4 minute issue

Richard Brisk

I think that my bq27425 takes 4 minutes to accumulate data because the CFGUPMODE flag is set. The spec says that it either gets reset in 240 seconds (ie, 4 minutes) or via a SOFT_RESET command. The problem is, the SOFT_RESET command does not reset the CFGUPMODE flag. How can I reset the flag?

Hello Richard,

That is strange.

Are you sending 0x42 to 0x00?

Thanks

My viewing procedure was wrong. The SOFT_RESET is working properly.

My problem may be related to the fact that the CHG and the SOC1 and the SOCF flags are set in the flag register.
I assume this is not healthy, but I do not know how to change the situation.
I further assume that it has something to do with my DataBlock values.

Do you have thoughts or suggestions of things I should try?
