bq40z50-r1 AtRateTimeToEmpty

I'm getting 65535 in every readout. AtRate has been set, AtRateTimeToFull updates perfectly.

What am I missing?

The manual says "NOTE: 65535 indicates not being charged." which i guess mean _dis_charged?

But its 65535 if teh pack is idle, if charger, or if discharged.

Thanks,

William,

The manual note under AtRateToEmpty should read "65535 indicates not being discharged". Could you share what values you have for AtRate(), DesignCapacity() and the discharge rate you are using?

William,

To follow up, AtRate treats positive values as "charging current" and negative values as "discharging current". In order for AtRateTimeToEmpty to update its value, AtRate needs to have a negative number.
