otNetDataPublishDnsSrpServiceAnycast#

void otNetDataPublishDnsSrpServiceAnycast (otInstance * aInstance, uint8_t aSequenceNUmber)

Requests "DNS/SRP Service Anycast Address" to be published in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

A call to this function will remove and replace any previous "DNS/SRP Service" entry that was being published (from earlier call to any of otNetDataPublishDnsSrpService{Type}() functions).

otNetDataPublishDnsSrpServiceUnicast#

void otNetDataPublishDnsSrpServiceUnicast (otInstance * aInstance, const otIp6Address * aAddress, uint16_t aPort)

Requests "DNS/SRP Service Unicast Address" to be published in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

A call to this function will remove and replace any previous "DNS/SRP Service" entry that was being published (from earlier call to any of otNetDataPublishDnsSrpService{Type}() functions).

Requests "DNS/SRP Service Unicast Address" to be published in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

A call to this function will remove and replace any previous "DNS/SRP Service" entry that was being published (from earlier call to any of otNetDataPublishDnsSrpService{Type}() functions).

Unlike otNetDataPublishDnsSrpServiceUnicast() which requires the published address to be given and includes the info in the Service TLV data, this function uses the device's mesh-local EID and includes the info in the Server TLV data.

otNetDataIsDnsSrpServiceAdded#

bool otNetDataIsDnsSrpServiceAdded (otInstance * aInstance)

Indicates whether or not currently the "DNS/SRP Service" entry is added to the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

otNetDataSetDnsSrpServicePublisherCallback#

void otNetDataSetDnsSrpServicePublisherCallback (otInstance * aInstance, otNetDataDnsSrpServicePublisherCallback aCallback, void * aContext)

Sets a callback for notifying when a published "DNS/SRP Service" is actually added to or removed from the Thread Network Data.

A subsequent call to this function replaces any previously set callback function.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

otNetDataUnpublishDnsSrpService#

void otNetDataUnpublishDnsSrpService (otInstance * aInstance)

Unpublishes any previously added DNS/SRP (Anycast or Unicast) Service entry from the Thread Network Data.

OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE must be enabled.

otNetDataPublishOnMeshPrefix#

otError otNetDataPublishOnMeshPrefix (otInstance * aInstance, const otBorderRouterConfig * aConfig)

Requests an on-mesh prefix to be published in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

Only stable entries can be published (i.e.,aConfig.mStable MUST be TRUE).

A subsequent call to this method will replace a previous request for the same prefix. In particular, if the new call only changes the flags (e.g., preference level) and the prefix is already added in the Network Data, the change to flags is immediately reflected in the Network Data. This ensures that existing entries in the Network Data are not abruptly removed. Note that a change in the preference level can potentially later cause the entry to be removed from the Network Data after determining there are other nodes that are publishing the same prefix with the same or higher preference.

otNetDataPublishExternalRoute#

otError otNetDataPublishExternalRoute (otInstance * aInstance, const otExternalRouteConfig * aConfig)

Requests an external route prefix to be published in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

Only stable entries can be published (i.e.,aConfig.mStable MUST be TRUE).

A subsequent call to this method will replace a previous request for the same prefix. In particular, if the new call only changes the flags (e.g., preference level) and the prefix is already added in the Network Data, the change to flags is immediately reflected in the Network Data. This ensures that existing entries in the Network Data are not abruptly removed. Note that a change in the preference level can potentially later cause the entry to be removed from the Network Data after determining there are other nodes that are publishing the same prefix with the same or higher preference.

otNetDataReplacePublishedExternalRoute#

otError otNetDataReplacePublishedExternalRoute (otInstance * aInstance, const otIp6Prefix * aPrefix, const otExternalRouteConfig * aConfig)

Replaces a previously published external route in the Thread Network Data.

Requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

If there is no previously published external route matching aPrefix, this function behaves similarly to otNetDataPublishExternalRoute(), i.e., it will start the process of publishing aConfig as an external route in the Thread Network Data.

If there is a previously published route entry matching aPrefix, it will be replaced with the new prefix from aConfig.

