器件型号：CC33XX-SOFTWARE 工具/软件：
您好：
我已成功集成 CC33XX Linux 驱动程序(v1.0.0.8) 我的 Yocto (Scarthgap) 基本映像。 BLE 扫描工作正常,我可以找到附近的设备使用bluetoothctl.
但是、当我尝试连接到 BLE 器件时、连接会暂时成功、但随后又成功 原因1稍后断开 。
步骤：
1- CD /usr/share/cc33xx
2 -./ ap_start.sh
3 -./ ble_enble.sh
4- hciconfig hci0 up
它们都不会失败,然后使用 bluetoothctl 我扫描可用的设备,然后尝试连接到其中一个。
日志 在 bluetoothctl 中：

是否知道为什么短时间后连接失败？
