器件型号：CC1352R 您好！
我正在尝试在 SDK 4.10中重置 BLE 堆栈。 SP OAD 片外示例项目。 遗憾的是、它不起作用。
我要做的是：
在特定情况下、我调用 HCI_ResetCmd。 它将返回成功。
然后、我等待 HCI_RESET 事件、该事件恰好在 HCI_ResetCmd 调用之后出现。
在这里、我调用 GAP_DeviceInit、它返回 bleIncorrectMode。
我从 这里 和 这里获得了该解决方案。
根据我的理解、当 HCI_ResetCmd 之前未调用时、GAP_DeviceInit 返回 bleIncorrectMode。
这里的问题是什么？
最有趣的代码片段：
