James Rich a6f8f456fd fix(serial): treat USB unplug and open failure as transient
Serial transports defaulted to isPermanent=true for any disconnect path,
including USB unplug and port-open failure. Both conditions can resolve
without explicit user re-selection: replug, OS re-enumeration, permission
grant. Only an explicit close() (user disconnects) is a true permanent
disconnect.

- StreamTransport: flip onDeviceDisconnect default isPermanent to false;
  close() now passes isPermanent=true explicitly.
- SerialRadioTransport (Android): pass isPermanent=false explicitly on
  USB unplug callback path.
- SerialTransport (JVM): flip both the open-failure path and the read-
  loop teardown to isPermanent=false; both are recoverable conditions.

:core:network

Overview

The :core:network module handles all internet-based communication, including fetching firmware metadata, device hardware definitions, and map tiles (in the fdroid flavor). It also provides the shared radio transport layer (TCPInterface, SerialTransport, BleRadioInterface).

Key Components

1. Ktor Client

The module uses Ktor as its primary HTTP client for high-performance, asynchronous networking.

2. Remote Data Sources

  • FirmwareReleaseRemoteDataSource: Fetches the latest firmware versions from GitHub or Meshtastic's metadata servers.
  • DeviceHardwareRemoteDataSource: Fetches definitions for supported Meshtastic hardware devices.

3. Shared Transports

  • BleRadioInterface: Multiplatform BLE transport powered by Kable.
  • TCPInterface: Multiplatform TCP transport.
  • SerialTransport: JVM-shared USB/Serial transport powered by jSerialComm.
  • BaseRadioTransportFactory: Common factory for instantiating the KMP transports.
