BluePiano: A New Android Bluetooth Input Method

BluePiano Bluetooth Input Method for Android

The input method BluePiano extends Android with Bluetooth data acquisition.

This new input method provides a Bluetooth-enabled soft-keyboard. This soft-keyboard captures Bluetooth data and forwards the received data to input fields of arbitrary apps. The data appears as entered by the user (watch the video on YouTube).

BluePiano is typically used for barcode scanning with external Bluetooth barcode-scanners or for generic data acquisition tasks (e.g. to capture raw external GPS or medical device data). English, German, French, Russian and Swedish keyboard layouts are available.

BluePiano is easy to use and provides you with connectivity feedback in the notification bar. For backup purposes BluePiano is also able to scan barcodes using camera barcode scanners (using the built-in or an external camera scanner app).

BluePiano works with all Bluetooth SPP devices (Bluetooth devices supporting the Serial Port Profile, RFCOMM). Special Android-enabled bar code scanners are NOT required. HID devices are not supported.

1. Activate Bluetooth
   See also: Android Settings – Wireless & networks.
2. Discover your Bluetooth device
   Please note that the Bluetooth device must be “discoverable”. See also: Android Settings – Wireless & networks – Bluetooth settings.
3. Pair your handset with your Bluetooth device.
   You need to enter the pairing PIN on your handset. See also: Android Settings – Wireless & networks – Bluetooth settings.
4. Adjust the Bluetooth device as input device for BluePiano.
   All data received from this input device will be transformed and treated like any other manual input. You may also long tap the ?123 key on the BluePiano keyboard and then invoke Bluetooth Device Manager.
5. Enable the input method BluePiano
   In order to use the new soft-keyboard you need to enable it in Android Settings. Confirm the security question. See also Android Settings -- Language & keyboard.
6. Activate the input method
   Do this by long-tapping on any text field of any app. In the upcoming menu select Input Method and check the BluePiano input method. Use the same method to activate your default keyboard again.
7. Finished!
   Now read a barcode with the external Bluetooth device (e.g. barcode scanner). As soon as the data is received by BluePiano it is entered into the current edit field. As an alternative you may press the barcode key on the BluePiano keyboard: The built-in camera scanner is invoked, the barcode is decoded and the data is entered automatically into the active edit field.

BluePiano Settings - Manual

Configure BluePiano using the installed wizard or navigate to Android Settings -- Language & keyboard and then select BluePiano.

As an alternative you may long-press on the ?123 key of the BluePiano keyboard. In the upcoming option menu select the required function.

Keyboard Options 

BluePiano Settings

• Data Prefix
  Use the placeholders ${ENTER},${TAB}, ${BACKSPACE}, ${DOWN},${UP}, ${LEFT} and ${RIGHT} to control the cursor or input focus before the captured data is inserted into the input field of the current app. The placeholders specified above can be abbreviated with${E}, ${T}, ${B}, ${D}, ${U}, ${L} and ${R}. A multiplier specified immediately after the placeholder (e.g. ${E5}) instructs BluePiano to simulate the specified key n times (5 times the Enter key in this example).
• Data Suffix
  Use the same placeholders as above to control the cursor or input focus after captured data was inserted into the input field of the current app.
• Camera Scanner
  The default setting “Internal Scanner” reads bar-codes using the camera bar-code scanner integrated into BluePiano. If you prefer to select the camera scanner to be used each time, select Always ask. If a specific app is selected, the software always uses exactly this camera scanner app without asking.
• Search Key Function
  This entry specifies the action when the hardware search key is pressed (this key is usually marked with a magnifier symbol, it is also available on the hardware keyboard): Invoke Camera Scanner opens the camera scanner when this key is pressed (you do not need to activate the soft-keyboard beforehand). In this case the search key acts as hot-key for barcode scanning.
  Choose Do nothing if you do not want to change the default behavior of the standard search key.

Bluetooth Options

BluePiano Settings Part 2

• Manage Device
  Use this function to adjusted the Bluetooth input device. Keep in mind that the device must be paired before it can be used. See also: Android Settings – Wireless & networks – Bluetooth settings. This function is only enabled if the Bluetooth connection is not suspended.
• Suspend Connection
  Temporarily disable BluePiano Bluetooth connectivity.
• Suspend Timeout
  If a Bluetooth device is unavailable for more than the specified number of seconds (e.g. out of range or switched off) it will be suspended. If a device is suspended you can’t capture Bluetooth data with BluePiano. A notification is displayed and you need to re-activate the device manually. The default timeout is 120 seconds (2 minutes).
• Vibrate on Error
  If activated, your handset vibrates in case of Bluetooth or connection errors.
• Disaster Recovery
  Some handset models are using buggy Bluetooth stacks (firmware with Bluetooth SPP errors). This SPP bug makes it impossible to connect to a Bluetooth SPP device. If you experience this problem we recommend rebooting your phone, to restart Bluetooth manually or to instruct BluePiano to restart the Bluetooth service automatically. Please note that until now no reliable solution to this problem is available.

