1、Problem Description:

1）When the Assoc/Device list is full, how should we manually delete the devices in the Assoc/Device list (AssociatedDevList)?

If the coordinator's "NWK_MAX_DEVICE_LIST" is set to 10, the coordinator can add 10 devices. When one of the devices is restored to factory settings, the coordinator does not know. Does the coordinator keep the information for this device in the Assoc/Device list until the end of the device's life? At this point I want to manually delete the information of this device in the Assoc/Device list, how to delete?

Yes, coordinator will keep the device in the Assoc/Device list until it is aged out. You can try to use API AssocRemove to remove it manually if you want to do this.

Hi, YiKai.
Thank you for your reply.
I think this can happen if you delete the device information using the "AssocRemove" function:
The coordinator manually deletes the information of a power-off device in the Assoc/Device list and the TCLK list. When the device is powered on, the device rejoins the original network through rejoin. At this point, the coordinator will re-add the information of this device to the Assoc/Device list, but the information of this device in the TCLK list will be lost forever. How will this affect the device?

I remember this API won’t delete TCLK list.

Yes, But I think the coordinator needs to keep the TCLK list and Assoc/Device list synchronized, so I will delete the Assoc/Device list information and delete the TCLK list information.

It depends on your intention so I would suggest you to do both from your applicaiton if you mean to remove both.
