Hi
I have a problem. Difference between capacity display on LCD BQ20Z655-R1 80% and on PC (EV2400) 0%. Can you help me?

The battery pack capacity LCD indication is OK. It is possible to write the „Remaining Capacity“ value manually (0x0f command). We wrote null „Remaining Capacity“ value.
The LCD capacity indication is goes to zerro. It is OK. After that we read „Remaining Capacity“ null value the (command 0x0f). It is OK.
We wrote 1000 mAh „Remaining Capacity value now“. LCD displays correct value, but PCs (EV2400 sw) read null „Remaining Capacity“ value constantly.
The error is possible chanched when we set BQ20z655-R1 soft reset command. After that the „Remaining Capacity“ value starts to indicate correctly (EV2400 sw).
We found that the BQ2060 and BQ40Z50-R2 have "Remaining Capacity" read-only command (0x0f). The BQ20Z655-R1 has write/read command (0x0f).
Is it possible to block this write command? (set read command only)
Thank you for your support and informations.
