Any chance of OTG MAX getting the AP One Controller mechanism that exists in the Peplink Balance?
MAX OTG does not support AP Controller at this moment, you can consider to use MAX 700/HD2 series which supports AP Controller.
What about in the future
There are no plans to add the AP Controller to the Max On-The-Go.
Max OTG is designed for portable usage. Please consider Max700/HD2 if you need AP Controller.
