Non-Cluster Callbacks

Zigbee Application Framework API Reference > Application Framework Callback Interface

Add To Current App Tasks.

This function is only useful to sleepy end devices. This function will note the passed item as part of a set of tasks the application has outstanding (e.g. message sent requiring APS acknwoledgement). This will affect how the application behaves with regard to sleeping and polling. Until the outstanding task is completed, the device may poll more frequently and sleep less often.

Parameters

tasks

Ver.: always

Allow Network Write Attribute.

This function is called by the application framework before it writes an attribute in response to a write attribute request from an external device. The value passed into this callback is the value to which the attribute is to be set by the framework. Example: In mirroring simple metering data on an Energy Services Interface (ESI) (formerly called Energy Service Portal (ESP) in SE 1.0).), a mirrored simple meter needs to write read-only attributes on its mirror. The-meter-mirror sample application, located in app/framework/sample-apps, uses this callback to allow the mirrored device to write simple metering attributes on the mirror regardless of the fact that most simple metering attributes are defined as read-only by the ZigBee specification. Note: The ZCL specification does not (as of this writing) specify any permission-level security for writing writeable attributes. As far as the ZCL specification is concerned, if an attribute is writeable, any device that has a link key for the device should be able to write that attribute. Furthermore if an attribute is read only, it should not be written over the air. Thus, if you implement permissions for writing attributes as a feature, you MAY be operating outside the specification. This is unlikely to be a problem for writing read-only attributes, but it may be a problem for attributes that are writeable according to the specification but restricted by the application implementing this callback.

External Attribute Read.

Like emberAfExternalAttributeWriteCallback above, this function is called when the framework needs to read an attribute that is not stored within the Application Framework's data structures. All of the important information about the attribute itself is passed as a pointer to an EmberAfAttributeMetadata struct, which is stored within the application and used to manage the attribute. A complete description of the EmberAfAttributeMetadata struct is provided in app/framework/include/af-types.h This function assumes that the application is able to read the attribute, write it into the passed buffer, and return immediately. Any attributes that require a state machine for reading and writing are not really candidates for externalization at the present time. The Application Framework does not currently include a state machine for reading or writing attributes that must take place across a series of application ticks. Attributes that cannot be read in a timely manner should be stored within the Application Framework and updated occasionally by the application code from within the emberAfMainTickCallback. If the application was successfully able to read the attribute and write it into the passed buffer, it should return a value of EMBER_ZCL_STATUS_SUCCESS. Ensure that the size of the externally managed attribute value is smaller than what the buffer can hold. In the case of a buffer overflow throw an appropriate error such as EMBER_ZCL_STATUS_INSUFFICIENT_SPACE. Any other return value indicates the application was not able to read the attribute.

Parameters

endpoint	Ver.: always
clusterId	Ver.: always
attributeMetadata	Ver.: always
manufacturerCode	Ver.: always
buffer	Ver.: always
maxReadLength	Ver.: always

External Attribute Write.

This function is called whenever the Application Framework needs to write an attribute which is not stored within the data structures of the Application Framework itself. One of the new features in Version 2 is the ability to store attributes outside the Framework. This is particularly useful for attributes that do not need to be stored because they can be read off the hardware when they are needed, or are stored in some central location used by many modules within the system. In this case, you can indicate that the attribute is stored externally. When the framework needs to write an external attribute, it makes a call to this callback. This callback is very useful for host micros which need to store attributes in persistent memory. Because each host micro (used with an Ember NCP) has its own type of persistent memory storage, the Application Framework does not include the ability to mark attributes as stored in flash the way that it does for Ember SoCs like the EM35x. On a host micro, any attributes that need to be stored in persistent memory should be marked as external and accessed through the external read and write callbacks. Any host code associated with the persistent storage should be implemented within this callback. All of the important information about the attribute itself is passed as a pointer to an EmberAfAttributeMetadata struct, which is stored within the application and used to manage the attribute. A complete description of the EmberAfAttributeMetadata struct is provided in app/framework/include/af-types.h . This function assumes that the application is able to write the attribute and return immediately. Any attributes that require a state machine for reading and writing are not candidates for externalization at the present time. The Application Framework does not currently include a state machine for reading or writing attributes that must take place across a series of application ticks. Attributes that cannot be written immediately should be stored within the Application Framework and updated occasionally by the application code from within the emberAfMainTickCallback. If the application was successfully able to write the attribute, it returns a value of EMBER_ZCL_STATUS_SUCCESS. Any other return value indicates the application was not able to write the attribute.

