Node.js 使用节点xbee发送数据包时出现校验和不匹配错误

配置为

协调器API的XBee Series 2正在尝试向配置为
路由器的XBee Series 2发送数据包。协调器连接到运行node.js的Mac OSX和

这会导致节点抛出错误：

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

使用路由器
侧的
上的Arduino串行监视器，我们可以看到协调器发送的数据实际上到达了路由器


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

解析协调器上接收到的帧时，似乎会抛出错误。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
——这是您的代码吗？有什么

如果您尝试来自
xbee api
的其他示例，它们是否有效

有些不相关，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。在XBee模块上堆积数据之前，从网络输入的数据被传送到主机

要启用硬件流控制，请将XBee模块上的
ATD6
和
ATD7
设置为
1
。这要求主机在发送到XBee之前检查来自XBee的
CTS
信号，并在准备接收来自XBee的字节时断言
RTS
信号。
出于某种奇怪的原因，我找不到
fs.js
。这不是我的密码。我已将协调器和路由器设置为115200 bps，但错误仍然存在。如何启用流控制？如果我继续重新启动同一个nodejs程序，在尝试几次之后，将不再出现校验和不匹配错误。但是，如果我再次重试，它将开始给出校验和不匹配错误，直到稍后重新启动。有什么想法吗？切换到Windows，它开始工作得很好。偶尔出现校验和不匹配错误，但仍不确定原因。它可能正在处理串行端口关闭时XBee模块上排队的帧。我的猜测是，有一种帧类型它并不熟悉，或者它正在处理部分帧，或者有帧错误。如果看不到解析后的帧，就很难确定了。我在回答中添加了关于启用流控制的说明。
