MetaWear Python SDK
Python SDK for creating MetaWear apps on the Linux platform. This is a thin wrapper around the MetaWear C++ API so you will find the C++ documentation and API reference useful. Also, check out the scripts in the examples folder for full sample code.
This is not the pymetawear package. That is a community developed Python SDK which you can find over here .
pip install metawear
Import the MetaWear class and libmetawear variable from the metawear module and everything from the cbindings module.
from mbientlab.metawear import MetaWear, libmetawear from mbientlab.metawear.cbindings import *
If you do not know the MAC address of your device, use
PyWarble to scan for nearby devices.
from mbientlab.warble import * from mbientlab.metawear import * from threading import Event e = Event() address = None def device_discover_task(result): global address if (result.has_service_uuid(MetaWear.GATT_SERVICE)): # grab the first discovered metawear device address = result.mac e.set() BleScanner.set_handler(device_discover_task) BleScanner.start() e.wait() BleScanner.stop()
Once you have the device's MAC address, create a MetaWear object with the MAC address and connect to the device.
device = MetaWear(address) device.connect()
Upon a successful connection, you can begin calling any of the functions from the C++ SDK, for example, blinking the LED green.
pattern= LedPattern(repeat_count= Const.LED_REPEAT_INDEFINITELY) libmetawear.mbl_mw_led_load_preset_pattern(byref(pattern), LedPreset.BLINK) libmetawear.mbl_mw_led_write_pattern(device.board, byref(pattern), LedColor.GREEN) libmetawear.mbl_mw_led_play(device.board)