Parameters

endpoint	Ver.: always
clusterId	Ver.: always
attributeMetadata	Ver.: always
manufacturerCode	Ver.: always
buffer	Ver.: always

Find Unused Pan Id And Form.

This function is called by the framework to search for an unused PAN id and form a new network. The application should return EMBER_SUCCESS if the operation was initiated successfully.

Get Current App Tasks.

This function is only useful to sleepy end devices. This function will return the set of tasks the application has outstanding. These tasks affect how the application behaves with regard to sleeping and polling.

Get Current Poll Control.

This function will retrieve the current poll control that the system is using for the current network. This is determined by examining all the scheduled events and obtaining the most restrictive poll control context across all events. The most restrictive poll control is EMBER_AF_SHORT_POLL followed by EMBER_AF_LONG_POLL.

Get Current Poll Interval Ms.

This function is only useful to end devices. This function will return the current poll interval (in milliseconds) for the current network. This interval is the maximum amount of time a child is currently waiting between polls of its parent.

Get Current Poll Interval Qs.

This function is only useful to end devices. This function will return the current poll interval (in quarter seconds) for the current network. This interval is the maximum amount of time a child is currently waiting between polls of its parent.

Get Current Sleep Control.

This function will retrieve the current sleep control that the system is using. This is determined by examining all the scheduled events and obtaining the most restrictive sleep control context across all events. The most restrictive sleep control is EMBER_AF_STAY_AWAKE followed by EMBER_AF_OK_TO_SLEEP.

Get Current Time.

This callback is called when device attempts to get current time from the hardware. If this device has means to retrieve exact time, then this method should implement it. If the callback can't provide the exact time it should return 0 to indicate failure. Default action is to return 0, which indicates that device does not have access to real time.

Get Default Poll Control.

This function will retrieve the default poll control for the current network as previously set by emberAfSetDefaultPollControlCallback() . The default poll control will limit whether the network can long poll.

Get Default Sleep Control.

This function will retrieve the default sleep control the system is using as previously set by emberAfSetDefaultSleepControlCallback() . The default sleep control will limit whether the device can sleep.

Get Endpoint By Index.

Get the endpoint number based on the passed index. By default the framework handles this by managing endpoints based on the precompiled configuration defined in AppBuilder. This callback can override this behavior at runtime and provide additional endpoints or different data than the compiled values. If the index is overridden than the callback shall return true and set the endpointReturn parameter accordingly. A value of 0xFF means the endpoint doesn't exist at that index. Otherwise false must be returned by the callback and the default framework behavior will be executed. This is only applicable to the SOC devices.

Parameters

index	The index of the endpoint. Ver.: always
endpointReturn	The value of endpoint. Ver.: always

Get Endpoint Description.

This callback is called by the framework whenever it receives a ZDO request to enumerate the details about an endpoint. By default the framework provides the information based on the precompiled endpoint information as defined in AppBuilder. This callback can override that behavior at runtime and return different information. If the endpoint information is being overridden then the callback must return true. Otherwise it should return false, which allows the framework to perform its default behavior. This is only applicable to SOC devices.

Parameters

endpoint	The endpoint number that is being queried. Ver.: always
result	This is a pointer to a data structure where the endpoint information is written if the callback is providing the information. Ver.: always

Get Endpoint Info.

