【鸿湖万联启鸿开发板试用体验】蓝牙使用的问题

开发板支持蓝牙连接开发板，并用蓝牙进行下载程序。

在连接设备页面下，选择蓝牙，可以看到列表下已经有一个CH9141BLE2U的设备了，直接可以进行连接。

连接成功后，会显示已连接

下载程序时，可以选择用蓝牙进行下载。

蓝牙下载程序是比较慢的，而且下载时，网页会全部白一下并转几个圈圈。

当使用蓝牙下载程序、连接开发板时，不要再在代码里操作蓝牙外设，否则会导致开发板的蓝牙连接断开的问题。

如果想用电脑连接蓝牙传输数据，可能就会有一些问题了。

断开蓝牙，把网页刷新一下，重新插拔一下开发板，用USB连接上电脑。

在电脑上找到蓝牙后，点连接，会让输入PIN码，而这个码目前不知道。

手机连接也是一样的。

如下，手机与电脑上通过蓝牙搜索来连接开发板的蓝牙都是会配对失败的。

但是，用BleUart工具连接，却可以连接上，也不需要输入PIN码。

连接上后，蓝牙的状态灯也不会闪烁了。

在软件上，进行数据发送，每发送一次，开发板上的蓝牙状态灯会闪一次。

但却收不到蓝牙的数据。

开发板串口的输出如下，目前不知道是哪里的问题，技术人员也是非常的繁忙，还没有回复。
