HX711

Hi I am trying to get data from a hx711 amplifier via a arduino, bluetoothed to app inventor. The hx711 is a digital amplifier and sends the signal using the serial.print function. I think this is sending the data as an ascii value. App inventor will display the data in a text box but when I try to use the drawline component it crashes. Would I be best changing the arduino code so I can use the serial write function or should I convert the data in app inventor into something I can use with drawline?
