MPU6050 readings not working, values all 0 and mpud::MPU::whoAmI() error.... about esp32-mpu-driver HOT 4 CLOSED

Which esp32 dev board are you using?
Make sure you are connecting the I2C lines according to the GPIO numbers rather than PIN numbers.
If you try the mpu_i2c example does it work?

from esp32-mpu-driver.

I'm using ESP-WROOM-32 in a ESP32 Core Board V2 / ESP32 DevKitC.

I'm using GPIO numbers correctly as I should.

Tested mpu_i2c with no success, same error ocurring... 1sec delay the same error is printed to monitor

from esp32-mpu-driver.

The error code 0x107 means I2C reading is timing out. So the esp32 might not be receiving from the MPU6050.

Try the following:

• change the SDA/SCL to different GPIOs
• lower the I2C clock speed to 100KHz
• run an I2C scanner to scan all device addresses found in the I2C bus. See this example from I2Cbus library.

The scanner should show a device with address 0x68 or 0x69. If it does not show then you might have to re-check the wiring.

All problems solved, nothing wrong with your library!!!

Problems were with my 2 MPU-6050 boards. I've tested 2 other new boards and you examples worked well with them.

Don't know why haven't tested the new boards yet! hahah

Thx by answering me, I'll close the issue by now!!!
