Variables#

EmberAssumeTrustCenterConcentratorType
emberAssumedTrustCenterConcentratorType

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 to emberAssumedTrustCenterConcentratorType.

Functions#

EmberStatus
emberSetConcentrator(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:

uint8_t
emberGetSourceRouteTableFilledSize(void)

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

uint8_t
emberGetSourceRouteTableTotalSize(void)

Return the size of the source route table.

uint8_t
emberGetSourceRouteOverhead(EmberNodeId 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.

uint32_t
emberSetSourceRouteDiscoveryMode(EmberSourceRouteDiscoveryMode mode)

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

void
emberConcentratorStartDiscovery(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 emberConcentratorStopDiscovery().

void
emberConcentratorStopDiscovery(void)

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

void
emberConcentratorNoteDeliveryFailure(EmberOutgoingMessageType type, EmberStatus status)

Legacy API. Notes when a packet fails to deliver.

void
emberConcentratorNoteRouteError(EmberStatus status, EmberNodeId nodeId)

Legacy API. Notes when a route error has occurred.
