Question re: MdocReader

[warren-gallagher]

Are the MdocReader and related Ble and BleConnection classes intended to support the creation of an mdL Verifier on iOS?

I have attempted to get this working by scanning a QR code presented by the EUDI wallet. Here is an example of what the EUDI wallet QR code provides:

mdoc:owBjMS4wAYIB2BhYS6QgAQECIVgg86qzNIr2qiktlGI2oGyEykvPWsIzZAgjQkKthPBlp88iWCB2YHkb-xvYQOwW6sqi5mRFBQ6OXnp6-nZTNsmZPvYhuwKBgwIBowD1AfQKUAAAY3EAABAAgAAAgF-bNPs

When I run my App (SwiftUI code shown below) an error:
Generic(value: "the device did not transmit a central client uuid")

The EUDI wallet always goes into peripheral mode and thus it will not provide a central client uuid. It would appear that the mobile-sdk-swift implementation assumes that it will be the peripheral.

Am I understanding things correctly? Is there a plan to support Central mode for the MdocReader?

import SwiftUI
import MobileSdkFramework

class MyBleReaderSessionStateDelegate : BLEReaderSessionStateDelegate {
    func update(state: BLEReaderSessionState) {
        print("bleSessionStateDelegate: \(state)")
    }
}
struct ContentView: View {
    
    @State var path: [String] = []
    
    var body: some View {
        NavigationStack(path: $path) {
            ZStack {
                VStack {
                    Button("Scan QR Code") {
                        path.append("Scan QR Code")
                    }
                 }
             }
            .navigationDestination(for: String.self) { value in
                QRCodeScanner(
                    onRead: { qrCode in
                        print("QR Code: \(qrCode)\n")
                        path.removeAll()
                        let requestedItems: [String: [String: Bool]] = ["org.iso.18013.5.1": ["given_name": true]]
                        MDocReader(callback: MyBleReaderSessionStateDelegate(), uri: qrCode,requestedItems: requestedItems, trustAnchorRegistry: nil);
                    },
                    onCancel: {
                        print("QR Code Scan cancelled\n")
                        path.removeAll()
                    }
                )
                .navigationBarBackButtonHidden()

            }
            .navigationTitle("mDoc Reader")
        }
    }
}

My App's Info.plist file has:

	<key>NSBluetoothAlwaysUsageDescription</key>
	<string>Secure transmission of mobile DL data</string>

I never see a prompt asking for permission for BlueTooth.
The app's settings does not show a switch for BlueTooth.
I expect that the app never prompts for permission because it fails parsing the URI from the qrCode and never actually attempts bluetooth communications.

You are correct. We have an internal tracking issue for this but it hasn't been prioritised yet.
