connect: read failed, socket might closed or timeout, read ret: -1 code 71248565

i hade this error in my xPrinter Xp-p323B connect with pin code 0000;

When I try to connect to a printer with a pin code, the connection is closed immediately before the pin code is entered

W/BluetoothAdapter(17303): getBluetoothService() called with no BluetoothManagerCallback
D/====> print: (17303): connect: read failed, socket might closed or timeout, read ret: -1 code 42882209
I/flutter (17303): result status connect: false
I/flutter (17303): state conected false

i'm using the example of this package

It would be great if you could add new features

This feature allows the connection to be made without the user having to write the device's PIN, being set programmatically with the connectWithPin() method, being necessary to pass the pin of the device to be connected (Android only).

Example:
await device.connectWithPin("1234")

Thanks I will look for a device that requires pin to try to implement the option.

Thank you. I appreciate your interaction
Can you do me a favor please ?
can you add a timeout argument to connect function as optional parameter just for avoid timeout
As long as the pin number is not added, please add connect with timeout thanks
String mac = "66:02:BD:06:18:7B"; final bool result = await PrintBluetoothThermal.connect(macPrinterAddress: mac,timeout:35);

That's another good suggestion, to set the waiting time, I had thought about that, thanks.
