Is there a way to disable join on power up?

Here is my operating conditions:

Coordinator in API mode, network started.

Router in API mode, not joined to any network.

If I enable joins on the coordinator, I would like to not have the router join on power up, rather I would like to send an API command to the router to say ‘join now’. I can use the AT DJ command after the router is powered up, but that setting is not saved, and the router joins before I can issue any commands.

Is there a way to do this?

Thanks!

All you can do is control Joining by setting the NJ value on your Coordinator to 0 to disable or any value to FF when you want to Enable joining.
