mpu6050 to read FIFO data

I'm using MPU6050 sensor and I can read the FIFO buffer counter value but I could not read FIFO buffer data. Can any one help me to find it out. If so it would be very helpful to me

Are you trying to write the code yourself ? That is not easy.
The i2cdevlib uses the FIFO, you might look into that library to see how it is done.

i2cdevlib website :

The file that reads the FIFO : i2cdevlib/MPU6050.cpp at master · jrowberg/i2cdevlib · GitHub

The getFIFOCount() gets the amount of bytes that is in the FIFO buffer.
The getFIFOByte() and MPU6050::getFIFOBytes() retrieve data from the FIFO.