• If the aPrefix was already added in the Network Data, the change to the new prefix in aConfig is immediately reflected in the Network Data. This ensures that route entries in the Network Data are not abruptly removed and the transition from aPrefix to the new prefix is smooth.

• If the old published aPrefix was not added in the Network Data, it will be replaced with the new aConfig prefix but it will not be immediately added. Instead, it will start the process of publishing it in the Network Data (monitoring the Network Data to determine when/if to add the prefix, depending on the number of similar prefixes present in the Network Data).

otNetDataIsPrefixAdded#

bool otNetDataIsPrefixAdded (otInstance * aInstance, const otIp6Prefix * aPrefix)

Indicates whether or not currently a published prefix entry (on-mesh or external route) is added to the Thread Network Data.

otThreadGetTimeInQueueHistogram#

const uint32_t * otThreadGetTimeInQueueHistogram (otInstance * aInstance, uint16_t * aNumBins, uint32_t * aBinInterval)

Gets the time-in-queue histogram for messages in the TX queue.

Requires OPENTHREAD_CONFIG_TX_QUEUE_STATISTICS_ENABLE.

Histogram of the time-in-queue of messages in the transmit queue is collected. The time-in-queue is tracked for direct transmissions only and is measured as the duration from when a message is added to the transmit queue until it is passed to the MAC layer for transmission or dropped.

The histogram is returned as an array of uint32_t values with aNumBins entries. The first entry in the array (at index 0) represents the number of messages with a time-in-queue less than aBinInterval. The second entry represents the number of messages with a time-in-queue greater than or equal to aBinInterval, but less than 2 * aBinInterval. And so on. The last entry represents the number of messages with time-in-queue greater than or equal to (aNumBins - 1) * aBinInterval.

The collected statistics can be reset by calling otThreadResetTimeInQueueStat(). The histogram information is collected since the OpenThread instance was initialized or since the last time statistics collection was reset by calling the otThreadResetTimeInQueueStat().

Pointers aNumBins and aBinInterval MUST NOT be NULL.

Returns

• A pointer to an array of aNumBins entries representing the collected histogram info.

Requires OPENTHREAD_CONFIG_TX_QUEUE_STATISTICS_ENABLE.

The time-in-queue is tracked for direct transmissions only and is measured as the duration from when a message is added to the transmit queue until it is passed to the MAC layer for transmission or dropped.

The collected statistics can be reset by calling otThreadResetTimeInQueueStat().

Returns

• The maximum time-in-queue in milliseconds for all messages in the TX queue (so far).

otThreadResetTimeInQueueStat#

void otThreadResetTimeInQueueStat (otInstance * aInstance)

Resets the TX queue time-in-queue statistics.

Returns

• TRUE if an anycast locate request is currently in progress, FALSE otherwise.

otThreadSendAddressNotification#

void otThreadSendAddressNotification (otInstance * aInstance, otIp6Address * aDestination, otIp6Address * aTarget, otIp6InterfaceIdentifier * aMlIid)

Sends a Proactive Address Notification (ADDR_NTF.ntf) message.

Is only available when OPENTHREAD_CONFIG_REFERENCE_DEVICE_ENABLE is enabled.

otThreadSendProactiveBackboneNotification#

otError otThreadSendProactiveBackboneNotification (otInstance * aInstance, otIp6Address * aTarget, otIp6InterfaceIdentifier * aMlIid, uint32_t aTimeSinceLastTransaction)

It sends an Address Release if it's a router, or sets its child timeout to 0 if it's a child.

otConvertDurationInSecondsToString#

void otConvertDurationInSecondsToString (uint32_t aDuration, char * aBuffer, uint16_t aSize)

Converts an uint32_t duration (in seconds) to a human-readable string.

Requires OPENTHREAD_CONFIG_UPTIME_ENABLE to be enabled.

The string follows the format "<hh>:<mm>:<ss>" for hours, minutes, seconds (if duration is shorter than one day) or "<dd>d.<hh>:<mm>:<ss>" (if longer than a day).

If the resulting string does not fit in aBuffer (within its aSize characters), the string will be truncated but the outputted string is always null-terminated.
