problem data I2C to sensor GY955/BNO055 (China)

Question

I want to ask, I have a problem when running the Arduino sensor, I can't output data, but it's detecting that the sensor address has been paired.
Like I2C has a problem or locks it.

Last night it worked only because my twin sensors tried another with the same program after I compiled and uploaded, I see the serial monitor is only a detection sensor, but it doesn't display data, so the pitch evaporates and the roll data is 0.0,0.

There seems to be a problem with i2c: the data does not come out, it only detects the sensor address but the contents are all zero. Have you ever experienced this?

This initially worked, because the sensor was the same and I tried it with the same program after reading GY 955 / BNO055 on Euler_streaming it only showed zero per axis.

This is code in the bread board

• Jot: Can someone find a schematic of the gy955?
• chrisl: How do you know, that the sensor was found at the address? What library are you using (link)? Is the address defined in the BNO055_support.h?
• Jot: Hari_Murti, did you connect the vcc of the module to the 3.3v pin or the 5v pin of the arduino mega 2560?

Answer 1

I had the same problem with the Adafruit library. When a Chinese module is used the id needs to be specified in the constructor like this:

Adafruit_BNO055 bno = Adafruit_BNO055(55,0x29);
