Detailed Description

For getting information about nodes of a ZigBee network via a ZigBee Device Object (ZDO). See zigbee-device-library.h and zigbee-device-common.h for source code.

The ZDO library provides functions that construct and send several common ZDO requests. It also provides a function for extracting the two addresses from a ZDO address response. The format of all the ZDO requests and responses that the stack supports is described in stack/include/zigbee-device-stack.h . Since the library doesn't handle all of these requests and responses, the application must construct any other requests it wishes to send and decode any other responses it wishes to receive.

The request sending functions do the following:

  1. Construct a correctly formatted payload buffer.
  2. Fill in the APS frame with the correct values.
  3. Send the message by calling either emberSendBroadcast() or emberSendUnicast() .

The result of the send is reported to the application as normal via emberMessageSentHandler() .

The following code shows an example of an application's use of emberSimpleDescriptorRequest() . The command interpreter would call this function and supply the arguments.

void sendSimpleDescriptorRequest(EmberCommandState *state)
{
EmberNodeId target = emberUnsignedCommandArgument (state, 0);
uint8_t targetEndpoint = emberUnsignedCommandArgument (state, 1);
if ( emberSimpleDescriptorRequest (target,
targetEndpoint,
EMBER_APS_OPTION_NONE ) != EMBER_SUCCESS ) {
emberSerialPrintf(SERIAL_PORT, "emberSimpleDescriptorRequest failed\r\n" );
}
}

The following code shows an example of an application's use of emberDecodeAddressResponse() .

void emberIncomingMessageHandler ( EmberIncomingMessageType type,
EmberApsFrame *apsFrame,
EmberMessageBuffer message)
{
if (apsFrame-> profileId == EMBER_ZDO_PROFILE_ID ) {
switch (apsFrame-> clusterId ) {
case NETWORK_ADDRESS_RESPONSE :
case IEEE_ADDRESS_RESPONSE :
{
EmberEUI64 eui64;
EmberNodeId nodeId = emberDecodeAddressResponse (message, eui64);
// Use nodeId and eui64 here.
break ;
}
default :
// Handle other incoming ZDO responses here.
}
} else {
// Handle incoming application messages here.
