СС2480 Security mode



Hi.

I have a network with a coordinator and some end devices. I want to transmit encrypted data from the end devices to the coordinator. Some of the end devices to encipher data, the other - not. Then coordinator receives this data with AF_INCOMING_MSG, which has SecurityUse field, but this field is 0 at all times, and I cannot recognize data encrypted by the end device.

How can I found out that the data encrypted by an end point or not?

When I turn on security I transmin new key - ZcdNvPreCfgKey, ZcdNvPreCfgKeysEnable = 0 and ZcdNvSecurityMode = 1.

Thank you.
