MAP demo doesn't work with iPhone about myphone HOT 14 CLOSED

By building the MNS server on PC before sending the RemoteNotificationRegister request to MSE, I can now receive notifications.

Sorry for the late reply. It's been a busy week.

This is a known issue. I guess it's because the MAP demo doesn't handle the ConnectionId.

from myphone.

Not sure if that is the root cause. I used ConnectionId from OBEX connection call and still getting Response Code "D3". And "D3" is not a valid MAP response code based on the specification document.

Get ConnectionId here:

OBEXConnectPacket packet = new OBEXConnectPacket();
var buf = packet.ToBuffer();
....

OBEXPacket retPacket = await OBEXPacket.ReadFromStream(_reader, packet);
if (retPacket != null)
{
	var bytes = retPacket.ToBuffer().ToArray();
	foreach (var header in retPacket.Headers)
	{
		if (header.HeaderId.Equals(HeaderId.ConnectionId))
		{
			ConnectionHeader = new Int32ValueHeader(HeaderId.ConnectionId, ((Int32ValueHeader)header).Value);
			break;
		}
	}
}

Set ConnectionId here:

OBEXPacket packet = new OBEXPacket(
                ConnectionHeader
                ,new StringValueHeader(HeaderId.Type, "x-bt/MAP-NotificationRegistration")
                ,new AppParamHeader(new AppParameter(AppParamTagId.NotificationStatus, 1))
                ,new BytesHeader(HeaderId.Body, 0x30)
                ,new BytesHeader(HeaderId.EndOfBody, 0x30)
                //,new BytesHeader(HeaderId.Target, MAS_UUID)
                );
            packet.Opcode = Opcode.PutAlter;

from myphone.

Looks like "D3" is from OBEX specification,
No more than one Reliable OBEX Session shall exist at any time on each transport connection, which is equivalent to the L2CAP channel connection. If a CREATE SESSION command is issued while an active Reliable Session already exists, the operation shall be rejected with the Service Unavailable (0xD3) response code. If a CREATE SESSION command is issued while a suspended Reliable Session exists, the operation may be rejected with the Service Unavailable (0xD3) response code, or the suspended session may be removed and a new Reliable Session created.

from myphone.

If connection id is NOT reversed, then the response code is no longer 0xD3 but 0x90. However, no valid data is return when we continue making the Get request.

I created additional MAS functions to test. However currently the only one worked is OBEX Connect request. My fork

Why is this issue closed? It has not been resolved.

Why is this issue closed? It has not been resolved.

I was able to get remote notification to work by following changes in the Connection Id handling:

public override void FromBytes(byte[] bytes)
        {
            if (HeaderId.Equals(HeaderId.ConnectionId))
            {
                Value = IPAddress.NetworkToHostOrder(BitConverter.ToInt32(bytes));
            }
            else
            {
                Value = BitConverter.ToInt32(bytes);
            }
            
        }

        public override byte[] ToBytes()
        {
            byte[] ret;

            if (HeaderId.Equals(HeaderId.ConnectionId))
            {
                ret = BitConverter.GetBytes(IPAddress.HostToNetworkOrder(Value));
            }
            else
            {
                ret = BitConverter.GetBytes(Value);
            }
            return ret;
        }

my changes are available from my fork as well.

BTW, do you have suggestions for:

1. how to actually receive and handle the Notification? and
2. how to send message to phone?

from myphone.

1. Receive and handle the Notification

1. Establish MNS service connection (SetNotificationRegistration)
2. Once the MNS service connection is established, the MSE (phone) will send SendEvent function to MCE (PC) which contains the message handle when a new message arrives.
3. MCE (PC) send GetMessage function to MSE(Phone) to get the message content
4. Show the toast notification on MCE(PC) (For Windows 10/11, we can use this library, https://github.com/CommunityToolkit/WindowsCommunityToolkit/tree/main/Microsoft.Toolkit.Uwp.Notifications)

from myphone.

2. Send message to phone

Send PushMessage function to MSE(Phone)

from myphone.

2. Send message to phone

Send PushMessage function to MSE(Phone)

I have been working on PushMessage for couple days and no success so far. Any working example by chance? My example is attached below.

In terms of getting the notification from the phone, I understand the high level flow. The demo code has 1 (2), 3 implemented but I don't see the GetMessage been triggered. No success so far.

PushMessage OBEX object payload with no success:

StringBuilder mssg = new StringBuilder();
            mssg.AppendLine("BEGIN:BMSG");
            mssg.AppendLine("VERSION: 1.0");
            mssg.AppendLine("STATUS: UNREAD");
            mssg.AppendLine("TYPE: SMS_GSM");
            mssg.AppendLine("FOLDER:telecom/msg/outbox");
            mssg.AppendLine("BEGIN: VCARD");
            mssg.AppendLine("VERSION:2.1");
            mssg.AppendLine("N: null");
            mssg.AppendLine("TEL: 1234567891");
            mssg.AppendLine("END: VCARD");
            mssg.AppendLine("BEGIN:BENV");
            mssg.AppendLine("BEGIN:BBODY");
            mssg.AppendLine("CHARSET:UTF - 8");
            mssg.AppendLine("LENGTH: 51");
            mssg.AppendLine("BEGIN: MSG");
            mssg.AppendLine("Joey Pigza Swallowed the Key;");
            mssg.AppendLine("END: MSG");
            mssg.AppendLine("END:BBODY");
            mssg.AppendLine("END:BENV");
            mssg.AppendLine("END:BMSG");

            OBEXPacket packet = new OBEXPacket(
                Opcode.PutAlter
                , ConnectionHeader
                , new TypeHeader("x-bt/message")
                , new NameHeader("telecom/msg/outbox")
                , new BodyHeader(HeaderId.Body, mssg.ToString())
                );

I will try to implement a working demo in the next few days. I will post updates here if I make any progress.

Sounds good! I will update if I have success as well :)

from myphone.

I fixed the bmessage format and it is working with the demo code. The only thing really need the fix is the Connection Id. I have not tested receiving notification yet though.

Let's move the discussion here #5 since this issue is closed.
