@MYSTRAVIL MYSTRAVIL released this 10 Aug 06:37

Everything from 0.2.3, plus a second round of tray UX and a smarter Connect Now.

New in this build

  • Connect Now actually connects. It now actively reaches out and pulls a paired, in-range phone up
    from the PC (the same thing Windows' own Bluetooth "Connect" does), instead of only working when the
    phone was already connected. If the phone is genuinely unreachable it backs off rather than hanging.
  • Left-click opens the tray menu (previously right-click only).
  • Event sounds — a soft low chime on connect / disconnect / and when one half drops (degraded),
    with a Sounds toggle in the menu to silence them.
  • Auto-pick phone — the Phone submenu is now a checkable list: tick the phones you use, and the app
    auto-connects whichever is present (first one present wins; a working connection is never dropped to
    switch). Your previous single selection is migrated automatically.
  • Copy Diagnostics now spans midnight (it reads recent log lines across the day boundary, not just
    today's file).

Known limitations (unchanged)

  • Windows 10 (19041+) only. Not Windows 11 — call registration is blocked there for sideloaded apps.
  • Outgoing call audio can be narrowband depending on your Bluetooth stack (driver, not the app).
  • No in-app call-output picker; call audio follows the Windows default communications device.
  • The in-call keypad (DTMF) does not work — that window is Windows' own call UI.
  • If a phone won't connect even from Windows' own Connect button, the pairing is stale — re-pair on both
    sides.

Prerelease (0.x). Requires the one-time certificate-trust step below.

Install

Klangbruecke is a sideloaded MSIX signed with a self-signed certificate, so Windows will not install
it until that certificate is trusted. There is no "install anyway" prompt for MSIX - this step is
required, and it is a one-time thing per machine.

1. Trust the certificate (one time, from an elevated PowerShell):

Import-Certificate -FilePath .\Klangbruecke.cer -CertStoreLocation Cert:\LocalMachine\TrustedPeople

2. Install (or upgrade) the app - from Windows PowerShell, not PowerShell 7 (the Appx module
does not load in pwsh):

Add-AppxPackage -Path .\Klangbruecke-0.2.4.msix

Klangbruecke then starts automatically and lives in the system tray. Windows 10 build 19041 or later
is required. See the README for what it does and
how to test music and calls.
