技术支持提问请严格按照以下格式提供对应信息，否则会影响回复时效，一定要描述清楚，以免一次回复无法解决问题
（提问前请先自查自己是否很仔细看过教程了，教程中的每句话都很重要，教程都是经过验证的，不会有问题的）
一、描述你遇到的问题
使用手机蓝牙串口助手跟开发板BLE进行通讯，发现有四个特征，但其中的UUID是固定不变的，在电脑使用串口发送数据，手机蓝牙串口也无法采集到我使用编译器搜索也没搜索到相关参数代码，目前只需要一个特征值且可以修改，是否有相关的修改或者调试教程文件，手机型号：华为P70
二、你具体做的所有步骤结果截图
三、当前开发板状态全景照片
四、开发板串口所有日志
请在此处粘贴串口日志
