Run Bluetoothctl on DSGW-210?

I have successfully accessed the router through ssh. Our JAR requires Bluez, which I have installed on the router. However, when I run bluetoothctl, I cannot find the controller. For example, when running “power on” within bluetoothctl, I get the errror “ no default, controller available” Please advise

Gateway is not installed with bluez stack by default, if requried to use the bluetoothctl or bluez stack, please note it in the sample order.
