I'm considering to use BQ30z55 or BQ40z50. Are they supported in Android OS 5.1?

Hi Jonathan,
bq30z55 and bq40z50 gauges are not recommended for new designs, please check bq30z554 and bq40z50-R1 instead, as for Android 5.1 support, I will check with each device expert and get back to you.

Best regards,
Hadiar
