Interpretation of Firmware version for Bq27510-G3

Other Parts Discussed in Thread: BQSTUDIO

In trying to determine which versions of hardware and firmware that are implemented on our company's fuel gauges, the GetFirmwareVersion and GetHardwareVersion commands were implemented.  The values that were produced do not seem to directly correlate with the expected values for Firmware Version.  As such we request a translation between values returned by the fuel gauge and the actual hardware and firmware values:

Ex:

New chip, presumed to be a G3 reads FirmwareVersion : 1024 and HardwareVersion: 185

An older chip reads a value of 217 for the Firmware Version, which also doesn't seem to correspond to any of the released versions.

    Hi Joshua,

    You can see the firmware version in BQstudio by sending the command "FW_Version" (explained in Chapter 2.1.3 of the TRM)

    Do the values you are reporting above come from your host? One thing I have noticed is your firmware version says 1024, which is the decimal for x0400

    The HW_Version command is not available on the G3 variant.

    Best,
    Justin
