Part Number: BQ35100
Other Parts Discussed in Thread: EV2400

Tool/software:

We are a company working on meter flow, and currently we are investigating the fuel gauging IC BQ35100.

I installed the BQtudio and we have the evaluation kit of the IC and the EV2400 to validate it, but we faced the following issues:

- when I send the commands NEW_BATTERY it respond with WriteMACReadBlock communication error :First two bytes of MAC response read from device does not match MAC command sent, although I follow the procedures stated in the EOS application note.

- the batteries which we will use in our products are not stated in the chemistry ID list (We are using TeKCell CR17450 and TeKCell SB-C02)

We appreciate if you could give support to us

Thanks
