( PH:0x05, SH:0x00 ) - Send ZCL Unicast Command
Overview
The Send ZCL Unicast command is sent by the Host to the Module in order to transmit a custom ZCL message to a target node. The command provides facilities for configuring the Encryption Level of the message, either with Network or Network + APS Encryption, as well as available Response Options, including custom sequence numbers, requiring an APS ACK or enabling processing of a corresponding response with a matching transaction sequence number.

Effect on Receipt
The Module will attempt to issue the ZCL message over the network. The status of the transmission and its assigned sequence number will be relayed to the Host via a ZCL Send Status command.
If the Host wishes to know whether the Destination Node has successfully received a message, it should enable reception of APS ACK status messages via the Response Options field. On reception the Module relays these messages to the Host as ZCL APS Ack commands.
If the given message is a request (e.g., Read Attribute Request, Add Group, etc.) and the Host expects a response, it should enable the option to receive a ZCL Response Received command, via the same field. On reception of a message with a matching sequence number, the Module will relay the response to the Host via the ZCL Response Received command. If no response is received within a given interval, the Module will instead issue a ZCL Response Timeout command to the Host.

( PH:0x05, SH:0x01 ) - Send ZCL Multicast Command
Overview
The Send ZCL Multicast command is sent by the Host to the Module in order to prompt the latter to multicast a ZCL Message to a select Group of target devices on the network.

( PH:0x05, SH:0x03 ) - ZCL Send Status Command
Overview
The ZCL Send Status message is sent by the Module to the Host after the transmission of a Send ZCL Unicast, Send ZCL Multicast or Send ZCL Broadcast. The message conveys the success or failure of the preceding transmission. If the Status indicates success, the message will also convey a value for the Transaction Sequence Number assigned to it.
Payload
Byte Index | Field Name | Notes |
|---|---|---|
0 | Status | 0x00 = Success, the message was successfully transmitted |
1 | Transaction Sequence Number | The ZCL Transaction Sequence Number assigned to this message, with a valid value in place only if the Status indicates Success. |
Effect on Receipt
No action is expected of the Host as the command is for notification purposes only. The Host may choose to display the Status in some manner, or it may also choose to re-send the message if the Status indicates an error occurred.
The Host also retains the option to store the Transaction Sequence Number associated with any outgoing message, such that it may match received ZCL Send Status messages to the requests that triggered them.

( PH:0x05, SH:0x10 ) - ZCL APS Ack Command
Overview
The ZCL APS Ack command is sent by the Module to the Host on reception of an equivalent acknowledgement from the network, triggered by the initial transmission of a ZCL message that required an APS Ack among its Response Options. The Module will also generate the command when a given acknowledgment is not received and therefore times out.
Payload

0 | APS Ack Status | 0x00 = APS Ack Received |
1 | Transaction Sequence Number | Transaction Sequence Number that identifies the ZCL message that the Host originally sent out. |

( PH:0x05, SH:0x11 ) - ZCL Response Received Command
Overview
The ZCL Response Received command is sent by the Module to the Host on reception of ZCL message from the network. That is, the command is generated if the Host had configured an outgoing Send ZCL Unicast or Send ZCL Broadcast with Response Options indicating that a response is expected (i.e. enable reception of ZCL Response Received with corresponding Transaction Sequence Number, though the application will also verify the Source Node ID and Command ID).
