From time to time, OmniPreSense provides code updates with new features and/or fixes for its radar

sensors. The embedded code in the OPS241 short range radar sensor can be easily updated to take

advantage of these enhancements. This application note describes how to update the code on the

OPS241 radar sensors.

Update Tools
