The device driver library is written in Python, based on the Bleak library. It was verified to work well on an OpenPlotter installation on a Raspberry Pi, as well as a macOS workstation.
- Run device discovery
- Acquire device status and readings (one shot)
- Acquire device readings continuously (subscribe/notify)
- Set device data rate
- Telemetry with NMEA-0183 and SignalK over UDP
pip install --upgrade calypso-anemometerTo install the latest development version from the repository, invoke:
pip install --upgrade git+https://github.com/maritime-labs/calypso-anemometerWe have some documentation about investigating and configuring your Bluetooth/BLE stack and about simulating the telemetry messaging. On this matter, you might want to run through a sequence of preflight checks before going into production.
Discover the ULTRASONIC BLE device and run a conversation on it. By default, the Bluetooth adapter hci0 will be used.
# Get device information with discovery.
calypso-anemometer info
# Get device reading.
calypso-anemometer read
# Get device reading, with compass (roll, pitch, heading).
calypso-anemometer read --compass=on
# Get device readings, continuously at 4 Hz (default).
calypso-anemometer read --subscribe
# Get device readings, continuously at 1 Hz.
calypso-anemometer read --subscribe --rate=hz_1
# Generate fake device readings, continuously at 8 Hz.
pip install --upgrade calypso-anemometer[fake]
calypso-anemometer fake --subscribe --rate=hz_8If you already discovered your device, know its address, and want to connect directly without automatic device discovery, see skip discovery.
Likewise, when your system has multiple Bluetooth adapters, you may want to choose a specific one, see select Bluetooth adapter.
# Get device information w/o discovery.
calypso-anemometer info --ble-address=F8:C7:2C:EC:13:D0
# Get device information w/o discovery, using a specific Bluetooth adapter.
calypso-anemometer info --ble-adapter=hci1 --ble-address=F8:C7:2C:EC:13:D0In order to use the library API, please consult the programs in the examples folder.
Synopsis:
from calypso_anemometer.core import CalypsoDeviceApi
async with CalypsoDeviceApi() as calypso:
reading = await calypso.get_reading()
reading.print()The program can optionally submit telemetry messages in different formats.
Continuously receive device readings and submit them in SignalK Delta Format via UDP:
calypso-anemometer read --subscribe --rate=hz_1 --target=udp+signalk+delta://openplotter.local:4123To make a SignalK server receive the data, create an "UDP receiver" data connection on the Server » Data Connections dialog of your OpenPlotter instance.
Continuously receive device readings and submit them in NMEA-0183 format via UDP broadcast:
calypso-anemometer read --subscribe --rate=hz_1 --target=udp+broadcast+nmea0183://255.255.255.255:10110Note
If you don't have any networking configured on your machine, just use localhost as target address.
To make OpenCPN receive the data, create a corresponding data connection like outlined in those screenshots.
An example NMEA-0183 payload, including multiple sentences, is:
$MLHDT,235.0,T*27
$MLVWR,154.0,L,11.06,N,5.69,M,20.48,K*64
$MLXDR,A,-60.0,D,PTCH#CAL,A,30.0,D,ROLL#CAL*75
$MLXDR,C,33.0,C,AIRTEMP#CAL*6A
$MLXDR,L,0.9,R,BATT#CAL*18- AocpnUltrasonicLink is an Android app for linking Calypso Ultrasonic wind data to OpenCPN, written in Java.
- BLE_Wind is an Arduino firmware for reading data from a Calypso anemometer, written in C++.
- CalypsoUltrasonicAPI is a library for the Calypso Ultrasonic Anemometer, written in Visual Basic .NET and Java, (also) for Android.
- signalk-calypso-ultrasonic is a Signal K server plugin for the Calypso Ultrasonic wireless anemometer, written in JavaScript.
- ultrasonic-ble-react is a React native test app for the Calypso UltraSonic wind sensor, written in JavaScript.
For helping you to find solutions for known problems, we are maintaining a dedicated page at troubleshooting. The topic range is from permission errors to BLE timeouts.
- Kudos to Henrik Blidh, David Lechner, and contributors for conceiving and maintaining the excellent Bleak library.
- Special thanks to Fabian Tollenaar for creating signalk-calypso-ultrasonic.
