Explainer https://github.com/WICG/serial/blob/main/EXPLAINER_BLUETOOTH.md Specification https://wicg.github.io/serial/#serialport-interface Summary This feature adds a boolean SerialPort.connected attribute. The attribute is true if the serial port is logically connected. For wired serial ports, a port is logically connected if the port is physically attached to the system. For wireless serial ports, a port is logically connected if the device hosting the port has any open connections to the host. Previously, only wired serial ports dispatched connect and disconnect events. With this feature, Bluetooth RFCOMM serial ports will dispatch these events when the port becomes logically connected or disconnected. This feature is intended to allow applications to detect when a Bluetooth RFCOMM serial port is available without opening the port.

Bluetooth RFCOMM support was previously reviewed: https://github.com/w3ctag/design-reviews/issues/854 TAG review status Not applicable Risks Interoperability and Compatibility Web Serial has not yet been adopted by other browser engines which increases interoperability risk. Gecko: Neutral (https://mozilla.github.io/standards-positions/#webserial) Deferring to the Web Serial (Add-On Gated) position. Mozilla has not commented on this specific feature. WebKit: Negative (https://webkit.org/tracking-prevention) Apple is opposed to Web Serial API, we assume they also oppose any extensions to the API. Web developers: Positive This feature was requested by an internal partner. Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Web Serial API is not implemented for Android WebView. Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No Web Serial is not implemented on Android. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? No Flag name on chrome://flags None Finch feature name SerialPortConnected Requires code in //chrome? False Tracking bug https://crbug.com/1488031 Launch bug https://launch.corp.google.com/4297948 Estimated milestones Shipping on desktop 129 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
