my projecr need serial and hive 。but Pub get is error .

Because hive_flutter >=1.0.0 depends on path_provider ^2.0.0 which depends on path_provider_windows ^2.0.0, hive_flutter >=1.0.0 requires path_provider_windows ^2.0.0.
And because path_provider_windows >=0.1.0-nullsafety.3 depends on ffi ^1.0.0, hive_flutter >=1.0.0 requires ffi ^1.0.0.
And because every version of flutter_serial_port from git depends on dart_serial_port ^0.0.3 which depends on ffi ^0.1.3, hive_flutter >=1.0.0 is incompatible with flutter_serial_port from git.
So, because heavymetal depends on both flutter_serial_port from git and hive_flutter ^1.0.0, version solving failed.

How to solve this problem

Mac Version: Catalina 10.15.7, Mac mini (2018)

Forewarning that I am new to Flutter...

I've copied the same code from the example folder to use. It works perfectly on Windows, but when I try to run it on Mac I get this error:

Any help is much appreciated. Thanks!

Where can I find our more about the above error?
The program crashed when the above happened.

Hey JP - not really an issue, just reaching for help.

Been using your plugin as a guide to building my own (c++ based) plugin (also read your article on medium), but I can't figure out how you bundled libserialport as a .framework. In short, I can't find the .podspec of libserialport (which you use as a dependency in the macos podspec). I can't find it in the Cocoapods Master Repo either.

Help would be much appreciated!

Seems this issue still remains for Android #20
not sure if it's still not released for flutter_libserialport, I'm using 0.2.3 so I think that fix should have been merged. Anyway, the way I fix this is to comment out

#define HAVE_STRUCT_TERMIOX 1

in my /.pub-cache/hosted/pub.dartlang.org/flutter_libserialport-0.2.3/android/libserialport/config.h

Added the package as a plugin. When launching debug on Linux Ubuntu (20.), it is unable to find stdlib.h within linux_termios.c and string.h within libserialport_internal.h. Would you have any ideas what this might be please?

Hi,

I just saw that dart_serial_port has already nullsafety and ffi1.0.0 dependency. Can you integrate that upgrade here also? I'd like to upgrade my application to flutter 2.

When I try to call the dispose() method of a SerialPort object, the app crashes. MacOS generates the following error report:

OS Version:            macOS 12.1 (21C52)
...
Exception Type:        EXC_CRASH (SIGABRT)

Application Specific Information:
<appName>(2663,0x304647000) malloc: *** error for object 0x600002dee4c0: pointer being freed was not allocated
abort() called

This happens when I execute the following method:

Future<void> disconnect() async {
    try {
      await sendString(data: "cliStop");
    } catch (e) {
      print(e);
    }

    _reader?.close();
    port.close();
    port.dispose(); // this is the line which crashes the app.

    super.disconnect();
  }

You should be using FFI to access C libs. Example usage of ffigen with libserialport:
https://github.com/meta-flutter/ffigen/tree/jw/libserialport/example/libserialport

 final portReader = SerialPortReader("/dev/ttyACM0");

  try {
    port.config.baudRate = baudrate;
    port.config.bits = dataBits;
    port.config.parity = parity;
    port.config.stopBits = stopBits;
  } catch (e, s) {
    debugPrint("error : $e");

    debugPrint("stack trace: $s");
  }

error as below

 SerialPortError: Invalid argument, errno = 22
flutter: stack trace: #0      Util.call (package:libserialport/src/util.dart:39:7)
flutter: #1      _SerialPortImpl.config (package:libserialport/src/port.dart:335:12)

I'm currently porting an app from Java/Swing to Flutter that running on Windows 11 that communicates with devices via serial. For the most part, everything works as expected. Occasionally, however, the baud rate doesn't set correctly. No errors are reported and calling the baud rate getter after opening the port returns the intended baud rate. Measuring the baud rate with an oscilloscope shows 9600 regardless of what I actually set the baud rate to in the code. The problem persists even after closing and reopening the app, restarting my PC, swapping USB/Serial converters, and changing which USB port the converter is plugged into. Interestingly, I can resolve the issue by opening the COM port in Putty (or any other application that uses the serial port). Once I have done this, the Flutter app again works as expected (for a couple of days) before the issue arises again. I've posted a snippet of my initialization code below for reference. (This was done with flutter_libserialport version 0.2.3).

