How can I use BlueZ and gatttool with Bluefruit modules?

BlueZ has a bit of a learning curve associated with it, but you can find some notes below on one option to send and

receive data using the BLE UART Service built into all of our Bluefruit LE modules and boards.

These commands may change with different versions of BlueZ. Version 5.21 was used below.
