USB BLE Dongle

The application has been developed using BLE drivers to operate USB dongles based on nRF52840 SoC, such as the https://es.farnell.com/nordic-semiconductor/nrf52840-dongle/m-dulo-bluetooth-v5-2mbps/dp/2902521

Similar dongles with plastic encapsulation can be acquired from Minew, which can be found on Aliexpress: https://es.aliexpress.com/i/1005001908490775.html

The dongles needs to be flashed with a connectivity firmare, that can be made automatically with the nordic application nRF Connect for Desktop Bluetooth Low Energy Standalone (https://github.com/NordicPlayground/pc-nrfconnect-ble-standalone) upon dongle connection.

Installation

Enter the directory where the source code is downloaded and create a python virtual environment with the required dependencies, which are set in pyproject.toml, with:

poetry install

Once installed the required dependencies, the application must be launched from within the poetry environment just created with:

python main.py cli # for launching the main interface
python main.py capture --duration 60 # for launching an unattended quick capture of 60 seconds

When using the application after the initial installation, only activation of the poetry virtual environment is required, which is done with:

poetry shell

or just:

poetry run python main.py cli

Usage

Once we launch application with the cli command:

$ poetry run python main.py cli

the following interface will be shown:

The application first initializes the usb dongles used to connect with the sensors, and presents available adapters and the main menu interface.

If the logger_config_collect_sensors_on_startup variable on the .env is set to True, the application will perform an initial sensor recruitment and connect those sensors in range. The Collect available sensors in the main menu launch this same operation.

Sessions

The application uses the concept of LoggerSession to handle data captured from sensors. Sessions comprises a session_name and a session_type, thus captures can be organized, while main session identification includes the session creation timestamp.

• Quick capture session launch a quick capture process with the sensors already connected under a new session with no user intervention. The duration of the capture process is set with the logger_config_default_session_duration variable on the .env file.
• Create session ask for the new session_name and session_type, and navigates to the session menu.
• Select session shows the existing saved sessions to select from and navigates to the session menu.
• List sessions shows information about the saved sessions.
• Delete sessions allows deleting existing sessions.
• Merge sessions allows selecting several existing sessions and merge them into a single session. This is useful in case of capture process launched in parallel on different os processes.
• Restore session allows selecting sensor capture data cache files and building a capture session from them. This is useful in case of long-running capture processes that may force application gets killed by the os prior gathering sensor data files.
• Clear sessions data allows deleting existing sessions data, without deleting sessions itself.

Session

Creating a new session or selecting an existing one leads to the Session menu:

A summary of the session selected and the currently connected sensors is presented, and session menu options are displayed:

• Show session data displays a summary of the session and information about the data captured and analyzed (if so), plus allows generating a plot of the data, that will open a page in a browser (depending on the amount of data, it may take a while). Note that browser cannot be opened if the gateway is operated over an ssh connection.
• Start capture launches a capture process, allowing indicating the sensors to use and the duration of the capture process.
• Analyze session data performs an FFT analysis of the captured data by each sensor. This is accomplished also after a capture process if the logger_config_analyze_data_on_capture variable on the .env file is set to True.
• Export session data allows saving session data on a custom location, including the generation of the html reports.
• Delete current session eliminates current session and navigates back to the sessions' menu.
• Edit session allows modifying session_name and session_type, plus entering additional session_notes.
• Clear current session data deletes session data, without deleting the session itself.

Sensors

Main menu option Sensors navigates to the Sensors menu, where we can manage the sensors used by the application.

First, a list with the currently known sensors and its configuration is presented, and then a menu with the available operations is shown:

• Collect available sensors will perform a BLE search for the sensors in range, and will connect them automatically.
• Show sensors will print the list of sensors, and will ask for connecting them.
• Edit sensors allows defining sensor alias and predefined location (preset locations can be established on the .env file).
• Config sensors allows configuring sensor behaviour (axis configuration, sample rate and scale).
• Search sensors launch a BLE scan and allows connecting found sensors (similar to collect available sensors, but does not connect automatically).
• Connect sensors allows connect already known sensors.
• Disconnect sensors disconnect already connected sensors.
• Test sensors enables sensor capture and display packets received on real time, without storing data.

When connecting previously known sensors, sensor configuration is set through BLE. A sensor configuration can be overridden by the default configuration on the .env file if the logger_config_sensor_use_default_configuration variable is set to True.

