BQ40Z50-R1: Battery Pack with two possible Unseal/FullAccess codes

Part Number: BQ40Z50-R1

Hi!!

I have a large number of bq40z50-R1 packs that need processing. The default Unseal and FullAccess codes have been changed on some of these packs. I have trying to unseal these packs with software.

I would think I could unseal a pack by sending the default codes. If that doesn't work, then send the revised codes. However, there appears to be requirement with the fuel gauge where some time must elapsed after an invalid code is received and the next code code accepted. This makes sense for security to keep someone from "hammering" on the pack until the codes are received.


But, my question is How much time must elapse between an Invalid Unseal/FA code and the valid Unseal/FA code?

Thanks for your help!!

Phil
