Android Question AsyncStreams with bluetooth barcode reader

[GaNdAlF89]

Hi, I want to read data from a barcode reader device. The barcode reader is correctly connected with a serial object. After this connection I do this:

AStreamReader.Initialize(BTSerialReader.InputStream,Null,"BTAStreamReader")

but nothing happens when I read a barcode: neither BTAStreamReader_NewData nor BTAStreamReader_Error event is raised. Where is the problem? Thanks

Make sure to also handle the Terminated event.

If NewData is not raised then the barcode is not sending anything.

This code is not in a static code module, right?

When this event will be raised?
I added the Terminated event, but there is no difference, it doesn't work..

This code is not in a static code module, right?

Yes, the code is in an activity module

When this event will be raised?

It is raised when the connection is terminated.

No event is raised, but the connection is established. I tried also with AsyncStreamsText but I have the same problem. Why?

Edit: If I set the focus in an editText, the text is written.

Your barcode scanner is acting as an alternative keyboard. It is probably not sending any data through the SPP channel.

I set it in SPP mode with its manual, reading a qrcode in particular. In this manual there is no other to do for SPP connection. What do you think I have to do to fix it? Thanks

Not sure. Assuming that you are handling the event correctly then the barcode isn't sending any data.
