D2Relay

D2 Relay is a small tool to relay measurements of a Leica DISTO™ D2 device to the console. This tool is Linux only due to its dependency on python-gatt.

Prerequisites

You need to install gatt integration for python. To do so only for your user account it is sufficient to execute:

$ pip install --user gatt

Collaboration

There are many ways to collaborate, please open an issue or a pull request. Some ideas:

• separate python-gatt from the tool itself to support Windows, Mac or any other platform
• create a proper d2relay module to encapsulate the functionality
• support other Leica BLE devices

Todo

Plenty of hints can be found in my notes while reverse engineering my device.

• Infer correct units
• Detect error states such as 255 (too close)
• Make things configurable by using command line parameters
• Interactive Mode: trigger measurements over BT
• Demonstrator with FreeCAD or the like
