ANT+ 自行车车灯数据页32–断开命令（0x20）

标签：ant 32 0x20 BikeLight ANT Light data page

数据页32是从ANT+控制器发送到ANT+自行车灯的命令页，用于将其重置为未连接状态。此命令应作为来自ANT+控制器的确认消息发送。

所有ANT+自行车灯都应支持此页面。该消息中的所有字段均应按照表7-32中的说明进行设置。

ANT+ 自行车车灯数据页32–断开命令（0x20）_消息转发

7.16.1. 灯光索引
主灯应检查灯光索引，如果设置为0x01，则主灯应返回未连接状态。具体而言，应：
1、关闭其共享主频道
2、在数据页1中将其状态设置为“未连接”
3、将其灯光索引设置为0
4、停止传输数据第18页（主光通道ID）
如果灯索引设置为0x00，则主灯应在共享频道上将命令作为广播消息转发四次，然后返回到如上所述的未连接状态。

如果灯光索引设置为非0x00或0x01的值，则主灯光应将该命令作为已确认消息转发到共享通道。该命令最多应重试4次，直到收到EVENT_TX_SUCCESS。在这种情况下，主灯不得更改其自身的状态。

一旦命令在共享通道上转发，该命令将被一个或所有辅助灯接收，具体取决于灯索引值。如果灯光索引为零，则所有辅助灯光将接收该命令。如果主灯索引是任何其他值，则只有具有指定索引的主灯才会接收该命令。任何收到此命令的辅助ANT+自行车灯应：
1、关闭其共享从属通道
2、在数据页1中将其状态设置为“未连接”
3、将其灯光索引设置为0
4、停止传输数据第18页（主光通道ID）

7.16.2. 控制器ID
控制器ID字段应由ANT+控制器使用其序列号的LSB填充。没有序列号的ANT+控制器应为该字段分配一个固定值。
