感謝使用 Node.js Taiwan AMA，以下附上簡單提問範例供參考，請把內容改成你自己遇到的問題
目的
在每次接收到從各個xbee收到資料時能回應"ack"供判斷
使用的工具
<<我在 Pi3 - Raspbian GNU/Linux 下使用 npm 安裝 node.js 6.9.5 >>
操作流程
<<我下了 xxx 指令，輸入了下面的程式碼，>>
遇到的問題
參考了網路上範例使用xbee-api 目前想讓他每XX時間送出時間的資訊 (可能是以小時為單位) 在每次接收到從各個xbee收到資料時能回應"ack"供判斷 但必須知道來源是哪顆xbee所以用變數recadd紀錄下來 像這樣的變數如何傳到下方傳送的地方做使用呢
嘗試過的解法
試過把傳送ack整段塞進讀取封包的地方但無反應
