I have an arduino board that is connected to MPU6050 motion sensor and HC 05 bluetooth module. The target is to acquire the motion sensor data via blueooth into my ubuntu laptop. I have successfully paired my ubuntu laptop with HC05 bluetooth module. The data that I get from the minicom is junk.
For the arduino + MPU6050 + HC05 set up I use the code named firmware500.ino at arduino-mpu6050-hc05 data aquisition. I had modified the code to get ascii readable values as suggested by the author.
The bluetooth in the linux PC is set using the steps at : bluetooth-serial-setup-linux.
To get the serial data I tried minicom with setting 1152008N1, no flow control.
I set the baudrate on the HC05 using AT commands to 115200,0,0.
I dont understand why I am getting junk values. The author of the arduino claims that the code works fine. So I guess the error is either in the minicom setting or the baudrate setting in the HC05.
