how to access the magnetometer

[PatelKishanJ]

hello kriswiner,
actually i have used mpu9250 library and i have got reading of the accelerometer and gyrometer data,but when i tried to communicate with mpu9250,i could not.
Means that after reading data of accel. and gyro ,i have enable the bypass_i2c.then when try to something write/read with magnetometer_address(0x0C) and send start_condition of i2c ,it could not get acknowledgement.

If you perfrom an I2C scan, which devices show on the I2C bus after enabling bypass?

thank you.
actually because of some hardware issue,it cause communication problem with the magnetometer.
now,i can get all data,see below. are all right?

ax ay az (meter/second square)
-0.02 -0.01 -0.32

gx gy gz (degrees/second)
-0.33 29.65 -0.00

mx my mz (milliGauss)
-461.03 -275.13 5563.25

temperature=23.19 degrees centigrade

The mag values seem about 10x too large, and the gyro values are very large indeed if the device is at rest.

okay.so,what should i change?..
any specific setting or anything..
and i have 1 question that how can i sure that raw data is right?..any hint?..

[kriswiner]

check units
