I need to build app for to send PDF file on ZD410 printer using bluetooth connection. Is there any solutions to handle it? Any information will be helpful, thank you.
UPDATE:
here is my code from test application
try { mmSocket.connect(); } catch (IOException e1) { android.util.Log.e(TAG, e1.toString()); try { android.util.Log.i(TAG, "Trying fallback..."); mmSocket =(BluetoothSocket) mmDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class}).invoke(mmDevice,1); mmSocket.connect(); android.util.Log.i(TAG, "Connected"); } catch (Exception e2) { android.util.Log.e(TAG, "Couldn't establish Bluetooth connection!"); try { mmSocket.close(); } catch (IOException e3) { android.util.Log.e(TAG, "unable to close() " + mSocketType + " socket during connection failure", e3); } connectionFailed(); return; }}
“java.io.IOException: read failed, socket might closed or timeout, read ret: -1” exception appears while i'm trying to connect my android device with Zebra ZD410 printer.
This code works well with Epson printer and some other devices, but not with zebra ZD410 printer. What can be a reason?

Hi Dimitriy,
First make sure that the ZD410 printer and pair with your Android device by itself as to make sure that the printer is capable of a Bluetooth connection with the device.
As far as having your app communicate via Bluetooth to the printer, we recommend developing your app with the Link-OS™ Multiplatform SDK | Zebra
It contains Andoid APIs that allow for Bluetooth communication with Zebra printers.
Also, since you are printing a PDF, I wanted to ask if you were able to convert it into an image and wrap it in ZPL. The PDF would need to converted into ZPL in order for it to print on the ZD410.

Thanks for reply Greg
I checked direct Bluetooth connection with my Nexus 7 and it's works well.
Then i downloaded and installed Link-OS SDK as you said, but unfortunately it's still doesn't work, i was trying to use demo app provided with installation package "ZSDK_DemosAndroid".
Here is what i got with "Printer Status" function
