Part Number:BQ34Z100-G1
Using a bq34z100-G1 fuel gauge, having all sorts of issues....any commands using Data Memory screen on bqStudio are ignored. What works: it does report a battery voltage, and if the battery voltage is changing, it registers that. When trying to disable external temperature sense, it ignores the command in Data Memory screen. Also, when a command is issued to change from default values such as number of cells from 1 to 4, that command is ignored. When a change is made to voltage divider value, it is also ignored.
I2C bus looks fine SCL and SDA...pull-ups etc.
There is something fundamental I am missing. What else one has to do to get a fresh bq34z100-G1 to work?
Reading the literature, datasheet, app notes...all points to going to Data Memory Screen, make changes and it should be configured away from default settings.
Any help would be greatly appreciated.
