Auto Enumeration Problems

I keep getting this error when trying to use the xbee auto enumeration.

WARNING:autoenum0:XBeeAutoEnum: __add_new_device. UNABLE to get DD from [00:13:a2:00:40:ac:13:46]

What are some reasons I would note be able to get Device Type Identifier and why should this throw a warning and cause autoenumeration to fail.

The module could be in a sleep state, not associated or within the network.

Can cause issues as the DD value tells the system what kind of node is it and how to interact with it.

Why can’t it get the DD value?
What does this mean for the system?
How do I fix this problem?
Why does this prevent the device from functioning?

The DD value is set on the module and in the Code. You need to be able to query the radio to get a DD value.

If the Gateway and related python code does not know what the device is, it does not now how to access it.

Why does this stop autoenumeration?

Are you able to Query module [00:13:a2:00:40:ac:13:46] DD value using a different module that is in API mode? If so, what is the DD value? Next, what is the API string you are providing to get the DD value in your code?
