Reach Protocol Web Client

This library is designed to facilitate communication with devices that implement the Reach Protocol, using a user-defined transport method (e.g. BLE). Currently-supported services are:

  • Parameter Repository (discover, read, write, notify)
  • Commands (discover, send)
  • Command-Line Interface (send, receive)
  • Files (discover, download, upload)
  • Time (read, write)
  • WiFi (discover, connect, disconnect)

Usage

Communication with a Reach-enabled device is achieved by creating a new DeviceAccess object, which provides methods for accessing state, reacting to events, and sending commands to the device. When creating a DeviceAccess object, a transport method must be provided that extends the NetworkAccess abstract class with implementations of the constructor and sendBytes method, along with calling the received method when bytes are received.

Changelog

  • 1.4.3
    • Bugfix to handling of headers with reported size over 255 bytes.
  • 1.4.2
    • Removed outdated "read after timestamp" configuration from readParameters.
    • Removed abstract connect method from NetworkAccess due to lack of utility in varied implementation contexts.
    • Removed connect method from DeviceAccess for above-stated reason.
    • Added optional configuration to pingString method for consistency.
    • Improved TSDoc documentation of DeviceAccess and NetworkAccess.
  • 1.4.1
    • Bugfix to WiFi service
    • Bugfix to classic header selection
  • 1.4.0
    • Implemented request state handling for file transfers, including substantial changes to the FileTransfer class.

    • Transitioned to new header format, with use of "classic" headers configurable in DeviceAccess.

    • Exposed access to timeout in read/write file functions
    • Bugfixes to handling of file transfer init response
