Collect geolocated radio decodings from a reelyActive Owl-in-One based on the Tessel 2 platform. Geolocates using a USB GPS and writes radio decodings (raddecs) from a reel module (BLE) and/or from tcpdump (WiFi) to a USB drive.
For complementary functionality, consider instead:
- tessel-edge for real-time packet forwarding
- tessel-monitor to monitor Bluetooth Low Energy advertising traffic dynamics
Consult the following tutorials as step-by-step configuration guides:
Clone this repository, browse to its root, then run:
npm install
All configuration parameters can be found in the file config.js. Update only this file, as required.
| Parameter | Description |
|---|---|
| LISTEN_TO_REEL | Enable listener on reel module (default: true) |
| LISTEN_TO_TCPDUMP | Enable listener on tcpdump (default: false) |
| ENABLE_MIXING | Combine multiple decodings of an individual transmitter into a single raddec (default: true) |
| MIXING_DELAY_MILLISECONDS | Mixing delay of radio decodings (default: 1000) |
| RADDEC_FILTER_PARAMETERS | (see raddec-filter) |
| LOGFILE_NAME_PREFIX | (default: 'roamlog') |
| LOGFILE_EXTENSION | (default: '.csv') |
| LOGFILE_DELIMITER | (default: ',') |
| LOGFILE_MINUTES_TO_ROTATION | (default: 60) |
| STORAGE_MOUNT_POINT | (default: '/mnt/sda1') |
| GPS_MOUNT_POINT | (default: '/dev/ttyUSB0') |
| IS_DEBUG_MODE | Set true and t2 run index.js for console log |
Programming the Tessel 2 requires the t2-cli package which can be installed by following these instructions.
With the Tessel 2 connected to the programming station via USB, from the root of this repository run:
t2 push index.js
The code will be pushed to flash memory on the Tessel and will run every time it boots.
By default, tessel-roam will write to logfiles roamlog-ble-YYMMDD-HHMMSS.csv and roamlog-wifi-YYMMDD-HHMMSS.csv, which it will rotate every 60 minutes, the following comma-separated values:
GPS Epoch,CPU Epoch,transmitterId,transmitterIdType,rssi,lat,lon,speed,course
The tessel-roam software expects the following:
- a reel or reelceiver module connected via UART on Port A
- maximum baud rate of Port A set to at least 230400
- tcpdump installed (only if LISTEN_TO_TCPDUMP is true)
- coreutils-stty installed
- GPS module connected via USB
- thumb drive connected via USB
