Connect Phidget RFID 1024 to android tablet otg/micro usb

[sjamientje]

Hi guys,

I'm new on this forum so first a hello from the Netherlands

Here is the thing. I'd like to connect the PhidgetsRFID 1024 to a tablet. It is a pretty custom tablet: rockchip-pt201 (micro USB).

I have an OTG cable connected. So far so good. The device is also "recognized" in Eclipse. I'm using this code snipped for that.

manager = (UsbManager) getSystemService(Context.USB_SERVICE);
deviceList = manager.getDeviceList();

When i instantiate the RFIDPhidget and set setAntennaOn(true) it throws the error: Device unattached.

Unfortunately my tablet doesn't have the correct permissions. All the efforts to push the android.hardware.usb.host.xml file have failed, no root access

So i'm looking for a solution, a different tablet, which will work instantly. Does any of you know which tablet will work if any (with micro USB)?

Regards,

Chamin Hardeman

The tablet that we use here is the Asus Transformer TF101 with the keyboard dock that has two USB ports, running Android 4.0.3.

I would expect a permissions error instead of a "Device unattached" error, which is usually a sign that the Phidget hardware has not had enough time to initialize after the object has been instantiated and opened.

If you are using attach events, you can call setAntennaOn inside the event handler.

If you are not using attach events, after you call open on the RFID object you will need to call waitForAttachment(int) which is a blocking call that waits until the RFID hardware has been properly initialized.

If you haven't already seen, we have a few simple Android examples.

OK i've rooted the device and added the xml's to system/etc/permissions

I'm using the HelloWorld example and get the following output:

System.out.println("Device: "+device.getDeviceName()); <- RFID Read Write.

1) Does that mean that i am able to use the usb device directly connected to the tablet?
2) I'm not able to implement a attachEvent , can you send a snippet?

1) The HelloWorld example simply lists any connected devices. Since it detects the RFID device

2) The examples are located here: http://www.phidgets.com/docs/OS_-_Android#Quick_Downloads. There is an example for a network attached PhidgetInterfacekit and for a USB connected InterfaceKit. Follow the sequence for adding an AttachListener to the device object, as well as the Runnable class, AttachDetachRunnable.

Hi erik, we've got the HelloWorld working, hello and goodbye are showing. But now we're stuck on the device (Phidget) - rfid (RFIDPhidget) part :S struggling...

Can we do something like typecast the device to RFIDPhidget?

We've got it! \o/ Thanks!
