扫描、查找、连接并发送数据到 AC6328A 上的 SPP 设备 : SPP_BUFF NULL!!! #196

Open 0x0fe opened 1 year ago

0x0fe commented 1 year ago

我们的产品必须连接到第三方蓝牙 SPP 设备(ODBII 适配器),它将向其发送命令和接收数据。

由于第三方设备由最终用户提供,因此连接必须仅通过名称来完成。

在与 SDK 进行了数小时的斗争之后,仍然无法完成这个非常简单的任务。 显然,SDK 没有提供通过名称扫描和查找 SPP 设备然后连接到它的机制,因此我们可以使用正常的 SPP 功能来发送和接收数据。

我能找到的最好的方法是在将应用程序设置设置为 EDR 并使用 SPP 配置文件禁用 BLE 时使用 edr_emitter。 这样我至少可以看到设备,但仍然无法连接到它,也无法使用 SPP 功能。 我也没有看到 SPP 回调被触发,尽管它可以找到和设备并且似乎已连接。

我们能否获得一个简化的示例或存在此类示例的链接以实现以下目标:
