Please let me know that scanner is not working properly it is missing data from serial port. Is there any other method to obtain values from serial port from Arduino? I am using Accelerometer ADXL335 and Arduino sending 3-axes values, I want to attain on my Java program. If anyone please guide me how to resolve it.
