MetaWearDevice.swift

Purpose

MetaWearDevice.swift defines a foundational wrapper class for MetaWear Bluetooth sensor devices. Though minimal in this version, it sets up the base for managing sensor state and board communication.

Imports

import Foundation
import MetaWear
import MetaWearCpp

  • MetaWear / MetaWearCpp: Libraries used to interact with MetaWear hardware.

  • Foundation: Standard Swift framework for system types and utilities.

Class: MetaWearDevice

class MetaWearDevice {
    var board: OpaquePointer?
    var mac: String?
}

  • board: A pointer to the C-level MetaWear device board structure. Used for invoking native functions from MetaWear C++ SDK.

  • mac: Optional MAC address (e.g., "D7:AA:32:1C:44:89") identifying the device.

This class is typically extended or composed within handlers to initialize, configure, and manage real-time BLE communication with MetaWear wearables.

Future Expansion

In more advanced versions, this class may include:

  • Device configuration (sampling rate, filters)

  • Event handlers (e.g., motion triggers)

  • Start/stop stream commands

  • Battery level or connection status tracking