The application manages the connection procedure to distribute connections among available adapters. Best performance is achieved when each sensor is connected with a different adapter. In case several sensors are connected to the same adapter, that will affect the capture process, leading to missing packets if higher sample rate is selected (thus, 4 adapters are required to maximize throughput). Maximum achievable rate for a sensor connected to a single adapter is 6.k kHz with two axis or 3.2 kHz with three axis, while selecting 6.4 kHz and three axis leads to missing ~10-15% of the packets.

Unattended capture

It's possible to launch an unattended capture from the command line with:

python main.py capture --duration 15 --export-path export

where --duration states the capture duration in seconds and --export-path indicates a directory where captured data will be saved (in addition to the default application data location). If the --duration option is not provided, the default duration configured on the .env file with the logger_config_default_session_duration variable will be used. If the --export-path option is not provided, data will be stored only on the default application data location.

The command will search and connect all the available sensors (considering the constraints imposed on the .env file), generates a new session and launches a data capture of the intended duration. Sensor configuration, as well as alias and location will be retrieved from the last saved data (although configuration can be overriden with the logger_config_sensor_use_default_configuration variable), and data will be stored on the default location and the provided export path.

Environment configuration

The application behaviour can be tuned by using environment variables. The application can handle environment variables defined in a .env file with the following content (purpose of each variable is described inplace):

# Logger configuration
# ====================
# Path to store the logger data
logger_config_data_path=data

# Wether to use partitioning when saving parquet data (split files among sensors' address)
logger_config_use_parquet_partition=False

# Wether to save raw sensor data
logger_config_save_raw_acc=False

# Main menu interface language (ES, EN). Note that remainder application messages will be presented in EN 
# regardless this configuration
logger_config_language=EN

# Wether to show sensors' menu at first level
logger_config_sensor_menu_up=False

# List of expected sensor locations to select when edit sensors
logger_config_known_locations=["POSITION_UP", "POSITION_DOWN", "POSITION_LEFT", "POSITION_RIGHT", "POSITION_EXTRA"]

# Sensors connection configuration
# ================================
# Max number of adapters to use by the application. Set to 0 to use all the available adapters.
# Setting max adapters to 1 uses only one adapter, useful when using the unattended capture mode and
# launching several process in paralel
logger_config_max_adapters=4

# Max number of sensors connected by adapter. Set to 0 to allow connecting all the sensors with the same adapter
# (note that BLE adapter impose additional restrictions on the number of simultaneous connections)
# Setting max sensors to 1 limits one sensor for adapter, useful when using the unattended capture mode and
# launching several process in paralel
logger_config_max_sensors_per_adapter=2

# Max number of sensors connected. Set to 0 to allow connecting all the sensors in range
# Setting max sensors to 1 limits one sensor for application, useful when using the unattended capture mode 
# and launching several process in paralel
logger_config_max_sensors_connected=0

# Wether to search and connect sensors on startup on the CLI mode (does not affect the capture mode).
logger_config_collect_sensors_on_startup=False

# Session capture configuration
# =============================
# Period in seconds for saving sensor data while receiving packets
logger_config_background_save_period=10

# Whether to keep sensor capture cache files prior merging session data (useful in case application 
# may be killed by low memory...)
logger_config_keep_sensor_cache_files=True

# Default session name / session type for unattended capture sessions
logger_config_default_session_name=New session
logger_config_default_session_type=Test

# Default session duration for unattended capture sessions
logger_config_default_session_duration=10

# Performs a raw data FFT analysis upon data capture
logger_config_analyze_data_on_capture=False

# Sensors capture configuration
# =============================
# Wether to use sensors configuration set or force default sensor configuration
logger_config_sensor_use_default_configuration=False

# Default sensor capture configuration
# Sample rate:
#    SAMPLE_RATE_1HZ_LP = 0x08
#    SAMPLE_RATE_12HZ5_LP = 0x09

#    SAMPLE_RATE_6400HZ_HF = 0x17
logger_config_default_sensor_sample_rate=SAMPLE_RATE_3200HZ_HF

# Scale:
#    SCALE_2G = 0x00
#    SCALE_16G = 0x01
#    SCALE_4G = 0x02
#    SCALE_8G = 0x03

#    AXIS_ONLY_X = 0x12
#    AXIS_ONLY_Y = 0x13
#    AXIS_ONLY_Z = 0x11
logger_config_default_sensor_axis=AXIS_ONLY_YZ


# Session data configuration
# ==========================
# Max duration in seconds for plotting raw data (graphic generation is slow and produce heavy files when too much data)
logger_config_plot_max_seconds=60

# Min number of consecutive stream samples to compute FFT
logger_config_analyze_min_stream_samples=4096 # 2^12

# Max number of consecutive stream samples to compute FFT
logger_config_analyze_max_stream_samples=16384 # 2^14
