( PH:0x02, SH:0x08 0x0B ) - Network Key Security Profile Write CommandOverviewThe Network Key Write command is sent by the Host to the Module in order to set the application Preconfigured Network Key. The Host may only set the Network Key while the application is in the Network Down state, after which the key will be automatically randomized. The Network Key is only applied if the Host subsequently forms a network as a coordinator. If serving as a router or end device, the application will receive a Network Key from the network Trust Center. The Network Key is not stored in non-volatile memory and must therefore be set prior to forming a network subsequent to a Reset or power-cycle. If the Host does not manually set the key, the application will generate a random value for it upon forming a

| This command can be used to disable the security mechanism that is required for Zigbee 3.0 compliance, specifically for encryption of application-level messages. MMB does not endorse, and accepts no responsibility for, device implementations that opt to use this lower level of security. |
OverviewNote: This feature is available in RapidConnect 3.4.x and above. The Network Security Profile Write command is sent by the Host to the Module to set the security level of the network. The security level must be set before forming or joining the network.