try {
  comPort = SerialPort(serialPort);
  comPort.config = SerialPortConfig()
       ..baudRate = baudRate
       ..parity = parity
       ..bits = bits
       ..stopBits = stopBits;
  comPort.openReadWrite();
 } catch (e) {
     print(e.toString());
}

I get the error Count must be in the range as soon as I write to/read from serial port on Windows 10/11. I am using SerialPortReader.

Getting this error on the first interaction is a blocking issue for our app.

I'd appreciate your help.

SerialPortReader: when is OnDone called?

When I am done with reading in OnData, I tried to call reader.close(); but it crash the app.
When is OnDone called?

Create a podspec for libserialport and push on CocoaPods?

I tried using the sample code to try and communicate with an Arduino Uno that just simply prints some string to serial port periodically. I couldn't get it to work, the data I receive are all empty. I would really appreciate any help regarding this. Thank you.

The package has been renamed to flutter_libserialport and published on pub.dev.

P.S. The package was previously called "flutter_serial_port" which conflicted with an old discontinued package by the same name: pub.dev/packages/flutter_serial_port.

P.P.S. Likewise, the respective Dart package was renamed from "dart_serial_port" to libserialport.

Hi everyone,

I'm trying to run the example of the flutter_serialport lib, but it doesn't work on the android system, only windows, can anyone help me?

Some questions:

1. Where are the API documentation? I see many in the issues section here writing commands and methods thart are not mentioned at all in this github

2. How do I send strings via the serial port instead of sending bytes?

Thanks and hope to hear from you soon.

Hello my friend! Nice package!

My name is Jhon and I'm a flutter developer.

I'm working in a desktop project that I need to check the connection and capture the weight of a precison scale connected to computer by Serial USB.

Can your package help me?

I'm seeing that the package can check the connection and show information about the Serial USB Dispositive. But the weight? Can I capture that?

Error: TimeoutException after 0:00:03.000000: No stream event
Lost connection to device

What could cause such a drastic crash?
Here is a snippet of the code

SerialPortConfig serialConfig = SerialPortConfig();
var port = SerialPort(serialPort);
print("readSerialPort: get reader");
SerialPortReader reader = SerialPortReader(port);
String resultString = "";

Try {
final timeout = const Duration(seconds: 3);
await for (Uint8List data in reader.stream.timeout(timeout)) {
          if (data.isNotEmpty) resultString = resultString + String.fromCharCodes(data);
          if (checkString == commandEndString) {
                        print("End reach\n");
                        reader.close();
                      }
          }
} catch (e) {
    reader.close();
    port.flush();
    port.close();
    serialConfig.dispose();
    port.dispose();
    return Future.error(e.toString(), StackTrace.current);
}

What went wrong?

Hello,

I am trying to use this plugin for a embedded linux flutter app. For that purpose I am using an external embedder for flutter on ARM and I provide only the bundle for the app using flutter build bundle. Everything looks fine except that there is no libserialport.so generated after the flutter build bundle command.

Do you have any idea what might caused the issue?

Best regards!

my code:

commPort = SerialPort(portName);
if (!commPort.openReadWrite()) {
  print(SerialPort.lastError);
  return false;
}

commPort.config.rts = SerialPortRts.on;
commPort.config.cts = SerialPortCts.flowControl;
commPort.config.xonXoff = SerialPortXonXoff.disabled;
commPort.config.setFlowControl(SerialPortFlowControl.rtsCts);

disable xonxoff and set flow control to rts/cts, but still canot get 0x13 and 0x11, please help me.

Hello,
I run you plugin on android no root,
I can't get the availablePorts.
This is the devices I have, and they have permission.

And if I give the path directly to new SerialPort("/dev/ttyUSER0"),
it throw permission denied , error 13.

But if I use the plugin serial_port_flutter, I can get the list.
Could you help me?
Thanks.

