Hi Sir,

    I only find one example for CYW20729 hidoff mode.

    The lowest sleep current is 0.7mA(3.3V) more than I expected.

    Can you please advise how to improve? Thanks.

As the BCM20719/29 and BCM20735 and BCM20706 are not released into the Broad Market yet, please use MyCases and the Cypress internal tracking system for support related to these two families.
