SerialPortError (SerialPortError: Permission denied, errno = 13)

[workoutand]

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?

Hi, perhaps the discussion at https://github.com/jpnurmi/libserialport.dart/issues/3 helps

Hellow, I saw this thread but I didn't understand where those directories came from

“ Permission denied, errno = 13 ” Is there a tutorial on how to solve it?

I have the same problem

This lib should be updated to use the new android permissions handling, see https://github.com/altera2015/usbserial/blob/master/android/src/main/java/dev/bessems/usbserial/UsbSerialPlugin.java

That lib, usbserial, could be used instead of this one until it's fixed here I think.

I make it work using the native implementation of Flutter. in native use this in gradle io.github.xmaihh:serialport:2.1.1

is it possible for you to put the steps on how you solved it, unfortunately, I have zero knowledge of the native structure.

[eldhosekm]

you can use MethodChannel to communicate to native here is the sample. You will get the callback in flutter from java or kotlin.

https://medium.com/@iiharish97ii/method-channel-in-flutter-bridging-native-code-and-flutter-with-two-way-communication-788d1e91c8c1

then you write the code in native (java or kotlin) using this library( io.github.xmaihh:serialport:2.1.1) to communicate with serial port.

Having the same problem while running flutter on Linux. Using sudo solved it.

We put permission handling in todo. Activity is tracked in #76 Closed
