Can a plugin filter the list of available ports? For instance serial over Bluetooth creates two virtual ports for initiating and accepting connections (on windows at least). My bespoke monitor filters these and only shows the outbound ports to the user. It also pulls in the Bluetooth device name from WinRT, etc.
Internally the comport IO driver is just a plugin that gets compiled into the main exe (any plugin can be made into a built in, just add the source to the .pro file, add a call to the register function and now the extern plugin is built in).
So you could copy the existing comport IO driver, change the 'REGISTER_PLUGIN_FUNCTION_PRIV_NAME' and 'COMPORT_URI_PREFIX' defines to something else (so it doesn't conflict with the built in 'COM' one). Change the code so filter any comport that isn't for the Bluetooth device. Compile the source and package the resulting .dll using the ExternPluginMaker tool. Done
When the new plugin is installed the new connection dialog you will list your detected "devices" listed along with all the other types (you could prefix them with bluetooth for example).
Feel free to email me if you would like more details.
I didnt see anything on the github or in the source download.
Alternatively an AppImage or Flatpak is a nice way to test software.
After you have them installed and working all you have to do is load the .pro file from the Project directory (https://github.com/TheBeef/WhippyTerm/tree/main/Project) you should be able to just hit the green debug/go button and it should work (you do need to be using the gcc toolchain). This is the same for the Windows build.
Hope this helps.
