Repository: redback-smartbike-iot

The IoT repository is only split across three directories:

  1. Archive contains old and retired code, research, and documentation.
  2. Drivers contains currently used driver code.
  3. scripts contains bash scripts used to run driver code.

Dependencies​

Several dependencies are used by the drivers:

  • paho-mqtt is used for MQTT functionality
  • gatt library is used for GATT functionality

Drivers/lib/ directory contains our in-house library/common code - including:

  • constants.py for constants used across drivers such as MQTT example topics, upper and lower bounds for valid value ranges, etc.
  • mqtt_client.py which contains our standard mqtt client which should be used by all drivers.
  • ble_helper.py which is used by drivers to match UUIDs of characteristics & services and convert values to their OP codes.
  • gatt/ directory which contains the gatt_linux.py updated gatt library used by some drivers.

Both the in-house and external dependencies help to standardise and streamline code.

scripts​

The scripts directory holds our bash scripts for running driver code.

The start_all.sh script is the primary Smartbike process script which starts all relevant drivers.

ble-auto-connect​

ble-auto-connect/ sub-directory contains the ble_auto_connect script: it is made up of a bash script and expect script. To find out more about the ble_auto_connect script see the documentation.

Drivers​

Drivers drive the functionality of the Smartbike. They connect, control and read values from a specific Smartbike component. Multiple drivers are used to drive the whole Smartbike.

button_control​

button_control.py drives the turning button code and any other buttons.

kickr_climb_and_smart_trainer​

wahoo_device.py drives the KICKR Climb's incline control and KICKR smart trainer's resistance control. It also reads the speed, cadence and power values from the KICKR smart trainer.

incline_and_resistance_control.py is the starter for the wahoo_device.py driver. It takes arguments from the starting script and reads loaded environment variable values.

fan​

fan.py drives the Wahoo Headwind Blueooth Fan, connecting to and controlling the fan's blowing force.

heart_rate_sensor​

heartrate.py drives the TICKR heart rate monitor, connecting to and read & publishing the heart rate data from the TICKR.

Archive​

The Archive directory holds old and retired code. This includes retired drivers (mostly predefined workout "routines" for the Smartbike), code for remotely connecting to and controlling the Raspberry Pi, a very different and old version of the VR game. It also holds old documentation and research.
