- low duty cycle bursts of 2.4GHz broadcasts
- doing a relatively constant monitoring of input (or not)
that is not obvious to me. Maybe it is obvious to you. While I would hardly say that 'low duty cycle/continuous broadcasts' is huge useful, it would allow folks to both pair and connect their sensors and computers without having to deal with (for example) spinning their wheels and cranks to check things out. And I would point out that there IS a duty cycle that makes continuous broadcasting of data irrelevant (pick your definition of irrelevant - unless it is aboslutely zero). The question is the relative power consumptions and marketing trade-offs derived from that.
Plus it would save Bontrager the effort to fix their documentation :-)
