this is my output, I could get data of IMU in arduino ide, my IMU is MPU6500, I read from several articles that MPU9250 registers have the same construction with MPU6500, please help me to understand what error is this, Thanks)

@Narek-939 you may have to adjust the bus number for your sensor. The LinuxI2cCommunicator allows to specify the bus number in the constructor. The default value is 1 which may not be the same as in your case. You can pass the number in this line: https://github.com/hiwad-aziz/ros2_mpu9250_driver/blob/482aa093c36dae0303a103c3d6e9296151146f65/src/mpu9250driver.cpp#L13

See the constructor for reference: https://github.com/hiwad-aziz/ros2_mpu9250_driver/blob/482aa093c36dae0303a103c3d6e9296151146f65/lib/i2c/src/LinuxI2cCommunicator.cpp#L15C7-L15C7

I fixed that error but after that I am encountered to this
