Your waves looks good, could you specify what do you expect to get?
Regarding the sensor not being recognized, are you sure you are using the right I2C address for the sensor you are trying to access? These are the addresses for the devices in that sensor.
If the address is correct, please attach the code you are using.
Thank you for your reply, I have solved the problem. The problem in the voltage, In the datasheet of GY-86 said: VDD is under 3.5v , and VDDIO is 1.8v - VDD + 0.1 .
I have connect to the 3.3V voltage on Arduino board. but voltage of IO is still 5v. So no matter how hard I try in vain .
Now I have changed foot of J2 to 3 position. It is work.
Thank you all the same.
