DeviceInfo.swift

Purpose

DeviceInfo.swift defines a lightweight data structure used to represent individual sensor devices such as smart socks, smart bands, or MetaWear nodes. It includes an enum for device type and a struct that encapsulates identifying details about a device.

Enum: DeviceType

enum DeviceType: String {
    case handLeft = "LH"
    case handRight = "RH"
    case footLeft = "LF"
    case footRight = "RF"
}

Defines a set of known device locations or roles:

  • LH: Left Hand

  • RH: Right Hand

  • LF: Left Foot

  • RF: Right Foot

These identifiers are used to distinguish devices in multi-sensor setups.

Struct: DeviceInfo

struct DeviceInfo {
    var type: DeviceType
    var macAddress: String
    var name: String
    var side: String
}

Fields:

  • type: Enumerated type of the device (from DeviceType).

  • macAddress: Unique hardware identifier for the BLE device.

  • name: Human-readable name (e.g., “Right Sock”).

  • side: Custom side descriptor, e.g., “Left”, “Right” (more flexible than enum).

Usage

Used extensively throughout the iOS codebase, particularly by:

  • DeviceRegistry.swift for registering known devices.

  • Sensor handlers to identify which data belongs to which device.

  • File naming and metadata during data export.
