Hello Jeremy,

You will not have access to read any of the data flash while the gauge is sealed. You will only be able to read the information on the bqStudio registers page (voltage, temperature, accumulated capacity (in ACC mode), battery status, etc)

Sincerely,

Wyatt Keller

Hi,

Ok, i understand.

It's possible to have a custom firmware for the BQ35100, with an access to Manufacturer Data (Manufacturer Info Block Axx) when the gauge is sealed ?
Because on the BQ35100, there is not register that i can modified and read when the gauge is sealed...

Thanks.
