# movesense_exercise

Simple Movesense sensor app

The functionalities:
 * Calculates 1s average of sum vector from 3d acceleration data
 * Offers an API for subscribing to the value
 * Blinks the LED every time it publishes the calculations
 * Stops data collection, publicking and blinking if there are no subscribers

Requires the Movesense SDK.

Follow the instructions at https://bitbucket.org/suunto/movesense-device-lib/src/master/
 1. Install the dependencies: `cmake`, `ninja`, GNU toolchain for ARM embedded and `nrfutil`
 2. `git clone git@bitbucket.org:suunto/movesense-device-lib.git`
 3. `git clone http://matetelki.eu:3000/denes/movesense_exercise.git`
 4. `cd movesense-device-lib`

Compile and generate packages with linux inside the SDK:
 1. `mkdir excerciseBuild`
 2. `cd excerciseBuild`
 3. `cmake -G Ninja -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ -DCMAKE_TOOLCHAIN_FILE=../MovesenseCoreLib/toolchain/gcc-nrf52.cmake ../../movesense_exercise`
  * Add ` -DCMAKE_BUILD_TYPE=Release ` for release builds.
 4. Issue `ninja` to compile
 5. Create OTA firmware update package with `ninja dfupkg`

Run simulations with Windows, inside the SDK:
 1. `mkdir simuBuild`
 2. `cd simuBuild`
 3. `cmake -G "Visual Studio 15 2017" -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ ../../movesense_exercise`
 4  Open the generated `Project.sln` file and build with Visual Studio
 5. Copy `acceleration.cvs` test data to `Debug`
 6. Run the simulation build: `Movesense.exe` with `Debug` being the current working directory.
 7. Subscribe and observe the behaviour from another shell with: `tools/wbcmd (Win).exe --port TCP127.0.0.1:7044 --path /Exercise/Sumvector/Denes --op subscribe`
