QBluetoothDeviceDiscoveryAgent::MissingPermissionsError when running on arm macos

[KorvinSzanto]

I get the following after building with cmake 3.26.3:

./build/src/cli/dokit status
dokit.cli.command: Looking for first available Pokit device...
qt.bluetooth.darwin: A proper Info.plist with NSBluetoothAlwaysUsageDescription entry is required, cannot start device discovery
pokit.ble.discovery: Pokit device scan error: QBluetoothDeviceDiscoveryAgent::MissingPermissionsError
dokit.cli.command: Bluetooth controller error: QBluetoothDeviceDiscoveryAgent::MissingPermissionsError

Thanks @KorvinSzanto, I'll take a look 😊

So it looks like I'm going to have to convert the macOS app from a single executable, to an app bundle instead. This is mostly done already, but it does mean that that the CLI invocation will look a little different, ie instead of:

./build/src/cli/dokit status

it will become:

./build/src/cli.app/Contents/MacOS/dokit status

It might be possible to make it nicer with a symlink? (I thought for later).

I'll also package the app into a *.dmg file, but that will take a little longer, but you can test before that's done.

Anyway, work in progress... 😄

This was working for me for awhile with #10 applied but it has decided to stop working for some reason. Instead of the behavior originally described I see a panic showing essentially the same failure:

This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSBluetoothAlwaysUsageDescription key with a string value explaining to the user how the app uses this data.

Thanks @KorvinSzanto, I've merged, moved to a CMake variable, and populated the rest of the Info.plist file.

That is really odd. I'll do some digging 🤔

Hey there,

I am struggling with this too.

I tried two ways. With the first one, macOS does not even ask about permissions:

> ./dokit.app/Contents/MacOS/dokit scan
dokit.cli.command: Scanning for Pokit devices...
qt.permissions: Could not find permission plugin for QBluetoothPermission. Please make sure you have included the required usage description in your Info.plist
qt.bluetooth.darwin: Use of Bluetooth LE requires explicitly requested permissions.
pokit.ble.discovery: Pokit device scan error: QBluetoothDeviceDiscoveryAgent::MissingPermissionsError
dokit.cli.command: Bluetooth discovery error: QBluetoothDeviceDiscoveryAgent::MissingPermissionsError

with this, macOS at least asks for BLE permissions but crashes after granting (see below):

> open -n ./dokit.app --args scan

Thanks and regards
