配置为 a 的 XBee 系列 2Coordinator API正在尝试向配置为 a 的 XBee 系列 2 发送数据包Router AT。Coordinator 连接到运行 node.js 和xbee-apilibrary的 Mac OSX 。

var frame_obj = {
    type: 0x10,
    ud: 0x01,
    destination64: "0013a20040b19213",
    data: "1"
}

serialport.write(xbeeAPI.buildFrame(frame_obj))

这会导致 Node 抛出错误：

/Users/me/Dropbox/Projects/test-node/node_modules/xbee-api/lib/xbee-api.js:173
        throw new Error("Checksum Mismatch", S);
              ^

使用AT Router侧面的 Arduino 的 Serial Monitor，我们可以看到 Coordinator 发送的数据实际上到达了 Router。

问题：为什么会出现校验和错误？我们怎样才能解决这个问题？

解析在协调器上接收到的帧时似乎引发了错误。如果是这种情况，您可以转储接收到的帧吗？

堆栈跟踪指向fs.js:454:17——那是你的代码吗？什么东西在那里？

如果您尝试来自 的其他样本xbee-api，它们是否有效？

有点不相关，但我建议以 115200 bps 的速度运行协调器，并确保在串行库和 XBee 模块中都启用了流控制。这避免了缓冲区溢出的问题。来自网络的数据在堆积到 XBee 模块之前被传送到主机。

要启用硬件流控制，请将XBee 模块上的ATD6和设置为. 这要求主机在发送到 XBee 之前检查来自 XBee 的信号，并在准备好从 XBee 接收字节时断言信号。ATD71CTSRTS
