Example application code for running a SensiML Knowledge Pack recognition app for the Bosch Nicla Sense ME board.
In order to run a Knowledge Pack, you must first have a model generated via SensiML Analytics Studio.
When downloading a model, you will need to select Bosch Nicla Sense ME from the target device.
Unzip the download to a location of your choosing. In the folder, you will find the following directories:
- knowledgepack/
- knowledgepack_project/
- libsensiml/
Copy the files from libsensiml to lib/sensiml. It is ok to overwrite these, but do not commit them in a pull request. The files provided in this repository are for examples only.
Copy the files from knowledgepack_project to src/
This should be sml_recognition_run.cpp, which will contain the necessary model running code to enable recognition on the device.
Build/upload the firmware.
If you wish to run the IMU at a different frequency (default for data capture and this example is 200 Hz), modify the ODR_IMU in include/sensor_stream.h
As the Data Capture Lab of the SensiML Toolkit does not actively configure the device, a capture configuration isn't generated when creating the model code.
For Serial output, simply connect to your Bosch Nicla Sense ME via any serial monitoring application. You should see an output similar to this:
{"ModelNumber":0,"Classification":3,"SegmentStart":268400,"SegmentLength":200,"FeatureVectorLength":6, "FeatureVector":[87,62,50,0,124,179]}
