What version of the product are you using? On what operating system?
android-serialport-api version1.1, on Android 2.3, 

Hi 
I am going through Android serial port Api and facing some problem as below


 1) When i built and deploy this serial port application on Android 3.0, ndk 5 ,cygwin 5 and Window Xp enviroment then its work properly

 2) but when i tried to de built and deploy on Android 2.2 or lower version then i m getting error below 
    java.io.IOException: Error running exec(). Command: [/system/bin/su] Working Directory: null Environment: null

      I Cretaed AVD 2.2 from commnand line and nothing i changed in any other place and deploy then getting error above

    I set the permission also from cygwin to dev/ttyS2 but didnt work 
can you please tell me what i am doing wrong ?

          Thanks in Advance

What steps will reproduce the problem?
1. Plug Arduino into USB port on the A500 (HC 3.2.1 with Honeylicious ROM)
2. Open up sample application
3. Select the only port that will open
4. Set the Baud to the correct baud (9600)
5. Listen on port
6. Doesn't receive anything or send anything

What is the expected output? What do you see instead?
The Arduino's TX and RX LEDs should light up when TXing and RXing. Instead, 
only the power LED lights up.  Also, the sample app should show some data from 
the Arduino, right?

What version of the product are you using? On what operating system?
Android Honeycomb 3.2.1 with Honeylicious on an Acer A500 (rooted, obviously)

Please provide any additional information below.
Is it a driver issue with the serial adapter on the Arduino or an issue with 
the Android side?  I'd LOVE to have a serial monitoring application that works 
on Android.

Thanks!
Chris

hello. again...

i don't know your e-mail.

so, i'll write here. and simply.

base source code is this android-serialport-api.

and only changed SerialPortActivity.java file.

--- original source ---------------------------
private class ReadThread extends Thread {

        @Override
        public void run() {
            super.run();
            while(!isInterrupted()) {
                int size;
                try {
                    byte[] buffer = new byte[64];
                    if (mInputStream == null) return;
                    size = mInputStream.read(buffer);
                    if (size > 0) {
                        onDataReceived(buffer, size);
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                    return;
                } catch(Exception e){    }
            }
        }
    }

---------------------------------------------------
----- and changed ---------------------------------
private class ReadThread extends Thread {

        @Override
        public void run() {
            super.run();
            while(!isInterrupted()) {

                try
                {
                    Thread.sleep(1000);
                }catch(InterruptedException e){      }
            }
        }
    }
---------------------------------------------
just added
     Thread.sleep(1000);

and try to send '1' -- 600ms lather --> '2' -- 600ms later -> '3' ....~

then this source can't receive all of char.

this source will received '1', '3', '5'....~

What steps will reproduce the problem?
1. Open project in eclipse
2. Install it from eclipse
3. Start the console application
4. Edit the source and install again it from eclipse

What is the expected output? What do you see instead?
Uninstall->install->run, but the uninstall freezes the machine when
the app is running

What steps will reproduce the problem?
1.I am able to read n write into the file on an SD card in android using the 
below code



        try {
            File root = Environment.getExternalStorageDirectory();
            if (root.canWrite()){
                File gpxfile = new File(root, "gpxfile2.gpx");
                FileWriter gpxwriter = new FileWriter(gpxfile);
                BufferedWriter out = new BufferedWriter(gpxwriter);
                out.write("Hello world");
                out.close();
            }
        } catch (IOException e) {
            Log.e(TAG, "Could not write file " + e.getMessage());
        }

But when I tried to implement the same for reading & writing from serial port 
using android serial-port-api i was not able to make it as this is very 
critical & as am new to android development,
could any body please help me in modifying the android serial-port-api in such 
way that am able to read n write from serial port using android serial port api


What is the expected output? What do you see instead?
To edit the android serial port api for writing & reading data into
the file using java file operations such way that the data from serial
port is directly written into the file & read from the file on an SD
card


What version of the product are you using? On what operating system?
Android 2.3.3

Please provide any additional information below.