This function is a callback to an application implemented endpoint that operates outside the normal application framework. When the framework wishes to perform operations with that endpoint it uses this callback to retrieve the endpoint's information. If the endpoint exists and the application can provide data then true shall be returned. Otherwise the callback must return false.

Parameters

endpoint	The endpoint to retrieve data for. Ver.: always
returnNetworkIndex	The index corresponding to the ZigBee network the endpoint belongs to. If not using a multi-network device, 0 must be returned. Otherwise on a multi-network device the stack will switch to this network before sending the message. Ver.: always
returnEndpointInfo	A pointer to a data struct that will be written with information about the endpoint. Ver.: always

Get Form And Join Extended Pan Id.

This callback is called by the framework to get the extended PAN ID used by the current network for forming and joining. The extended PAN ID used for forming and joining is not necessarily the same extended PAN ID actually in use on the network.

Parameters

resultLocation

Get Wake Timeout Bitmask.

This function is only useful to sleepy end devices. This function will return the wake timeout bitmask for the current network. The bitmask determines which tasks will timeout automatically and which tasks require manual removal from the task list.

Get Wake Timeout Ms.

This function is only useful to sleepy end devices. This function will return the wake timeout (in milliseconds) for the current network. This timeout is the maximum amount of time a child will wait for a task in the wake bitmask to finish. While waiting, the device will short poll.

Get Wake Timeout Qs.

This function is only useful to sleepy end devices. This function will return the wake timeout (in quarter seconds) for the current network. This timeout is the maximum amount of time a child will wait for a task in the wake bitmask to finish. While waiting, the device will short poll.

Main Init.

This function is called from the application's main function. It gives the application a chance to do any initialization required at system startup. Any code that you would normally put into the top of the application's main() routine should be put into this function. This is called before the clusters, plugins, and the network are initialized so some functionality is not yet available. Note: No callback in the Application Framework is associated with resource cleanup. If you are implementing your application on a Unix host where resource cleanup is a consideration, we expect that you will use the standard Posix system calls, including the use of atexit() and handlers for signals such as SIGTERM, SIGINT, SIGCHLD, SIGPIPE and so on. If you use the signal() function to register your signal handler, please mind the returned value which may be an Application Framework function. If the return value is non-null, please make sure that you call the returned function from your handler to avoid negating the resource cleanup of the Application Framework itself.

Main Init.

This function is called when the application starts and can be used to perform any additional initialization required at system startup.

Main Start.

This function is called at the start of main after the HAL has been initialized. The standard main function arguments of argc and argv are passed in. However not all platforms have support for main() function arguments. Those that do not are passed NULL for argv, therefore argv should be checked for NULL before using it. If the callback determines that the program must exit, it should return true. The value returned by main() will be the value written to the returnCode pointer. Otherwise the callback should return false to let normal execution continue.

Parameters

returnCode	Ver.: always
argc	Ver.: always
argv	Ver.: always

Main Tick.

Whenever main application tick is called, this callback will be called at the end of the main tick execution.

Main Tick.

This function is called in each iteration of the main application loop and can be used to perform periodic functions. The frequency with which this function is called depends on how quickly the main loop runs. If the application blocks at any time during the main loop, this function will not be called until execution resumes.

Mark Buffers.

This function is called when the garbage collector runs. Any buffers held by the application must be marked.

Message Sent.

This function is called by the application framework from the message sent handler, when it is informed by the stack regarding the message sent status. All of the values passed to the emberMessageSentHandler are passed on to this callback. This provides an opportunity for the application to verify that its message has been sent successfully and take the appropriate action. This callback should return a bool value of true or false. A value of true indicates that the message sent notification has been handled and should not be handled by the application framework.

Parameters

type	Ver.: always
indexOrDestination	Ver.: always
apsFrame	Ver.: always
msgLen	Ver.: always
message	Ver.: always
status	Ver.: always

Ncp Init.

