Define Bluetooth permissions for a standard Console App in WinRT/C++ - windows

Question

I'm working on a WinRT/C++ application that uses Windows APIs to access to RFCOMM Bluetooth and looks for nearby devices. Then I try to create a service in order to create a connection, so I run:
RfcommDeviceService service = RfcommDeviceService::FromIdAsync(currId).get();
However, the FromIdAsync method returns NULL since, according to the documentation:
If a store app has not declared the right capabilities or the user does not grant consent, the method returns a null object.
The solutions I found online all require to add a <Capabilities> tag to the Package.appxmanifest file. However, I do not have such file, since I'm working on a standard Console app.
Is there another way to grant permissions to my app? Alternatively, can I include manually a Package.appxmanifest file so that I can access the Bluetooth? Or I am completely missing the point here and the error is caused by something else?
EDIT: Minimal reproducible example:
// Store all the devices
vector<DeviceInformation> devices;
// Replace targetAddress with Bluetooth address to pair
string targetAddress = "XX:XX:XX:XX:XX:XX";
// AQS string for RFCOMM devices
hstring selectorString = to_hstring("System.Devices.DevObjectType:=5 AND System.Devices.Aep.ProtocolId:=\"{E0CBF06C-CD8B-4647-BB8A-263B43F0F974}\" AND((System.Devices.Aep.IsPaired: = System.StructuredQueryType.Boolean#True OR System.Devices.Aep.IsPaired: = System.StructuredQueryType.Boolean#False) OR System.Devices.Aep.Bluetooth.IssueInquiry: = System.StructuredQueryType.Boolean#False)");
// Create watcher
DeviceWatcher deviceWatcher = DeviceInformation::CreateWatcher(selectorString);
// Callback function for event handling
auto OnAddedDevice = [](DeviceWatcher watcher, DeviceInformation deviceInfo)
{
devices.push_back(deviceInfo);
};
// New Bluetooth device detected -> callback
deviceWatcher.Added(OnAddedDevice);
// Start watcher
deviceWatcher.Start();
std::cout << "Performing device scan...\n" << endl;
Sleep(4000);
// Stop scanning
deviceWatcher.Stop();
// Print results
for (int i = 0; i < devices.size(); i++) {
string name = to_string(devices[i].Name());
string address = getAddress(devices[i]);
std::cout << "(" << address << ")" << "\t" << name << endl;
}
std::cout << endl;
// Look for target device among the scanned ones
for (int i = 0; i < devices.size(); i++) {
string address = getAddress(devices[i]);
// Match found
if (address == targetAddress) {
// Get ID
auto currId = devices[i].Id();
// Create Service [HERE, FROM IDASYNC RETURNS NULL]
RfcommDeviceService service = RfcommDeviceService::FromIdAsync(currId).get();
// Try to get information about the created service [LAUCHES EXCEPTION SINCE service IS NULL]
auto protectionLevel = service.ProtectionLevel();
}
}
Helper function getAddress is used to parse the device ID
string getAddress(DeviceInformation device) {
string id = to_string(device.Id());
string address = "";
for (int i = 37; i < id.length(); i++) {
address += toupper(id[i]);
}
return address;
}