My Code:

import 'package:flutter_libserialport/flutter_libserialport.dart';

void main() {
  print(SerialPort.availablePorts);
}

Description of this plug-in on pub.dev:

flutter_libserialport is a simple wrapper around the libserialport Dart package, utilizing Flutter's build system to build and deploy the libserialport C-library under the hood. This package does not provide any additional API, but merely helps to make the libserialport Dart package work "out of the box" without the need of manually building and deploying the libserialport C-library.

Do I need any additional configuration?

HI, I have some trouble when I try to open serial port and write something into it on macOS. I use flutter_libserialport version 0.2.2.

My code is really simple:

final SerialPort sp = SerialPort("/dev/cu.usbserial-1420");
try
{
    if (sp.openWrite())
    {
        final SerialPortConfig cfg = SerialPortConfig();
        cfg.baudRate = 115200;
        cfg.bits = 8;
        cfg.parity = -1;
        cfg.stopBits = 1;
        cfg.rts = 0;
        cfg.cts = 0;
        cfg.dtr = 0;
        cfg.dsr = 0;
        cfg.xonXoff = 0;
        sp.config = cfg;
        sp.write(Uint8List.fromList(rc.hex.codeUnits), timeout: 100);
        sp.close();
    }
    else
    {
        Logging.info(this, "error opening serial port: " + SerialPort.lastError.toString());
    }
}
on Exception catch (e)
{
    Logging.info(this, "can not write into serial port: " + SerialPort.lastError.toString());
}
sp.dispose();

However, I have an error when openWrite method is called:

flutter: onpc: #0201 RiCommandsMap: sending NUMBER_3 to USB-RI interface /dev/cu.usbserial-1420
flutter: onpc: #0202 RiCommandsMap: error opening serial port: SerialPortError: Operation not permitted, errno = 1

There are two ports available in the system:

When I use, for example, this port in the "SerialTool" app with the same settings, it works as desired:

Could you please explain me that is the reason for such an error?

BUILD FAILED in 22s

when I set baudrate it does not work at all.

When I built the app and run on windows, I got this white screen. If I delete the lines that I used libserial, it is behaving normally. In debug mode, there is no problem but when I built and use it anywhere, it just behaves like this.

i don't know if that is issue or configuration error, but the maximum number of bytes to send is limited by 80 bytes. how we can send more than 80 bytes?

Hello everyone,

I am from Brasil and my name is Breno Santos.

Nowaday i'm using your library flutter_libserialport to work and i would like to know if is possible to change the BaudRate, how can i do that? It seens that value is fixed at 9600, i would like to use others value.
Looking foward to hear from you soon.

Best Regards!

I am getting below error while running flutter app in Android. Same project run in Windows desktop fluently.
I have tested on Android 5, 10 & 11, getting same issue.
I also tested by varying flutter_libserialport versions{from:0.2.0 - to:0.2.3}

What will be the reason behind this issue ?

Hello Friend!
I'm having trouble configuring the serial port.
When I test connecting an arduino through Putty, the Flutter serial connection works.
If I disconnect the arduino from the USB port and connect right after, the connection reads the data without sync.

My code:

          void conectarNaSerial(int address) {
            final port = SerialPort.fromAddress(address);
            port.open(mode: 1);
            if(port.isOpen) {
              port.config.baudRate = 115200;
              port.config.stopBits = 1;
              port.config.bits = 8;
              port.config.parity = SerialPortParity.none;
              port.config.setFlowControl(SerialPortFlowControl.none);

              reader = SerialPortReader(port);
              if(reader != null){
                reader!.stream.listen((d){
                  print("${utf8.decode(d)}");
                  var number = double.tryParse(utf8.decode(d));
                  if(number == null){
                    return;
                  } else {
                    valorSerial.value = number;
                  }
                });
              }
            }
          }

I must configure the serial port right after connecting, right?

