SimpleBluetoothLibrary Data not complete

Hi, When my device reads the data coming in from the Arduino the data is coming in chopped, the data im receiving comes in very fast.

however the data should read: 03-20 21:35:18.693 30385-30385/com.bluetooth.juandiaz.bluetoothconnectivity D/data:: 122in, 313cm 03-20 21:35:18.805 30385-30385/com.bluetooth.juandiaz.bluetoothconnectivity D/data:: 90in, 231cm

do you know what could cause this?

also i tried using simpleBluetooth.setInputStreamType(BluetoothUtility.InputStreamType.BUFFERED); and simpleBluetooth.setInputStreamType(BluetoothUtility.InputStreamType.NORMAL); but is not working

im using an arduino with a proximity sensor

Thanks for the help

Mar 21 '16 01:03 juangdiaz

Hello,

Can I see your code both on the Android side as well as the Arduino side?

Thanks

Mar 21 '16 12:03 DeveloperPaul123

the code is pretty much the same as the sample. on the arduino side i have to ask my friend for it. since he is the one that did the arduino stuff. but all i know is the baud rate is 9600

Mar 21 '16 15:03 juangdiaz

Ok, the baud rate shouldn't be a factor. If you can give me the code I can try to reproduce it on my end.

How is the android code different from the sample? Or is it exactly the same?

Mar 21 '16 15:03 DeveloperPaul123

Will try to get the Arduino code. or atleast the looping code.

on the android Side is exactly the same the only difference is

...
public void onBluetoothDataReceived(byte[] bytes, String data) {
                //read the data coming in.
                Log.d("data: ", data);
...

Mar 21 '16 15:03 juangdiaz

Ok thanks, I actually think I may have found an issue:

In the BluetoothUtility.java class I have the following code in the ConnectedThread class:

public void run() {
            byte[] buffer;  // buffer store for the stream
            int bytes; // bytes returned from read()
            BufferedReader reader;

            if(streamType == InputStreamType.NORMAL) {
                // Keep listening to the InputStream until an exception occurs
                while (true) {
                    try {
                        bytes = mInputStream.available();
                        if(bytes > 0) {
                            buffer = new byte[bytes];
                            // Read from the InputStream
                            bytes = mInputStream.read(buffer);
                            // Send the obtained bytes to the UI activity
                            bluetoothHandler.obtainMessage(BluetoothHandler.MESSAGE_READ, bytes, -1, buffer)
                                    .sendToTarget();
                        }
                    } catch (IOException e) {
                        break;
                    }
                }
            //Buffered reader.
            } else {
                reader = new BufferedReader(new InputStreamReader(mInputStream));
                // Keep listening to the InputStream until an exception occurs
                while (true) {
                    try {
                        if(reader.ready()) {
                            String message = reader.readLine();
                            bluetoothHandler.obtainMessage(BluetoothHandler.MESSAGE_READ, -1, -1, message)
                                    .sendToTarget();
                        }
//                        bytes = mInputStream.available();
//                        if(bytes > 0) {
//                            buffer = new byte[bytes];
//                            // Read from the InputStream
//                            bytes = mInputStream.read(buffer);
//                            // Send the obtained bytes to the UI activity
//                            bluetoothHandler.obtainMessage(BluetoothHandler.MESSAGE_READ, bytes, -1, buffer)
//                                    .sendToTarget();
//                        }
                    } catch (IOException e) {
                        break;
                    }
                }
            }

If you notice, the object sent to the Handler is different depending on the input stream type. Then, in the BluetoothHandler in the SimpleBluetooth class I have this code to read the data:

 private BluetoothHandler mHandler = new BluetoothHandler() {
        @Override
        public void handleMessage(Message message) {
            switch (message.what) {
                case MESSAGE_READ:
                    byte[] readBuf = (byte[]) message.obj;
                    String readMessage = new String(readBuf);
                    if(readBuf != null && readBuf.length > 0) {
                        if(mListener != null)
                            mListener.onBluetoothDataReceived(readBuf, readMessage);
                    }
                    break;
    ...

