hello to all,

i'm working on I2C Based Communication Device bq27742-g1(Texas Instrument) Battery fuel gauge which is Slave Device address is 0xAA. i have put the pull up resistor of 10 k.

in this i'm using Kinetic series cortex m4 micro controller as Master device. micro controller successfully working with another I2C device.

Bq27741-g1 Battery fuel gauge i have tested on MSP430 launchpad board using I2C scanner it is working on Launchpad board.

i have attached screen shot of CRO Signals (SDA(PINK) SCL(Yellow)) of I2C Device in the 9th clock pulse of SCL when SDA have undetermined state.why this is occur at this level . in this having issue of pull up resistor .??
