Welcome to B4X forum!
B4X is a set of simple and powerful cross platform RAD tools:
- B4A (free) - Android development
- B4J (free) - Desktop and Server development
- B4i - iOS development
- B4R (free) - Arduino, ESP8266 and ESP32 development
SD: BT Printer Bluetooth
it would be nice to have the possibility to use all the links with a single library, LAn and also Serial.
Think about it, it would be a great upgrade
Just a push . This is the code I use to print for lan ESC / POS printers.
B4X:
Dim LANPRINTER As Socket 'Network library
Dim AStreams As AsyncStreams 'RandomAccessFile library
LANPRINTER.Initialize("LANPRINTER")
LANPRINTER.Connect(PIp, Pport, 0) '100=Printer address, 9100=Port number (please look up port number)
Sub LANPRINTER_Connected (Successful As Boolean)
If Successful Then
AStreams.Initialize(LANPRINTER.InputStream, LANPRINTER.OutputStream, "AStreams")
AStreams.Write(PrintTicket1(Sales_Code1).GetBytes("UTF8"))
Sleep(2000)
AStreams.Close
TMT20II.Close
End If
End Sub
Sub AStreams_NewData (Buffer() As Byte)
Dim msg As String
msg = BytesToString(Buffer, 0, Buffer.Length, "UTF8")
LogDebug("AStreams_NewData = " & msg)
End Sub
Sub AStreams_Error
BCT.Show(LastException.Message)
End SubNow you have taken away the excuse for not carrying it out
Sorry was also trying to help my freind @Xfood .
Good morning Maicon,
The library also works correctly on B4XPage. If you can't see the printers you are wrong in the manifest and / or in the permission request.
Make sure you know the latest changes required to use Bluetooth on SDK 30. (here)
Here you see the version of the example for B4xPages.
PS
In the example you sent me privately there are several errors. As I have already written to you, make sure you know how to set the manifest and how to request permissions inside a B4XPage.

ANNOUNCEMENT
Starting today, this library will be abandoned and will no longer be distributed.
After 5 years from the moment it was developed, I can say that it has run its full course and now there is a need to take a leap forward.
A new, more comprehensive Android library for ESC / POS thermal printers will be released. (here)
Unlike iOS id which only allows LAN and BLE connection with o.s. Android can be connected in 5 different ways (BT, BLE, LAN, USB, NFC) and I want to collect it in one library.
Here is a preview of the prototype I am testing

Hello, I tried your example for working with a Bluetooth printer. But I only managed to find the printer. Printing does not work. I checked this printer and my smartphone with other applications, everything is OK. I have a Xpinter XP-420B printer for printing labels. I was surprised that in this example does not have a label size setting. Can you help me set up your program to work with Xpinter XP-420B. For example, in the "print label" app, the label size is configured, but the data transfer protocol is not configured. When I use the "print label" app on the same test smartphone, everything prints out fine. Maybe someone can tell me what to pay attention to, I myself am a beginner in solving printing problems on a Bluetooth printer.
