[参考译文] CC2652P：BLE 连接错误 CC2652P

尊敬的 Sebastian：

我建议您逐步解决问题、首先确认器件是否能够接收和发送数据(您可以使用 SmartRF Studio 执行此操作)。

确认该条件后、您可以考虑转到下一步并执行 simple_peripheral 等软件示例。

我希望这将有所帮助、

此致、

您好，Clement，

感谢您的答复。 如前所述、我们验证了 TX 和 Rx 是否可以与 SmartRF Studio 一起工作。

但它仍会停止广播。 我们加载示例代码 simple_peripheral、有时我们有 ICall 中止、有时和 Error_spin、如下所示：

我们已经看到了这篇文章,并尝试了相同的事情,但它不能为我们工作: https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1191771/cc2652p7-cc2652p7/4498493?tisearch=e2e-sitesearch&keymatch=cc2652p7#4498493

此致、

Sebastian

尊敬的 Clement：

感谢您的答复。

实际上、我们遵循了德州仪器应用手册的硬件设计。

一切运行正常、计时器、UART、驱动程序、传感器控制器、 等等... 它只是 ICall 中具有更高优先级的 BLE 任务。 即使没有修改的 cc1352p7_4示例代码也只广播一次、然后我们将其丢失。

我可以向您发送示意图、您可能看到了什么问题吗？

谢谢！

此致、

Sebastian

您好、Matt、Clement、感谢您的答复。

我正在与 Sebastian 合作开发 CC2652P。

我已经检查了32.768kHz 石英和48MHz 石英的焊接、没有问题。 我还用示波器检查了它们是否正常振荡、一切似乎都正常。 我不确定是否存在硬件问题...

我还使用 SmartRF Studio 进一步进行研究、即在数据包 TX 模式下连接 CC2652R、在数据包 RX 模式下连接我们的自定义电路板(带有 CC2652P7_4)。

所有数据包均已正确接收。

我在数据包 TX 模式下执行同样的操作、一切都正常。

我认为这是软件问题、或者可能是配置问题。

该器件似乎正常广播、我可以在 BLE Scanner 应用上看到它、但如果我尝试连接、我将卡在 ICALL 环路中。

我在 SysMin 输出中记录了 BLE 堆栈 MSG：

很遗憾听到。 有时我发现有一个电容器悬挂在焊盘上、或者在连接不住时、使用错误的天线设置。 我把你搞砸了—也许你想分享一些代码吗？ 我对 CC2652P 的故障模式也拥有既得利益！