Android Bluetooth Reader, Keyboard Wedge

In the past few months TEC-IT developed an Android App for data acquisition with Bluetooth and TCP. The good feedback of the Android community motivated us to further enhance this app. The result: an universal data acquisition app including keyboard wedge functionality.

The app is named GetBlue. The final version is available as slightly restricted freeware as well as commercial application. Here are the highlights:

• Android Keyboard Wedge / Virtual Keyboard:
  Captured device data can be entered into any application.
• Supported Input Devices: 
• Bluetooth SPP/RFCOMM, TCP (e.g. RFID controllers), HTTP applications and camera scanners apps like the ZXing Barcode Scanner.
• Supported Data-Sinks:
  Bluetooth SPP/RFCOMM, plain TCP, HTPP via Get and Post, Google Docs Spreadsheets, File.
• Data Acquisition Proxy / Data Switchboard:
  Acquired data can be forwarded to any supported data-sink.

Universal Data Acquisition App

Use GetBlue like an universal data switchboard: capture data from a data-source and forward it to an arbitrary data-sink. As an example you can adjust GetBlue to collect data from a Bluetooth barcode scanner and forward this data immediately to a Google Docs spreadsheet (refer to the drawing).

What is a Virtual Keyboard?

A virtual keyboard replaces the standard soft-keyboard of Android. Captured data is always made available to this virtual keyboard. Thus, data acquired from a Bluetooth barcode scanner or an RFID tag can be entered into any application which is accepting user input. This works completely independent from the selected datasource and the target app.

Call for Requests!

The internals of GetBlue are very simply to extend (e.g. new protocols, new devices, ...). Just let us know your requirements. Whenever possible we will provide you with a solution. Leave us a comment or send an email to office@tec-it.com.

Free Trial!

Install GetBlue using Android Market on your handset. Search for GetBlue manually or use this link: market://search?q=pname:com.tecit.datareader.android.getblue.demo.

We are looking forward to hearing from you!

How to Suppress Duplicate Barcodes or RFID Tags with the Software Wedge?

The Problem:

Maybe you are familiar with this scenario: You are connecting a barcode scanner, an electronic scale or an RFID reader to your computer. When capturing data it turns out that the device is sending identical values multiple times. This happens if the user scans a barcode repeatedly, a scale sends the weight of the item periodically or if a RFID reader reports the value of a RFID tag at regular intervals.

The Solution:

TWedge provides a very flexible and elegant solution to this problem. The software wedge can be customized to suppress multiple, identical values easily: Just save the last data value received from the device and compare it with the current one. Forward the device data to target application only if these values are not identical. Here is the script:

The Software Wedge Script:

OnStart() is the perfect place to initialize the last received data value (sLastData) with a null value. OnStart is executed when device communication is initialized (e.g. the serial port was opened):

// This script is executed whenever communication is started.
// Use it to perform one-time initializations like opening a file or a database connection.
// message informaing the user what this sample is good for
MessageBox("This script demonstrates how to suppress duplicate data packets from a device.\n\nSometimes devices like barcode scanners or RFID controllers are sending the same data packet multiple times. This very useful feature just forwards unique values to the target application.");
sLastData = null;   // initialize with a value which is never received from a device 
nDuplicates = 0;    // set the number of duplicates to 0

OnData() is executed whenever device data is received. Compare the current data value (stored in DATA) with the last one (sLastData). In this example keystrokes are only simulated if these two values are not identical:

// Check if the current device data is identical to the last one
if (DATA != sLastData) 
{
  SendKeyStrokes(DATA);   // not identical: simulate keystrokes
  sLastData = DATA;       // set the last value to the current one
  nDuplicates = 0;        // increment the duplicate counter (for info only)
}
else
{
  nDuplicates++;          // duplicate received, just display an info-message
  NotifyInfo ("Duplicate data received. The value " + DATA + " was suppressed " + nDuplicates + " times");
}

More information as well as the script explained in this post will be available soon on www.tec-it.com.
