无法从STM32 B-U585I-IOT02A检测到蓝牙

Question

我正在使用来自 STM32CubeIDE 1.7.0 的 BLE_AT_CLIENT 示例，但在 ST BLE SENSOR 应用程序或我的 computer/smartphone 正常蓝牙扫描中未检测到任何内容。我有 2 个 B-U585I-IOT02A，并且都在 teraterm 上给出了完全相同的错误消息。 error message on teraterm

这里还有来自控制台的日志。

Answer 1

我刚想出如何解决这个问题，首先我必须re-flash将STM32WB5MMG固件升级到最新版本，然后从https://github.com/STMicroelectronics/STM32CubeWB

刷入BLE_AT_Server_reference.hex

不要使用二进制库中的 BLE_AT_Server.hex，它会禁用 swd 连接，如果你碰巧这样做并且无法再连接到开发板，只需将 stm32programmer 模式更改为 under reset然后按下蓝牙模块的复位按钮并松开，它会让你连接到蓝牙模块并清除程序。

之后我遇到了另一个问题，有时程序会挂在“TX：AT”，为了解决这个问题我必须重置蓝牙模块然后重置主板，或者简单地重置主板和re-plug USB 数据线。
