BQ27530-G1: Query on Fuel Gauge I2C communication with BQ24161

Part Number: BQ27530-G1
Other Parts Discussed in Thread: BQ24161B, BQ24161, BQSTUDIO, EV2400

Hi Team,

We are using battery charger(BQ24161B) and Fuel Gauge(BQ27530) in our design, BQ27530 has two I2Cs(one as a master and one as a slave).

Slave I2C of BQ27530 is connected to host processor and master I2C is connecter to BQ24161

So, can we access(read/write) battery charger's registers from the host processor through fuel gauge?

Also, please let us know the procedure how it could be updated with BQSTUDIO as well