What steps will reproduce the problem?
1.Install .apk from downloads to IGEPv2 board(beagle board clone)
2.App runs successfully, can detect ports(ttyS0,ttyS1 and ttyS2) even can set 
baud rate
3.Crashes when I try to open console, loopback or send 01010101. :(

What is the expected output? What do you see instead?
Crashes on all port 

What version of the product are you using? On what operating system?
Android 2.2 froyo and v1.1 of app.

What steps will reproduce the problem?
1. Download & Install SerialPort_1.1.apk
2. Run app on same hardware (Freescale MX51-BBG) 2.3.7 (it fails) vs 2.2 (it 
passes)
3.

What is the expected output? What do you see instead?
Transmit data emitted on 2.2 (Froyo) and 2.3.7 (Gingerbread).
No Receive data (in Console: reception widget) - ever.

What version of the product are you using? On what operating system?
Downloaded and ran latest SerialPort_1.1.apk from this site.

Please provide any additional information below.
In debugging custom app running serialport lib I notice in debugger a new msg 
in ReadThread, mInputStream fileSystem;
  in Froyo used to be: "OSFileSystem (id...)"
  in Gingerbread it's: "BlockGuard$WrappedFileSystem (id....)

(currently researching this...)

But since your SerialPort_1.1.apk behaves identically w/o a ReadThread - this 
seems most likely to be meaningless.

Why work on Android 2.2 and no Rcv on Android 2.3.7?

Please add support for setting the stop bits and parity. 

What steps will reproduce the problem?
1.I send serial data from the PC and to SerialPort.apk above AM35X Development 
board， but the first time will lose the first byte and back to the PC side, 
the second time in order to receive all the bytes,I want   the  reasons is 
Software or hardware.

port first" even though i already did...

how to fix this problem?

thank you

What steps will reproduce the problem?
1.I am sending random data from android to UART and observing the output of 
serial port in another laptop. The problem is that the random is received from 
the serial port with more delay..Why there is delay between each data sent from 
UART. How to reduce delay between transfer?
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Android SDK Tools: rev 8
Emulator AVD: API 2.2

I'm using the SVN version and a Nexus One with ftdi_sio/pl2303 usbserial 
converters.
When started for the first time after a reboot, ConsoleActivity works fine. But 
when I leave the activity (whether SerialPortActivity.onDestroy() is called or 
not) and restart it later, only sending data works, and no data is received 
anymore. What may be the problem here?

What steps will reproduce the problem?

1. install SerialPort_0.7.apk (CM5 already has serial port enabled)
2. start SerialPort example, configure it
3. start the console example, it will fail with "The serial port can not be 
opened for an unknown reason"


Problem seems to be in line 96 of SerialPort.c:
> fd = open(path_utf, O_RDWR | O_DIRECT | O_SYNC);
The device file is open()ed using O_DIRECT, which fails on my Dream/CM5.0.8.
Removing O_DIRECT works, but shows another Problem:

At least at my CM image, there seems to be a divisor of 4 configured for the 
ttyMSM2 port. So, when configured to 4800 baud, it will actually use 1200 baud.

This is bad, because from all standard rates, only 1200(4800), 2400(9600) and 
9600(38400) can be used.

What steps will reproduce the problem?
1. Got o the main screen
2.Set the device and baud rate to /ttyUSB0 and 9600
3.Click on the Console button. In the top part only the cursor moves, showing 
that it is receiving something but it does not display the readings which are 
received.

What is the expected output? What do you see instead?
The temperature and brightness readings from the X-stick should be displayed.

What version of the product are you using? On what operating system?
Android 2.3 on Raspberry Pi

Please provide any additional information below.
We are using Raspberry Pi. A X-stick is connected to the USB port of the 
Raspberry Pi which has readings received from a wireless sensor. We have 
compiled the kernel such that it shows /ttyUSB0, We have set it up with 9600 
baud rate. Once clicking on Console, the cursor moves showing that it is 
receiving something from the X-stick but the readings are invisible. Please can 
someone help?

