Other Parts Discussed in Thread: BQSTUDIO, GPCRB
Tool/software:
On about 20 devices out of more than 1000 deployed on the field, our embedded software suddenly got measurements showing RemainingCapacity = 0, FullChargeCapacity=0 & StateOfCharge=0 despite the connected battery was fine. The battery to monitor is a +12 VCC, C20 38 Ah at 20°C. We are using the same golden file for all of the devices as we are using the same type of battery.
Restarting the device did allow to come back to a normal situation in most of the cases, BUT trying just to send the CNTL/RESET command had no effect.
We know how to detect such abnormal cases, so we try to find out what commands shall be sent to the device in order to get back to normal values.
Please can you provide some guidance ?
Many Thanks.
