Nut 有3个LED灯用来指示其工作状态
状态灯颜色 | Nut状态 |
---|---|
浅蓝色 | 启动 |
红色闪烁 | 配置模式 |
黄色闪烁 | 更新固件 |
绿色闪烁 | 尝试连接网络 |
蓝色闪烁 | 尝试连接云平台 |
白色闪烁 | 已连接云平台 |
Nut 有2个按键
Nut 工作模式分为 BootLoader 模式和应用模式,MODE键在不同工作模式下操作会进入不同的工作状态。Nut 上电后工作在应用模式下。
BootLoader模式下:
给Nut上电或者复位后,Nut 状态灯为浅蓝色,此时按下 MODE 键后 Nut 会进入到BootLoader模式下,继续长按 MODE 键直至状态灯出现以下颜色后释放,会进入对应的工作状态。
MODE键按下时间 | 状态灯颜色 | Nut工作状态 |
---|---|---|
0-3秒 | 无变化 | 无变化 |
3-7秒 | 红色 | 保留 |
7-10秒 | 绿色 | 恢复默认固件 |
10-13秒 | 蓝色 | 保留 |
13-20秒 | 浅蓝色 | 恢复出厂设置 |
20-30秒 | 熄灭 | 回到按键之前的状态 |
>=30秒 | 黄色 | 清除参数 |
应用模式下:
上电后 Nut 会进入应用模式,长按 MODE 键一定的时间直至状态灯变为相对应的颜色后释放,Nut 就会进入相应的工作状态,其关系如下所示:
MODE键按下时间 | 状态灯颜色 | Nut工作状态 |
---|---|---|
0-3秒 | 无变化 | 无变化 |
3-7秒 | 红色 | 进入或者退出配置模式 |
7-10秒 | 绿色 | 恢复默认固件 |
10-13秒 | 蓝色 | 保留 |
13-20秒 | 浅蓝色 | 恢复出厂设置 |
20-30秒 | 熄灭 | 回到按键之前的状态 |
>=30秒 | 黄色 | 清除参数 |
