thinkgear-py3 2.3

ThinkGear Serial Stream Protocol implementation

Installation

To use ThinkGear, first install it using pip:

(.venv) $ pip install thinkgear-py3
(.venv) $ pip install pybluez2  # For Bluetooth discovery
(.venv) $ pip install pyserial  # For serial communication

Using Serial Communication

For connecting via a serial port, such as COM1 at a speed of 57600 baud, you can use the ThinkGearSerial class. The following examples demonstrate how to read and print PoorSignal, Attention, and Meditation data points.

Example for Windows

from thinkgear.serial import ThinkGearSerial
from thinkgear import PoorSignalDataPoint, MeditationDataPoint, AttentionDataPoint

# Create an instance of ThinkGearSerial
t = ThinkGearSerial()

# Connect to the device (e.g., COM1 at 57600 baud)
t.connect(("COM1", 57600))

# Continuously read and process data
while True:
    for data_point in t.read():
        if isinstance(data_point, PoorSignalDataPoint):
            print("Poor signal:", data_point.value)
        elif isinstance(data_point, AttentionDataPoint):
            print("Attention:", data_point.value)
        elif isinstance(data_point, MeditationDataPoint):
            print("Meditation:", data_point.value)

Example for Linux

from thinkgear.serial import ThinkGearSerial
from thinkgear import PoorSignalDataPoint, MeditationDataPoint, AttentionDataPoint

# Create an instance of ThinkGearSerial
t = ThinkGearSerial()

# Connect to the device (e.g., /dev/ttyUSB0 at 57600 baud)
t.connect(("/dev/ttyUSB0", 57600))

# Continuously read and process data
while True:
    for data_point in t.read():
        if isinstance(data_point, PoorSignalDataPoint):
            print("Poor signal:", data_point.value)
        elif isinstance(data_point, AttentionDataPoint):
            print("Attention:", data_point.value)
        elif isinstance(data_point, MeditationDataPoint):
            print("Meditation:", data_point.value)

Using Bluetooth Communication

For Bluetooth communication, you can discover and connect to a ThinkGear device. The following steps demonstrate how to discover a Bluetooth device and establish a connection.

Device Discovery

You can discover nearby Bluetooth devices with a specific name, such as MyndBand.

from thinkgear.discover import discover

# Discover a device with the name containing "MyndBand"
device_info = discover("MyndBand")
print(device_info)  # Example output: ('XX:XX:XX:XX:XX:XX', 5)

Note: Device discovery is a slow operation. It is good practice to save the discovered device’s address and port for future connections.

Connecting to a Bluetooth Device

Once you have the device’s address and port, you can use ThinkGearBluetooth to connect and process data points.

from thinkgear.bluetooth import ThinkGearBluetooth
from thinkgear import PoorSignalDataPoint, MeditationDataPoint, AttentionDataPoint

# Create an instance of ThinkGearBluetooth
t = ThinkGearBluetooth()

# Use the discovered device information (address and port)
device_info = ('XX:XX:XX:XX:XX:XX', 5)
t.connect(device_info)

# Continuously read and process data
while True:
    for data_point in t.read():
        if isinstance(data_point, PoorSignalDataPoint):
            print("Poor signal:", data_point.value)
        elif isinstance(data_point, AttentionDataPoint):
            print("Attention:", data_point.value)
        elif isinstance(data_point, MeditationDataPoint):
            print("Meditation:", data_point.value)

Notes

• When using serial communication on Windows, ensure that the COM port (e.g., COM1) is correctly configured.

• On Linux, ensure you have the appropriate permissions to access the serial port (e.g., /dev/ttyUSB0). This might involve adding your user to the dialout group or running the program with sudo.

• Bluetooth discovery is time-consuming. Save the device’s address and port once discovered to avoid repeated discovery operations.
