bluetooth-lowenergy - com.polidea.rxandroidble2.exceptions.BleScanException：扫描失败，因为应用程序注册失败（代码 6）三星 Galaxy 8

问题描述

目前我正在一个涉及 ble 设备的应用程序中工作。我创建了一项服务并授予了蓝牙应用程序所需的所有权限并启用了蓝牙。当服务启动时，它会扫描 ble 设备并连接到它。但是在扫描时有时它会给我这个例外。

com.polidea.rxandroidble2.exceptions.BleScanException：扫描失败，因为应用程序注册失败（代码 6）

我正在使用这个库

任何形式的帮助将不胜感激。谢谢。
