Except for the carriage return (CR) and line feed (LF) separator characters which trigger an immediate forwarding no special grouping is performed. In Raw Mode the data is forwarded as it is received from the device. The parameters for (re-)establishing a Bluetooth connection as well as the preferred notification method can be adjusted in the BluePiano Settings.īluePiano provides two methods for receiving data (refer to Bluetooth Device Manager): If this is not possible, BluePiano suspends the device connection and notifies the user with a message in the notification bar.

If there are any problems with the device connection, BluePiano tries to reconnect automatically. The data is then forwarded to the target app by injecting the data into the active input-field. If at least one of the three parameters is fulfilled, BluePiano assumes the data packet as complete.

or by a delimiter character sequence (which is a regular expression).

the time required for receiving it (measured from the first byte of the packet).

the maximal number of bytes (packet size),.

Each packet is forwarded as a single unit to the target app (this ensures that - for example - all 8 digits of an EAN barcode are transferred as a single unit to the app). Received device data is grouped into packets. The BluePiano keyboard establishes a connection to the configured Bluetooth SPP device (via a system service running in the background) and waits for data. In addition to the Bluetooth capabilities, BluePiano is able to read NFC tags (if supported by the hardware) and provides a built-in camera scanner (useful for backup purposes, an external camera scanner app can also be adjusted).

Special Android-enabled bar code scanners are NOT required. Swipe input is not supported.īluePiano is able to connect to all Bluetooth SPP devices (Bluetooth client or Bluetooth server devices supporting the Serial Port Profile, RFCOMM). This keyboard supports all major input languages and keyboard layouts, provides word suggestions and listens to voice input. If activated, BluePiano replaces the currently active keyboard on your device with its own keyboard. For the target app there is no difference between user input and device input. BluePiano installs as a soft-keyboard which injects captured device data into arbitrary target apps by simulating user-input. For the target app the captured data appears as entered by the user.īluePiano is typically used for scanning barcodes with external Bluetooth barcode scanners or for RFID data collection. This new keyboard captures Bluetooth data and forwards the received data to input fields of arbitrary apps by simulating manual user input. The keyboard wedge BluePiano extends Android ® with data acquisition from external Bluetooth ® devices.
