    FR8018主从连接异常
    两个从机程序相同，由主机扫描到后进行连接，一个连接正常可以通信，另一个异常
    正常从机打印：

    你这个是一个主机连接两个从机？，如果是要连接两个从机的话，需要修改连接个数具体参考：【有道云笔记】FR801xH ble空间设置

    没有用，还是上面那个效果，目前测试1主4从，仅有1从机表现异常，也尝试仅1主1从连接这个异常从机，仍无法收到主机消息，主机可以收到从机消息；使用手机app连接时，这四个从机表现均正常。

    你的从机的代码不是同一份吗，为什么有的从机能传输有的又不能，传输的连接号对应上了吗

    是同一份程序，从打印情况看是连接上了，但是就是不能通信，另外尝试无法通信从机刷主机程序，连接别的从机，也显示连接上了，但是这个主机无法通信正常从机，相当于这颗芯片的蓝牙仅能做从机被手机app连接表现正常。