Hi,

I am using your library to communicate with a serial device. I can write to the serial port, but I am only able to read from the serial port using the read() method. I can't use the SerialPortReader() to perform the same action. This is how I use it:

 /// read when response is enabled
  Future<String> readSerial() async {
     // _sp is the the serial port I am working with. 
    // This works
    print('num bytes available: ${(_sp.bytesAvailable)}');
    var data = _sp.read(_sp.bytesAvailable);
    print('data is ${utf8.decode(data)}');
    return utf8.decode(data);
    
    // This doesnot work
    log.info('reading from the serial port');
    final reader = SerialPortReader(_sp);
    if (reader != null) {
      log.info('listening to serial port');
      reader.stream.listen((data) {
        log.info('received: $data');
        return data.toString();
      });
      reader.close();
    }
    return null;
  }
}

Any help is appreciated.

P.S. It would be nice to mention in your example that the SerialPortConfig should be configured before opening the serial port. I assumed a default configuration was used and it took me a while to figure out that this should've been done. Thanks!

First of all thank you for this package.

Would like to know if it's possible to have an example for reading data from a serial port using flutter.

My goal is to use the serial port on an Android Set Top Box (N1 Max) capable of reading data from Arduino.

Please excuse if im asking a simple question
Is there a set process to installing this manually thats outside the usual add to pubspec and import steps ?

I found an error in windows:
FileSystemException: Cannot create link, path = 'D:\Work\project\Fin Monitor Arduino PyQT5\fin_monitor_app\windows\flutter\ephemeral\.plugin_symlinks\flutter_libserialport' (OS Error: Incorrect function. , errno = 1)

I got the above error.
Can someone shed some light what this error all about?
Thanks

I have been usinig it for few weeks with no problem, but today it end up with these errors:

well can someone tell me

how to read data to readable String ?

Hi I cloned the repo, jumped in /examples and executed a "flutter run" command...
The app launched, I then connected an ESP32 to USB port on my phone and tapped on the refresh button.

This happened :

I don't know about an Usb Serial permission in Android... how to solve this problem ?

Thanks in advance !

Hello team, I'm having trouble making the connection.

SerialPortError access denied error = 5

I'm using flutter for desktop, do I need to add some special permission to be able to run on windows?

Thanks

安装完cmake和ndk之后构建失败

My code is as follows, pretty basic

        availablePorts = libserial.SerialPort.availablePorts;
        libserial.SerialPort port = libserial.SerialPort(availablePorts.first);
        port.openWrite();

        var config = port.config;
        config.baudRate = 9600;
        port.config = config;

        port.config.bits = 8;
        port.config.stopBits = 1;
        port.config.parity = 0;

        port.config = config;
        final reader = libserial.SerialPortReader(port);
        reader.stream.listen((Uint8List data) {
          log(utf8.decode(data));
        });

I get an error on receiving data -

Invalid argument(s): length must be in the range [0, 4611686018427387903].
#0      _checkExternalTypedDataLength (dart:ffi-patch/ffi_patch.dart:60:5)

#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:192:12)

p.s. I have confirmed that my cables or cable configurations aren't faulty by using a native application I made and also through TeraTerm.

Edit - I am getting some data now, but its either single bytes or a byte array with all zeroes whereas the data I should be receiving is a valid byte array. I am able to get it using other terminals.

The following error occurs when I create a Windows desktop application and call Flutter_libserialport: ^0.2.3 :

[libserialport] flutter pub get
Running "flutter pub get" in libserialport...
Because libserialport depends on flutter_libserialport ^0.2.3 which depends on libserialport ^0.2.0, libserialport ^0.2.0 is required.
So, because libserialport is 1.0.0+1, version solving failed.
pub get failed (1; So, because libserialport is 1.0.0+1, version solving failed.)
exit code 1

When I ran the build for android, I got the following error.
The build environment is windows 10.
I have installed NDK(Side by side) ver21.1.6352462 in Android studio.
Building for windows x64(.exe) is no problem.
Can you give me some advice?

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':flutter_libserialport:mergeDebugNativeLibs'.

NDK not configured. Download it with SDK manager.

* What went wrong:
A problem occurred configuring project ':flutter_libserialport'.
> NDK at Android/Sdk/ndk/21.1.6352462 did not have a source.properties file

Even through updated android studio to use latest version of NDK

Hi, does this lib support the serial port hot plug? if not, could you please help to give me some suggestion about how to implement this? Thanks for your support!
