[参考译文] SK-AM62P-LP：SK-AM62P-LP 上通过蓝牙播放音频问题

尊敬的 Veerapandiyan：

您能否分享您尝试验证方案的渠道？ 您是否使用 avdtpsrc 从 A2DP 器件接收数据？

根据您的查询、我可以正常播放（存储在 EVM 到耳机插孔上的文件）。

此致、

Suren

您好、Suren、

我从您的查询中了解到的是正常播放（存储在 EVM 到耳机插孔上的文件）工作正常。

理解是正确的。

您能否共享您尝试验证方案的管道？ 您是否使用 avdtpsrc 从 A2DP 设备接收数据？

我在文件下分享了一些日志

我需要 2AE M.2 模块的补丁文件。 请共享补丁文件、我将检查我的配置是否正确。

您好、  

我正在将您的查询发送给连接团队、以便更好地支持您使用 M2 模块和补丁。 期待尽快作出响应。

尊敬的 Veerapandiyan：

您能否分享 EAR00388 用户指南中作为推荐蓝牙模块的位置？

我们已 按照以下链接中提供的说明验证了与 M2-CC3351 电路板的连接：

https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/latest/exports/docs/linux/How_to_Guides/Target/How_To_Enable_M2CC3301_in_linux.html

您好、Suren、

您能分享关于 EAR00388 作为推荐蓝牙模块的用户指南中提到的位置吗？

您提到了 AM62x Spruj 用户指南链接： https://www.ti.com/lit/ug/spruj40d/spruj40d.pdf?ts = 1758714418765 

第 33 页,这就是为什么我提到你的建议。 下面随附了屏幕截图

、  

我正在将您的查询路由到连接团队、以便更好地支持您使用 M2 模块和补丁。 期待尽快回复。

好的。 我正在等待。

此致、
Veerapandiyan 五.

尊敬的 Veerapandiyan：

您是否联系过村田社区论坛或嵌入式艺术家的脚本?

我们仅使用我们的 EVM 验证了 CC3351、可为您解答与 M2-CC3351 相关的任何问题。

此致、

Suren

你好 Suren、我

为什么提到此模块 AM62x 用户指南？

• 蓝牙模块：  EAR00388（根据 AM62x 用户指南 M.2 模块中的建议）

[引述 userid=“533957" url="“ url="~“~/support/processors-group/processors/f/processors-forum/1568911/sk-am62p-lp-audio-playback-issue-via-bluetooth-on-sk-am62px-lp/6047579

您是否联系过村田社区论坛或嵌入式艺术家的脚本?

[/报价]

下一步、我们将做什么？ 请告诉我们？

您好、Suren、  

我正在等待你的答复。

此致、
Veerapandiyan 五.

尊敬的 Veerapandiyan：

我已联系团队、了解他们如何使用 EAR00388 验证它。 请等待几天后再回来。

此致、

Suren

尊敬的 Veerapandiyan：

e2e.ti.com/.../k3_2D00_am625_2D00_sk_2D00_8.6.dts

请检查随附的 DTS 文件以及支持 EAR00388 WLAN 模块的配置。 我们的团队使用 SDK 8.6 进行了验证。 DT 节点可能与最新的 SDK 存在一些兼容问题、但配置属性将保持不变。

希望这有所帮助

此致、

Suren

尊敬的 Veerapandiyan：

由于我们的团队已经在 8.6 SDK 上验证了它、您是否能够在 8.6 SDK 上进行验证、并在我重新与 IP 团队核实时查看它是否按预期工作。  

此外、Murata 团队是否对您的查询做出了回复？

此致、

Suren

您好、Suren、

英飞凌团队 建议升级 BlueZ5、 但我尝试了多种方法,版本仍然没有更新。 它只保持在 5.72。
请告知如何将其更新到最新版本。

此致、
维拉潘迪扬五世

尊敬的 Veerapandiyan：  

由于 Bluez5 不是 TI 软件、您可能必须联系 Infineon 或 BT 堆栈供应商以获得支持。

您是否可以下载 BlueZ5 的软件包（不是 5.72）并使用 opkg install bluez.ipk（如果 bluez.ipk 是您要安装的版本）进行安装、然后试用。

此致、

Suren

您好、Suren、

我已将 Bluez 更新为版本 5.83、但仍存在相同的错误。 我附上了屏幕截图和 log.txt 文件以供您参考。

如果您需要任何其他详细信息或特定信息、请告知我。
