Using External bluetooth low energy dongle instead of internal bluetooth

Hello!
Not quite sure if this is the right place to ask for help, but .

I'm creating a project where I have raspberry pi 3b+ inside my house and my main goal is to connect to the raspberry pi outside of my house. Problem is off course that distance is too far to connect, so i was wondering to use external bluetooth dongle. In my test, i used Bluefruit LE Friend (nRF51822).

It seems that i need to connect this ble dongle using serial in / out node. I have already configured internal ble node using node-red-contrib-epi-bluetooth. Is there a possibility to use external bluetooth device and use my predefined bluetooth nodes?
