Other Parts Discussed in Thread: BQSTUDIO

Hi,

one of our customers has inquired if there are any differences to be expected by the different Hardware IDs of BQ40Z50-R1. Is there anything a customer should be aware of?

In particular, customer has received devices Hardware IDs 0x01, 0x03, and 0x0B.

Thanks and best regards,
Phil

Hi Phil,

The hardware ID should be 0xA3 for this device. How are they reading the Hardware ID? Is it through bqStudio?

Hi Phil,

I found out from the firmware team that the Hardware_ID command was not working correctly on older versions of the firmware and that it was referencing possibly a month code instead. If they upgrade the devices to new firmware, this command will work correctly and will report 0xA3.

Best regards,
Matt
