編譯例如，mesh.c半自助旅遊旅行社

Question

如何解決這個錯誤：

undefined reference to button sensor 

在半自助旅遊旅行社使用Micaz微塵編譯example-mesh.c什麼時候？

這裏是我的代碼我在mote輸出窗口中運行模擬只有3條消息發送，其餘是「數據包超時」我怎麼能解決這個問題發送消息基於定時器的價值？

Answer 1

據我知道Micaz微塵不具有一個按鈕，因此參照button_sensor傳感器無效。

該示例旨在每次按下按鈕時發送消息，因此如果您希望此示例正常工作，則需要重寫示例以基於定時器值發送消息。

這就是我要寫的。但是，此節點依賴於需要接受消息的另一個節點！
