Hi sir,

I am confirming the checksum.

Will it be updated in during usage?

If so, what conditions would cause it to be updated?

Please help me answer.

Thanks!

Hello,

Yes the checksum will be updated during usage. Essentially because of the way that the checksum is calculated, it is updated each time the data memory changes.

Jonny.

Hi Jonny,

Good answer.

Then, could you help me check about Ra max delta?

Is it need to be adjustment before golden learning ?

If set to default, what impact ?

Hello,

You should be able to use the default for this value, but if you wish to edit this value please refer to the following image taken from the BQ27742-G1 TRM.
