Summary

Support Bluetooth RFCOMM services in the Web Serial API. The Bluetooth RFCOMM (Radio frequency communication) protocol provides emulated RS-232 serial ports. This feature would enable applications to make connections to RFCOMM services on paired Bluetooth Classic devices using the Web Serial API.

Motivation

1. Allow access to serial ports on Chrome platforms that do not map Bluetooth serial port services to serial device nodes (i.e. COM or /dev/*). 2. Allow access to Bluetooth RFCOMM services with custom (non-standard) UUIDs.
