SMBus Communication with bq78pl114

Other Parts Discussed in Thread: BQ78PL114

Hi!!

I recently bought bq78PL114 EVM. Its really awesome. I connected 8s1p config and everything is working well !!!!

Now if i try to communicate with the device with a nxp controller ( through i2c ) , i am getting ACK for the following,

1) slave address+ W, -------------------------(0x16)

2)command code (0x22 -> bty chem),----(0x22)

3) slave address + R.--------------------------(0x17)

But all the data i get is 0xFF...... Instead of LION, i get all FFs.... I tried the same code with an INSPIRED ENERGY Battery, there i am getting LION msg properly. But with 114 am not getting.....

Please help me to resolve this....
