associations to multiple endpoints of that node exist.

Parameters
[inout]ppNodeList

- Address of pointer to an element in the node list. The pointer will be updated as this function travels through the node list.

[inout]pListLength

- Pointer to length of the node list. The value will be updated by this function.

[out]pNode

- Address of the memory to where the node is written.

The pNode [OUT] (list) will contain all the endpoints using bit addressing, for endpoints equal or less than 7.

Operation: For the first encounter of a nodeID and an endpoint, this function will search for the same nodeID and add their endpoints to the endpoint-field as bit-flags. First time this function encounters a node without a valid endpoint for bit-addressing, it will terminate and return false because the list is sorted.

If there are zero nodes with multiple endpoints associated, the function will return false and write NULL to the pointer returned, pNode.

If further nodes with multiple endpoints associated exist after the initial list is created, the function will return true and indicate that this function is not finished.

If the function returns true, the invoker must invoke the function again to get the next node.

If there are no more nodes with multiple endpoints, the function will return false, as this function is only designed to return node-destinations with endpoints.

Example with 6 associations in total: (This is a pre-sorted list in accordance to requirements of this function!) 3.1 3.2 4.1 4.2 5.1 6.0

destination_info_t * pNodeList    // Must point to the first node in an association group.
uint8_t              listLength;  // Must be set to the length of the node list.
destination_info_t   node;
bool                 moreNodes;

moreNodes = AssociationGetBitAdressingDestination(&pNodeList, &listLength, &node);
// moreNodes is TRUE. (4.1 is still showing endpoint destination)
// pNodeList now points to node 4 endpoint 1.
// listLength now equals 4. (the two from the top with endpoints are removed from list)
// Bit-addressing is set to TRUE. (because 3.1 and 3.2 are bit-addressed)
// --> The prepared node contains the first nodeID (3) including the two endpoints as bit addressing.

moreNodes = AssociationGetBitAdressingDestination(&pNodeList, &listLength, &node);
// moreNodes is TRUE. (5.1 is still showing endpoint destination)
// pNodeList now points to node 5 endpoint 1.
// listLength now equals 2. (the four destinations from the top with endpoints are removed from list)
// Bit-addressing is set to TRUE. (because 4.1 and 4.2 are bit-addressed)
// --> The prepared node contains the second nodeID (4) including the two endpoints as bit addressing.

moreNodes = AssociationGetBitAdressingDestination(&pNodeList, &listLength, &node);
// moreNodes is FALSE. (6.0 is not having an endpoint destination)
// pNodeList now points to node 6 with no endpoints.
// listLength now equals 2. (the four destinations from the top remain the only removed from list)
// Bit-addressing is set to FALSE. (5.1 was the only endpoint destination of nodeID 5)
// // --> The prepared node is not good for multichannel TX with bit-addressing. This terminates multichannel TX.

// The nodeID 6 destination is not processed for multichannel transmissions due to how the list is sorted!

Returns

  • Returns true if this function needs to be called again for a different nodeID with endpoints, otherwise false.

AssociationGetSinglecastNodeCount#

uint32_t AssociationGetSinglecastNodeCount (void )

Returns the number of associations after the bit addressing destinations are removed.

Parameters
N/A

This function MUST be invoked AFTER AssociationGetBitAdressingDestination() has returned false.

Returns

  • Returns the number of remaining nodes when there are no more bit addressing nodes.

AssociationGetNextSinglecastDestination#

destination_info_t * AssociationGetNextSinglecastDestination (void )

Returns the address of the next association like an iterator.

Parameters
N/A

This function needs to know beforehand how many items it needs to iterate through.

If the number of iterations are more than totalNodeCount, there will be repeated return of the same item. If the number of iterations are less than totalNodeCount, it will impact the next transmission using this iterator.

AssociationGetDestinationInit() MUST have been invoked before this function.

This function must be invoked only AFTER AssociationGetBitAdressingDestination() has returned false.

Continuously invoking this function will return the next association. If there are no more associations in the group, the first one in the same group will be returned and so forth.

If the group is empty, the function will ASSERT.

Returns

  • Address of an association.
