Using TC55 on-screen keyboard with RFD8500

I am trying to get an RFD8500 to work with a TC55 and have the Android Keyboard available for data entry.

I can attach the RFD8500 and scan tags in but the Android Screen  keyboard is not available

Under settings the RFD8500 shows up as Physical Keyboard. THe only way to get the popup keyboard to display is to end the BT session to the RFD8500
