LSB Binary Type
A type value of LSB Binary Type indicates that the version string is being provided as a series of binary encoded bytes that represent the version string in a dotted version format with the least significant byte provided first. For example, a binary value of 0x01,0x02,0x03,0x04 provided using this encoding would be translated to 4.3.2.1 (or possibly 4.3.2rc1) when displayed to the user. This is the default encoding for version numbers.
MSB Binary Type
A type value of MSB Binary Type indicates that the version string is being provided as a series of binary encoded bytes that represent the version string in a dotted version format with the most significant byte provided first. For example, a binary value of 0x05,0x06,0x07, 0x08 provided using this encoding would be translated to 5.6.7.8 (or possibly 5.6.7rc8) when displayed to the user.
String Type
A type value of String Type indicates that the version string is being provided as an ASCII encoded string of length n. The value will not be null terminated as the length is provided. For example, a binary value of 0x31,0x2e,0x32,0x2e,0x30,0x72,0x63,0x31 provided using this encoding would be translated to 1.2.0rc1.
Invalid
A type value of Invalid indicates that the requested element is invalid. Typically this indicates that a request was made for an index which lies outside of the valid range of version string indices.

The Restore Defaults frame is sent from the Host to the Module and serves to restore the Module to its factory default settings. The command has no payload.
Effect on Receipt
The Module restores all non-volatile elements to their factory default settings, leaves the network if it is joined to one or dissolves the network if it has formed one, and then reboots.

The Host shall send the Host Startup Ready command to the Module after it starts up and is ready for communication. The command has no payload.
Effect on Receipt
On receiving the command, the Module will respond with the Startup Sync Request command. If the Module is in the Already Running state (see payload for Startup Sync Request ), it signifies that this command was received due to an unexpected reset of the Host. In this case, the Module will have retained all its application cache and attribute values, but will suspend network operations and return to the Startup Synchronization phase.
| Anchor | ||||
|---|---|---|---|---|
|
The Startup Sync Request command is sent by the Module on startup or as a response to the Host Startup Ready command. Upon issuing this command, the Module suspends execution of the full application until the Host has completed all desired configuration and updates against it.
The Module resends this command every five seconds until the Host sends the Startup Sync Complete command in response, signaling the completion of the configuration and update process.
Payload for Startup Sync Request Command
Byte Index | Field Name | Notes |
|---|---|---|
0 | Running State | 0x00 = Starting Up |
1 | Configuration State | 0x00 = Factory Default |
The Running State indicates whether the Module has just powered up or is already running. If the Running State indicates the latter, it signifies that the Host experienced a unilateral reset.
The Configuration State indicates the application configuration state of the Module. The Factory Default state indicates that the Module is operating for the first time post-production, or subsequent to the reception of the Restore to Default command from the Host. The Needs Endpoint Configuration state indicates that the Module has restored all default configurations (Manufacturer ID, etc.), but still requires the Host to configure application endpoints, clusters and attributes. This state will occur after a soft or hard reset of the Module, regardless of the amount of non-volatile memory available.
Expected Host Action
The Host may receive the Startup Sync Request either during a synchronized power up or after a unilateral reset of the Module. The Host shall process both scenarios in the same manner.
If the Running State of the Module is Already Running the Host is not required to configure endpoints, clusters and attributes and perform updates on the values of the latter. Instead, the Host should query attribute values and cached event data from the Module in order to synchronize its internal state with that of the application.
If the Configuration State of the Module is Factory Default, the Host shall perform a full configuration of the application, specifying the IEEE functional device type, security configuration, endpoints, etc. If the Configuration State is Needs Endpoint Configuration, the Host shall configure the application endpoints, clusters and attributes accordingly. If Configuration State is Fully Configured, no further configuration action is required of the Host.

The Host shall send the Startup Sync Complete command to the Module in response to a Startup Sync Request and upon completion of all startup configurations and updates to the latter. The command has no payload.
Effect on Receipt
The Module acknowledges reception of the command with a Status Response indicating Success, after which it runs the full application. If the Module was previously joined to a network it will rejoin that network. Additionally, application configurations are backed up to non-volatile memory for restoration on the next startup.
Please note that Host configurations for endpoints, clusters and attributes are not preserved in non-volatile memory; thus they must be reconfigured after any soft or hard reset of the Module.
Status Response to Startup Sync Complete Command
Status Response | Enum | Description |
|---|---|---|
Success | 0x00 | Module received the command and will start the full application. |

The Attribute Report Passthrough Control message is sent from the Host to the Module. The payload length is 1 octet.

Expected Host Action
The Host must process and respond to Image Block Request messages until the Module sends a Upgrade End Request
The Host must set status to MALFORMED_COMMAND (0x80) and return a 0 length data block if the Image Offset is outside the range of the file length.