What steps will reproduce the problem?
1.lunch the app
2.choosing to send a command using the mFileOutputStream.write
3.the activity is on the background

What is the expected output? What do you see instead?
the activity has to stay in the foreground not in the background

What version of the product are you using? On what operating system?
I workin on the android 2.3.4 gingerbread on an i.MX53 board

Please provide any additional information below.
the application sending the command without any probleme. but it goes to 
background

What steps will reproduce the problem?
1.download .apk file and try to install it on ICS device (NOVO 7 Paladin) 
2.Installation ends with "file corrupt" error.


What version of the product are you using? On what operating system?
Android 4.0.1 ICS and SeialPort-api r46

Please provide any additional information below.
I am not sure if this is an issue with the ICS or the device.

any suggestions? anything I can test.

Hi,I try to build a communication between the tablet PC and the MCU with PL2303 
chip. My tablet PC use Android 4.0 system. My MCU is a 51 series. I choose the 
setting '/dev/ttyUSB0' and 'Baud rate 1200' on tablet PC. I tried the 
'Loopback' and 'Send 01010101', but the MCU can not receive any data. Does 
anyone know what is the problem?

      {  RI=0;      
         b=SBUF;    
         P0=b;
       }  
 } 
}

What steps will reproduce the problem?
1. Build the Project using eclipse in Ubuntu
2. Install the APK using adb
3. Run the serial port program and click setup, then click device

What is the expected output? What do you see instead?
I would expect to see a list of tty devices.  I'm not really sure as 
nothing shows up?

What version of the product are you using? On what operating system?
I am running on Android 1.5 on my own prototype Hardware.  I am using the 
standard android build system.  My system functions very well.  
My Linux kernel is 2.6.28.  
My build system is an Ubuntu Machine using eclipse.  The build process went 
smoothly.  
Please provide any additional information below.

I know there are some unknowns because you don't know what hardware I am 
using.  It is a custom platform based on Marvell PXA310 CPU.  
How does the APK find the list of serial devices?  is it possible it is 
looking in the wrong place?

I have been using ttyS0 as my console port.  I created a build with ttyS1 
and my original com port no longer works and the app still does not show 
any devices.  
Any help on getting it to see my tty devices would be appreciated.

Thanks

What steps will reproduce the problem?
1. Try to set settings for parity, data bits and stop bits
2. Could not find any method to set parity.
3.

What is the expected output? What do you see instead?

There should be a way to set parity, data bits and stop bits for serial port 
connection.

What version of the product are you using? On what operating system?
Android 2.2

Please provide any additional information below.

I could not find any method/way to open a serial port connection with parity, 
data bits settings.

What steps will reproduce the problem?
1. Connect the Android Phone to something that sends bytes over the serial
port occasionally, e.g. a sensor or another Android.
2. Start the Console in the SerialPort activity.
3. Wait for reception of the incoming bytes on the Android.

What is the expected output? What do you see instead?
- Most bytes do not appear on the Console in the Recepton field. Only
occasionally one appears, without a defined pattern in what comes through
or not.

What version of the product are you using? On what operating system?
- Android Dev Phone, with Cyanogenmod (both on 4.1.999 and 4.2.5), using
the SerialPort_0.7.apk. No other apps installed.

Please provide any additional information below.
- I have checked that the phone is capable of receiving messages by using
the Loopback test, and by sending messages to itself using the Console. It
seems like the phone is only listening when it is sending something itself.

What steps will reproduce the problem?
1. Error:- please configure your serial port first
2.
3.

What is the expected output? What do you see instead?
- still get this error even after I set the port and baudrate

What is flag in serial port constructor ?

the reason is GPS.

GPS keep steal uart data.

so we need to off GPS(android setting menu).

gl :)

while(1)
{
    iLen = m_cInputStream.read(bytesBuffer);

    if(iLen > 0)
    {
        // Toast Show
    }


    Thread.sleep(10000);
}

example source for explain.

and i will send '0' -> then, app will show toast [ 0 ].

and i will send '1' directly -> If, it is ideal situation, then 10second after 
showing toast [1].

but didn't showing...

where is my '1'...??? why missing byte?
