## What is BlueHHT?

BlueHHT is a virtual hand held terminal (HHT) for use with GSI's (Gauging Systems Inc.) tank gauging transmitters. It is able to configure and monitor GSI's APTB2, APTB3, and APTB3.6 transmitter cards via a wireless UART device.

BlueHHT is not a general purpose hand held terminal emulator. It only supports the specific GSI devices described here. If you need a general purpose hand held terminal emulator, please refer to the BlueQTerm app.
