sl_zigbee_set_concentrator#

sl_status_t sl_zigbee_set_concentrator (bool on, uint16_t concentratorTypeParam, uint16_t minTime, uint16_t maxTime, uint8_t routeErrorThresholdParam, uint8_t deliveryFailureThresholdParam, uint8_t maxHopsParam)

initializing the node to act as a concentrator with:

@params discovery mode on/off concentratorTypeParam min time between MTORRs max time between MTORRs threshodl to react to route error message threshodl to react to delivery failures max number of hops for MTORR

sl_zigbee_get_source_route_table_filled_size#

uint8_t sl_zigbee_get_source_route_table_filled_size (void )

Return the number of used entries in the source route table.

sl_zigbee_get_source_route_table_total_size#

uint8_t sl_zigbee_get_source_route_table_total_size (void )

Return the size of the source route table.

sl_zigbee_get_source_route_overhead#

uint8_t sl_zigbee_get_source_route_overhead (sl_802154_short_addr_t destination)

Returns the number of bytes needed in a packet for source routing. Since each hop consumes 2 bytes in the packet, this routine calculates the total number of bytes needed based on number of hops to reach the destination.

Returns

• uint8_t The number of bytes needed for source routing in a packet or SL_ZIGBEE_SOURCE_ROUTE_OVERHEAD_UNKNOWN (no source route overhead).

sl_zigbee_set_source_route_discovery_mode#

uint32_t sl_zigbee_set_source_route_discovery_mode (sl_zigbee_source_route_discovery_mode_t mode)

Set source route discovery mode(MTORR scheduling mode) to on/off/reschedule.

@params: mode: SL_ZIGBEE_SOURCE_ROUTE_DISCOVERY_OFF = 0x00, SL_ZIGBEE_SOURCE_ROUTE_DISCOVERY_ON = 0x01, SL_ZIGBEE_SOURCE_ROUTE_DISCOVERY_RESCHEDULE = 0x02,

sl_zigbee_concentrator_start_discovery#

void sl_zigbee_concentrator_start_discovery (void )

Legacy API Starts periodic many-to-one route discovery. Periodic discovery is started by default on bootup, but this function may be used if discovery has been stopped by a call to sl_zigbee_concentrator_stop_discovery().

sl_zigbee_concentrator_stop_discovery#

void sl_zigbee_concentrator_stop_discovery (void )

Legacy API. Stops periodic many-to-one route discovery.

sl_zigbee_concentrator_note_delivery_failure#

void sl_zigbee_concentrator_note_delivery_failure (sl_zigbee_outgoing_message_type_t type, sl_status_t status)

Legacy API. Notes when a packet fails to deliver.

sl_zigbee_concentrator_note_route_error#

void sl_zigbee_concentrator_note_route_error (sl_status_t status, sl_802154_short_addr_t nodeId)

Legacy API. Notes when a route error has occurred.

sl_zigbee_send_many_to_one_route_request#

sl_status_t sl_zigbee_send_many_to_one_route_request (uint16_t concentratorType, uint8_t radius)

Send a route request packet that creates routes from every node in the network back to this node.

This function should be called by an application that wants to communicate with many nodes, for example, a gateway, central monitor, or controller. A device using this function was referred to as an "aggregator" in EmberZNet 2.x and earlier, and is referred to as a "concentrator" in the ZigBee specification and EmberZNet 3.

This function enables large scale networks because the other devices do not have to individually perform bandwidth-intensive route discoveries. Instead, when a remote node sends an APS unicast to a concentrator, its network layer automatically delivers a special route record packet first, which lists the network IDs of all intermediate relays. The concentrator can then use source routing to send outbound APS unicasts. (A source routed message is one in which the entire route is listed in the network layer header.) This allows the concentrator to communicate with thousands of devices without requiring large route tables on neighboring nodes.

This function is only available in ZigBee Pro (stack profile 2), and cannot be called on end devices. Any router can be a concentrator (not just the coordinator), and there can be multiple concentrators on a network.

Note that a concentrator does not automatically obtain routes to all network nodes after calling this function. Remote applications must first initiate an inbound APS unicast.

Many-to-one routes are not repaired automatically. Instead, the concentrator application must call this function to rediscover the routes as necessary, for example, upon failure of a retried APS message. This is necessary because there is no scalable one-size-fits-all route repair strategy. A common and recommended strategy is for the concentrator application to refresh the routes by calling this function periodically.

Returns

• ::SL_STATUS_OK if the route request was successfully submitted to the transmit queue, and ::SL_STATUS_FAIL otherwise.

sl_zigbee_get_source_route_table_entry#

sl_status_t sl_zigbee_get_source_route_table_entry (uint8_t index, sl_802154_short_addr_t * destination, uint8_t * closerIndex)

Return the source route table entry fields.

sl_zigbee_get_assumed_trust_center_concentrator_type#

sl_zigbee_assume_trust_center_concentrator_type_t sl_zigbee_get_assumed_trust_center_concentrator_type (void )

To configure non trust center node to assume a concentrator type of the trust center it join to, until it receive many-to-one route request from the trust center. For the trust center node, concentrator type is configured from the concentrator plugin. The stack by default assumes trust center be a low RAM concentrator that make other devices send route record to the trust center even without receiving a many-to-one route request. The assumed concentrator type can be changed by setting appropriate config value with sl_zigbee_set_assumed_trust_center_concentrator_type().

sl_zigbee_set_assumed_trust_center_concentrator_type#

void sl_zigbee_set_assumed_trust_center_concentrator_type (sl_zigbee_assume_trust_center_concentrator_type_t type)
