I have an IMU (MPU-6050) and PIC32MX120F032B, i would like to communicate between them using I2C,
IMU is slave and it does not send ACK signal back. I have used modified pic32 i2c example code.
I have 4k7 pull-up resistor on both SDA and SCL. Please post all your ideas and solutions.

This is result of logic analyser during slave address (0b11010000) transmission: (upper - SCL, lower - SDA , I2CFREQ = 5000Hz)

I am not getting ack back from slave. Please help me.
