Movesense BIG_MEM传感器移动唤醒流程异常问题咨询

问题表现 #

• 摇晃传感器超过2秒后，传感器唤醒并开始闪烁LED
• 5秒后设备关机随即重启，再次闪烁LED，5秒后才进入关机模式
• 无Movesense programmer，无法查看硬件日志

硬件规格 #

• 传感器型号：Movesense "BIG_MEM"
• HWCONFIG: SS2_NAND
• 数据内存：128 MB FLASH
• 1-Wire master: YES
• Movesense-device-lib版本：未提供

代码说明 #

基于Movesense官方示例代码仅做少量修改：

• 唤醒至进入关机模式的时间间隔：#define AVAILABILITY_TIME 5000
• 广播模式下LED闪烁周期：#define LED_BLINKING_PERIOD 1000

预期行为 #

摇晃Movesense传感器后立即唤醒，5秒后进入完全关机模式。
