BQ27Z561: Unexpected result for "Verify Existing Firmware Version"

Part Number: BQ27Z561

Hi team,

When I send the following command to compare the version of the gas gauge, I don’t receive a matching result. Is this expected? 

 

From DFFS File:

;--------------------------------------------------------

;Verify Existing Firmware Version

;--------------------------------------------------------

W: AA 3E 02 00

C: AA 3E 02 00 15 61 00 04

 

What I received:

00 FF FF 99 0B

Thanks,

Michael
