Utilities and Python package for the Bosch GTC 400C (and more Bosch tools).

Project description


A Python package to support my random collection of Bosch devices. Most of this code was created by investigating the device communication and their exported files.


This package can be installed or upgraded from the Python Package Index with the help of the pip command:

pip install --upgrade bsch[plotting]

For any plotting, the package relies on matplotlib/numpy. Those packages are only installed if the "extra" plotting is specified in square brackets after the package name.

Bosch GTC 400 C

IR / Thermography Camera

Implemented features:

  • Open the JPEG files saved by the IR camera and extract the embedded binary thermography data, I call this data 'thermoblob'.
  • Extract metadata and the temperature matrix from the thermoblob.
  • Export a thermography plot (tool: gtc400c-thermogram).
  • Interactive plot of the thermography data (tool: gtc400c-plot).
  • Create a custom blend of thermography data on top of the real photo (tool: gtc400c-blend).
  • Download images via FTP when connected to the device via WiFi (tool: gtc400c-ftp).

Planned Support

I own the laser distance measurement tool Bosch GLM 50-27 CG. It has a BLE (Bluetooth Low Energy) interface and I successfully reverse engineered the protocol. Needs some polishing though.
