Hello Vadym, 

Please see the following taken from the device TRM. 

You can change the KEY_SEL0 and KEY_SEL1 bits by writing to Settings -> Configuration -> Auth Config. 

Regards,

Jonny. 

Hello Jonny,

Thanks for your reply.

Of course I had seen this document and this particular page, before I wrote this question. I also tried to find the memory address with this settings and I searched how to change it in "Battery Management Studio (bq Studio)".
So, what did you mean when you was writing "Settings -> Configuration -> Auth Config"? Where can I find it or which software did you use?

Kind regards,
Vadym

Hi Jonny,

Thank you so much. I verified 2 auth keys and it works well.

Could you tell me the default key, please?

Kind regards,
Vadym.

Hey Vadym, 

I am not sure what you are referring to by the default key, can you please elaborate? 

Regards, 

Jonny. 

Hi Jonny,

I meant value which is written by default from factory. I tried to authenticate with "000000...." and "FFFFFFF...". I didn't work. Than I written my own keys and authenticated successfully with your support.

Kind regards,
Vadym.

Hi Jonny,

OK, understood.
Anyway, thank you for support.

Kind regards,
Vadym
