Question

我无法使用我的Arduino Uno工作的蓝牙模块。我已按照本网站的说明操作： http://www.instructables.com/id/Arduino-AND-Bluetooth-HC-05-Connecting-easily/?ALLSTEPS

所以在我的蓝牙设置上它说COM7 Incoming所以我把它放在Putty和COM8中用于传出所以我把它放在arduino IDE中。我收到这些错误

Answer 1

你得到的是“程序员没有响应”消息，因为其他一些进程正在使用COM8端口。如果某个其他程序（如串行终端）正在使用该端口，则无法通过该端口对Arduino进行编程，因此请退出程序，对Arduino进行编程，然后再次打开该程序。

Answer 2

首先，您是否尝试通过蓝牙下载程序，因为如果您不是，那么它就不会起作用。如果您尝试使用USB电缆上传程序，请确保您在正确的COM端口（而不是蓝牙COM端口）。上传程序时，请保持电源和接地连接，使其仍然处于激活状态，但您需要断开rx和tx连接（两个数字端口连接）。这是蓝牙模块的常见问题，因为出于某种原因，当连接rx和tx时，它会干扰程序上传的能力。

Answer 3

此问题或类似的问题“ avrdude：stk500_recv（）：程序员没有响应”很容易解决。

如果Arduino已通过HC-06蓝牙模块连接到面包板，则会发生这些问题。

首先，将Arduino从电源上拔下，然后断开Arduino与面包板之间的连接。接通Arduino的电源并检查串行通讯。端口是正确的。现在，将草图上传到Arduino将会没有问题。最后，拔下Arduino的电源，然后将Arduino重新连接到面包板上。

将蓝牙模块连接到Arduino时，该模块会阻止Arduino的串行端口连接到USB来上传草图。