The function is always called twice when the NCP is initialized. In the first invocation, memoryAllocation will be true and the application should only issue EZSP commands that affect memory allocation on the NCP. For example, tables on the NCP can be resized in the first call. In the second invocation, memoryAllocation will be false and the application should only issue EZSP commands that do not affect memory allocation. For example, tables on the NCP can be populated in the second call. This callback is not called on SoCs.

Parameters

Outgoing Packet Filter.

** REQUIRES INCLUDING THE PACKET-HANDOFF PLUGIN **

 This is called by

the Packet Handoff plugin when the stack prepares to send a packet from one of the protocol layers specified in EmberZigbeePacketType .

 The

packetType argument is one of the values of the EmberZigbeePacketType enum. If the stack receives an 802.15.4 MAC beacon, it will call this function with the packetType argument set to EMBER_ZIGBEE_PACKET_TYPE_BEACON .

This function is called by the framework on SOC platforms when a remote node requests a partner link key exchange. The application should return EMBER_SUCCESS to accept the request or any other status to reject it. On network coprocessor platforms, this function will not be called because the NCP handles partner link key exchange requests based on the binding policy.

Parameters

partner

The EUI of the remote node. Ver.: always

Partner Link Key Exchange Response.

This function is called by the framework when a remote node requests a partner link key exchange. The application should return true to accept the request or false to reject it.

Pre Cli Send.

This function is called by the framework when it is about to pass a message constructed over CLI to the stack primitives for sending. If the function returns true it is assumed that the callback has consumed and processed the message. The framework will not do any further processing on the message.

If the function returns false then it is assumed that the callback has

not processed the message and the framework will continue to process accordingly.

Parameters

apsFrame	The structure containing the APS frame Ver.: always
source	Source Node Id Ver.: always
destination	Destintion Node Id Ver.: always
message	Pointer to the message payload Ver.: always
messageLength	Length of the message payload Ver.: always

Pre Command Received.

This callback is the second in the Application Framework's message processing chain. At this point in the processing of incoming over-the-air messages, the application has determined that the incoming message is a ZCL command. It parses enough of the message to populate an EmberAfClusterCommand struct. The Application Framework defines this struct value in a local scope to the command processing but also makes it available through a global pointer called emberAfCurrentCommand, in app/framework/util/util.c. When command processing is complete, this pointer is cleared.

Parameters

cmd	Ver.: always

Pre Message Received.

This callback is the first in the Application Framework's message processing chain. The Application Framework calls it when a message has been received over the air but has not yet been parsed by the ZCL command-handling code. If you wish to parse some messages that are completely outside the ZCL specification or are not handled by the Application Framework's command handling code, you should intercept them for parsing in this callback.

This callback returns a Boolean value indicating whether or not the message has been handled. If the callback returns a value of true, then the Application Framework assumes that the message has been handled and it does nothing else with it. If the callback returns a value of false, then the application framework continues to process the message as it would with any incoming message. Note: This callback receives a pointer to an incoming message struct. This struct allows the application framework to provide a unified interface between both Host devices, which receive their message through the ezspIncomingMessageHandler, and SoC devices, which receive their message through emberIncomingMessageHandler.

Parameters

incomingMessage

Ver.: always

Pre Message Send.

This function is called by the framework when it is about to pass a message to the stack primitives for sending. This message may or may not be ZCL, ZDO, or some other protocol. This is called prior to any ZigBee fragmentation that may be done. If the function returns true it is assumed the callback has consumed and processed the message. The callback must also set the EmberStatus status code to be passed back to the caller. The framework will do no further processing on the message. If the function returns false then it is assumed that the callback has not processed the mesasge and the framework will continue to process accordingly.

Parameters

messageStruct	The structure containing the parameters of the APS message to be sent. Ver.: always
status	A pointer to the status code value that will be returned to the caller. Ver.: always

Pre Ncp Reset.

This function will be called prior to the reset of the NCP by the host.

Pre ZDO Message Received.

Parameters

emberNodeId	Ver.: always
apsFrame	Ver.: always
message	Ver.: always
length	Ver.: always
