使用ROC-3328-PC低功耗蓝牙时遇到问题。
使用开发板：ROC-3328-PC使用固件：ROC-RK3328-PC-UBUNTU18.04-GPT-20200303-1705.img
问题描述：使用了Node.js下的bleno库，创建了一个蓝牙外围设备，在手机上使用BLE调试工具可以查询到这个外围设备，但是进行连接的时候，连接不上。bluetooth的服务的日志显示Can't store services for private addressed device。使用的bluez的版本为5.48
firefly@firefly:~$ sudo journalctl --unit=bluetooth

我也碰到同样的问题，但是可以连接上，但是找不到外围设备的Characteristic值，所以无法传输数据
