Problem with DFRobot BNO055 + BMP280 and ESP32
silvia.verch 2019-05-17 15:24:02 5734 Views3 Replies I have a problem with modul Gravity BNO055 + BMP280.
The data of BNO055 will not be read.
1. My Hardware
- ESP32 DevkitC from AZ-Delivery
- Gravity BNO055+BMP280 intelligent 10D OF AHRS SKU SEN0253 from DFRobot
2. IDE and Libraries
IDE : Arduino V1.8.9
Modul : Gravity BNO055+BMP280 intelligent 10D OF AHRS SKU SEN0253
Libraries : Original from DFRobot wiki page BNO055 Library and BMP280 Library
3. Test I2C Interface
For the test of the I2C interfaces I use the sketch “I2CScanner”.
And the scan result shows this picture.
It is all ok. In channel 2 the I2C address 76 = BMP280 and address 28= BNO055.
See the pictures below!
4. Test BMP280 Sensor
For the test I use the example "read_data" from the DFRobot_BMP280-master.
You can see, it works fine.
First the I2C Scan Interface one and two und than read the data from BMP280.
See the pictures below!
5. Test BNO055 from “DFRobot_BNO055-master” -> examples -> readData
And now my problem. The module BNO055 is not recognized. Why is that?
The Arduino project file : ESP32 Projekt.zip
The zip file contains all three Arduino projects
I2C scanner, BMP280 and BNO055.
See Attachment!

This sketch does not work.
The Scanresult shows I2C addresses 28 and 76.
Serial Port send the message
"bno begin faild"
"device not detected"
