( PH:0x02, SH:0x05 ) - Link Key Write CommandOverviewThe Link Key Write command is sent by the Host to the Module in order to set the application Preconfigured Link Key. The Host may only set the Preconfigured Link Key while the application is in the Network Down state. If the Host subsequently forms a network as a coordinator, the key will be applied as the Global Trust Center Link Key. Otherwise, if the Host joins a network as either a router or end device, the key will be applied as the Joining Key. The Preconfigured Link Key is not stored in non-volatile memory and must therefore be set prior to forming or joining a network subsequent to a Reset or power-cycle. If the Host does not manually set the key, the application will use the default Preconfigured Link Key specified by the Zigbee Home Automation Specification. PayloadByte Index | Field Name | Notes |
