Unable to connect device using Wi-Fi Direct in Huawei Android 9 (EMUI 9)

Question

I am creating an app to communicate with printer using Wi-Fi Direct.

The app will list all the printers in Wi-Fi direct range once click on displayed printer it will send invitation to printer to connect. Click on accept it will connect.

The app works fine in all the brands (Pixel, Samsung, Asus, Moto etc.) except HUAWEI (Device: P20 lite & MediaPad M5) brand Android 9.

Issue: Click on displayed printer to send connection request. The connection request success but after 7 seconds it get called WIFI_P2P_CONNECTION_CHANGED_ACTION there it says it is not connected. The invitation not received from printer.

Connection Logic:

config.groupOwnerIntent = 0;
config.deviceAddress = deviceAddress;
config.wps.setup = WpsInfo.PBC;
manager.connect(channel, config, new WifiP2pManager.ActionListener() {
    @Override
    public void onSuccess() {
        Log.d(TAG, "Connection request success");
    }
    @Override
    public void onFailure(int reason) {
        Log.w(TAG, "Connection request failed reason : " + reason);
    }
});

Logs:

Are the working devices Huawei's devices? If yes, the app should work in P20 Lite and MediaPad M5. I can help to investigate the issue if you can share the app with me. I have a MediaPad M5 Lite and like to verify the app on the device. — Zinna, Jan 25 '22 at 02:24
@Zinna Thank you very much, We did not tested with other Huawei's devices, We tested Pixel, Samsung, Asus, Moto etc., it works fine. I will share you our POC app (Google Wi-Fi Direct Sample) the same logic we used in our application.

Because I don't have a printer with WiFi Direct, I verified the WiFi Direct POC apk on some Huawei devices including Mate 20 Pro, Mate 30, MediaPad M5 Lite 10, MatePad Pro, and LG and Samsung's devices including V30 and Galaxy S5. I use the apk on a device to connect other devices through WiFi Direct. It works fine with the devices. Here are the screenshots for the test between Mate 20 Pro and MediaPad M5 Lite 10.

Here is the short video to show the WiFi Direct apk to connect Mate 20 Pro and MediaPad m5 Lite 10. https://drive.google.com/file/d/1SKUAAgw0dif7ifshVBq8ficRv8YJN7dq/view?usp=sharing

Sorry for the late reply, thank you for your effort. We are facing an issue while connecting to the printer. – user3374790 Aug 26 '22 at 12:30
We discussed internally and removed our application Wi-Fi Direct feature support from Huawei device. – user3374790 Aug 26 '22 at 12:37
