That's definitely possible, however to achieve such a functionality you'll need to change the communication protocol, and therefore edit the firmware running on the device.
The source code for the firmware is available at: https://github.com/BITalinoWorld/firmware-bitalino
It can be edited using for example Atmel Studio: http://www.atmel.com/microsite/atmel_studio6/
You're free to change it to your preference and reprogram the device with your custom firmware. For the time being, BITalino can only be reprogrammed using an ISP, such as:http://www.atmel.com/tools/avrispmkii.aspx?tab=overviewhttp://www.arduino.cc/en/Tutorial/ArduinoISP
We hope you've found this information useful for the goal you are pursuing. Do let us know in case you have any additional questions... we're looking forward to hear about your cool BITalino-powered projects