In the case where you using the InputStreamType.BUFFERED, the handler incorrectly casts the message.obj to byte[] when it is actually a String. This may be causing the issue. I'll try this out something this week and post the results.

If you've forked my project, would it be possible for you to try this fix?

Thanks

Mar 21 '16 15:03 DeveloperPaul123

Awesome! Let me fork it this week and try to see if it solves the issue. I will let you know

Mar 21 '16 15:03 juangdiaz

Great thanks. If I get a chance after work today I'll give it a try as well.

Thanks

Mar 21 '16 15:03 DeveloperPaul123

Wow that was fast i was about starts looking into it! but you beat me to it. Any chance you are going to create a new tag version of it? so i can test and see if it worked

Mar 22 '16 01:03 juangdiaz

I think I may have fixed it in the latest commit. You can try it out with this dependency:

compile 'com.github.DeveloperPaul123:SimpleBluetoothLibrary:f50e73a215'

If it does in fact fix the problem, I'll create a new release.

Mar 22 '16 01:03 DeveloperPaul123

I'm re-openning this for now until it's confirmed to be solved.

Mar 22 '16 01:03 DeveloperPaul123

hey its not resolving the dependency for some reason also tried compile 'com.github.DeveloperPaul123:SimpleBluetoothLibrary:-SNAPSHOT' n didnt resolve

Mar 22 '16 02:03 juangdiaz

Looks like jitpack is still building it. The site is also acting kind-of funky so I'd give it a minute to update.

Mar 22 '16 02:03 DeveloperPaul123

lol ok, forgot about that part!

Mar 22 '16 02:03 juangdiaz

No worries. It's usually pretty quick though, not sure what's going on.

Mar 22 '16 02:03 DeveloperPaul123

You can always check the status here and look under "Commits".

Mar 22 '16 02:03 DeveloperPaul123

will do i will let you know as soon as i can test

Mar 22 '16 02:03 juangdiaz

Sounds good.

Thanks

data still coming in chopped

Mar 22 '16 12:03 juangdiaz

Are you using InputStreamType.BUFFERED ?

Mar 22 '16 13:03 DeveloperPaul123

hahah i did the test sleepy this morning! i just look at the code and forgot to add Buffered.

I will test when i get home

Mar 22 '16 14:03 juangdiaz

No worries lol. Just keep me posted.

Mar 22 '16 14:03 DeveloperPaul123

Mar 23 '16 00:03 juangdiaz

this works if i use https://github.com/johnhowe/BlueTerm ,but its not a lib like urs maybe check how they did it there.

Mar 23 '16 01:03 juangdiaz

Ok thanks for getting back to me. The only difference I can find is in the ConnectedThread class. Specifically:

public void run() {
            Log.i(TAG, "BEGIN mConnectedThread");
            byte[] buffer = new byte[1024];
            int bytes;

            // Keep listening to the InputStream while connected
            while (true) {
                try {
                    // Read from the InputStream
                    bytes = mmInStream.read(buffer);

                    mEmulatorView.write(buffer, bytes);
                    // Send the obtained bytes to the UI Activity
                    //mHandler.obtainMessage(BlueTerm.MESSAGE_READ, bytes, -1, buffer).sendToTarget();
                } catch (IOException e) {
                    Log.e(TAG, "disconnected", e);
                    connectionLost();
                    break;
                }
            }
        }

I'll make this change and push to master.

Mar 23 '16 02:03 DeveloperPaul123

If you get a chance, could you try this commit?

compile 'com.github.DeveloperPaul123:SimpleBluetoothLibrary:99e7d21a0f'

Thanks

Mar 23 '16 02:03 juangdiaz

Wow haha. That's interesting. Looks like I'm going to have to do some more testing then. I'll have to take some time to take a closer look. Do you know if you're using System.println() on the Arduino side?

Mar 23 '16 02:03 DeveloperPaul123

Wait, can you try that commit w/the InputStreamType.NORMAL flag?

Mar 23 '16 02:03 DeveloperPaul123

i will ask my friend will get back to you as soon as he tell me.

i tried with Normal and is giving me same junk. revert ur last commit.

Mar 23 '16 03:03 juangdiaz

thanks for the efforts its a kick ass lib and it will get better!!
