1. overview

• ANT+ bike lights broadcast wireless information to a bike computer or similar controller, typically mounted on the bike handlebars. This information includes the manufacturer and product ID, battery level, and state of the bike light; for example on or off, and flashing speed.

碼表可以知道車燈的

(1)manufactor ( 公司ID)

(2) product ID

(3)battery level

(4)車燈狀況 (目前是 on or off)

• An ANT+ bike light controller may display this information to the cyclist. For example the controller may beep to warn the user of low battery levels at the start of a journey, and indicate to the user which light requires a replacement battery.

碼表可以主動發出警告訊號,告知哪一個車燈電量過低.

It is typical for cyclists to use at least two bike lights at the same time. An ANT+ bike light controller may connect to up to 8 bike lights at the same time using independent channels.
Alternatively the ANT+ bike light controller may use just one channel to communicate with all the ANT+ bike lights in use.

碼表可以用獨立channel 最多連接八個車燈,也可以用單一channel(shared channel) 與多個車燈通訊 ,

這一點我就不懂,如果可以用獨立channel ,為何還要shared channel ,

目前實作是獨立channel和shared channel兩者都需要 .
