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 bluetooth-equipped APTB2, APTB3, and APTB3.5 transmitter cards.

The GSI APTB3.5 (and up) transmitter cards are equipped with an on-board Bluetooth Low Energy (BLE) device and can communicate directly with the BlueHHT app.

The GSI APTB2 and APTB3 transmitter cards require the use of a GSI 1590 Blue Comm module to provide the Bluetooth to Serial conversion necessary for using the BlueHHT app with those devices.

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.
