Feature description

现象：
我已经完全通过setup.ps1的环境安装:
默认拉取的是 --preview ESP32C5 V5.5.0版本idf

该环境已经拉取完成，并且作为系统环境在VSCODE下的IDF_PATH或作为临时终端环境；
并且已经成功构建。
因为上述流程变更了.a库、所以需要验证IDF库的变更是否会影响ESP直接作为MCU使用WIFI功能
对下述两个实例进行测试：
运行 examples/wifi/getting_started/softAP 实例无法让外部设备扫描到
examples/wifi/getting_started/station 实例，出现如下段错误：

Use cases

    我们项目的目标是希望能够在主机host进入休眠或者关机时，能够让ESP32C5作为独立的MCU去使用相关功能；因此，需要确认在使用hosted-ng的框架下，是否还支持独立的AP或者STA功能。
   在这个大量xxx.a文件变更的情况下 eg:libnet80211文件，默认SDK示例无法正常使用，请帮我确认一下上述使用场景是否可以实现。

No changes should be done or required manually.

@kapilkedawat , Can you please check the crash?

@2024HYJ , can you please state the firmware version used?
Host power saving is allowed. But your linux should support this function. please check the https://github.com/espressif/esp-hosted/blob/master/esp_hosted_ng/docs/host_sleep.md for details.

您好！
当前版本与运行条件如下：

Project release version

sdk v5.5.0(由setup.ps1拉取的子模块SDK) ; esp_host-ng fireware:1.0.5.0.3

System architecture

Intel/AMD 64-bit (modern PC, older Mac)

Operating system

Windows

Operating system version

Window 11

默认安装使用的是v5.5.1版本SDK，hosted-ng环境使用的是./setup.ps1安装之后的ESP-IDF(v5.5.0 --preview版本)
上述测试过程中，在v5.5.1版本的默认SDK是可以正常使用WIFI功能的；但是hosted-ng版本环境下，使用示例AP/STA无法正常工作。
我们测试的重点是并非是主机能否进入休眠而是希望能否实现主机休眠(或关机)的时候，ESP32C5能否自己独立的使用WIFI功能。

另外在这个框架下，是否支持蓝牙ble？尤其是主机不工作的情况下(休眠或关机)，ESP32C5能够独立BLE工作?

[mantriyogesh]

During the above test, the WIFI function can be used normally with the default SDK of version v5.5.1; however, in the hosted-ng version environment, it cannot work properly using the example AP/STA.

Can you please add logs and let us know exact issues that you face?

The focus of our testing is not whether the host can enter hibernation but whether the ESP32C5 can use the WIFI function independently when we hope to achieve hibernation (or shutdown) of the host.

Yes I had pointed out the host sleep documentation in ealier comment. https://github.com/espressif/esp-hosted/blob/master/esp_hosted_ng/docs/host_sleep.md. Host Sleep is supported. Host power off is not supported directly from the repo. but it should also just work, without issues. in fact it would be simpler than even host sleep. Although, please note that kernel module need to be inserted once host resets, to make wlan0 up on boot.

There are many Linux standard ways to auto insert the kernel module. You can choose what your distribution allows.

Also in this framework, is Bluetooth ble supported? Especially if the host is not working (sleep or shutdown), is the ESP32C5 able to work independently with BLE?

Bluetooth is supported out-of-the-box. ESP32-C5 is bluetooth controller and we use BlueZ bluetooth stack on the the Linux.
The bluetooth messages (and Wi-Fi, cfg80211 backend control messages) are multiplexed using ESP-Hosted header over the communication bus like SDIO/SPI. Running BLE using ESP32-C5 should be effortless, once you get Wi-Fi ESP-Hosted working on Linux.

对于日志，直接使用了默认示例代码(上文有写路径)，现在我将log_level 变更为verbose等级输出给到您(日志：log_test.txt)：
日志包含默认示例代码中AP与STA的运行流程：

也许我之前的描述不太清晰？
我将补充说明我们项目的核心需求，避免之前的理解偏差：
项目最终目标：主机进入休眠后完全不工作（无需主机参与任何运算或通信）；
关键要求：在 hosted-ng 环境 下，主机休眠时 ESP32-C5 需 独立完成以下功能：
正常启用 WiFi 功能（无需依赖主机）—— 项目中主要需要WiFi扫描的功能；
主机不休眠时，使用场景将与当前hosted_ng常规场景一致。
关键点：在hosted-ng环境中，能否做到esp32c5不依赖主机，独立实现WiFi功能；能够成为一个独立的MCU去使用。

Bluetooth is supported out-of-the-box. ESP32-C5 is bluetooth controller and we use BlueZ bluetooth stack on the the Linux.
The bluetooth messages (and Wi-Fi, cfg80211 backend control messages) are multiplexed using ESP-Hosted header over the communication bus like SDIO/SPI. Running BLE using ESP32-C5 should be effortless, once you get Wi-Fi ESP-Hosted working on Linux.

蓝牙对我们项目来说非常重要！我们期望在项目中的最终目标：
主机休眠与不休眠，都不影响蓝牙在esp32c5的从机端运行；它能够正常接收 BLE 数据，并在 ESP32-C5 本地完成数据处理（无需将 BLE 数据转发给主机，也无需主机协助处理）；
当前问题：在hosted-ng版本环境中，menuconfig的依赖关系是否会导致蓝牙异常？menuconfig中蓝牙使能选项，中配置NIMBLE-Noly_ble作为host将导致无法项目构建。是否可以在这hosted-ng框架下完全不在主机控制的情况下使用蓝牙ble，ble仅在esp32c5侧完全实现；

当前问题进度：使用 hosted-ng 版本环境运行 AP/STA 示例时，WiFi 已无法正常工作，需先排查该环境下 ESP32-C5 独立运行 WiFi 的问题，后续再验证 BLE 独立工作能力。

[mantriyogesh]

The ultimate project goal: the host becomes completely inactive after going dormant (no need for the host to participate in any operations or communications);
Key requirements: in the hosted-ng environment, ESP32-C5 does the following independently while the host is dormant:
Enable WiFi functionality normally (no need to rely on the host) —— the main feature in the project that requires WiFi scanning;
When the host is not dormant, the usage scenario will coincide with the current hosted_ng regular scenario.
Key points: In the hosted-ng environment, can esp32c5 not rely on the host and independently implement WiFi functions; can it be used as an independent MCU.

This is already supported as part of host sleep feature.

Bluetooth is very important for our project! The ultimate goal we expect in a project:
Whether the host is dormant or not does not affect Bluetooth’s operation on the slave side of esp32c5; it is able to receive BLE data normally and complete data processing locally in ESP32-C5 (no need to forward BLE data to the host, and no host assistance in processing);

In esp-hosted-ng , the bluetooth is by default used in split or standard HCI mode.
What it means, the controller stack runs over ESP32-C5 and Bluetooth host stack (BlueZ) runs over Linux.
But this is different than what you need. So you can avoid using Bluetooth from host side altogether.

In this case, we might have to verify only Wi-Fi mode works with esp-hosted-ng.

But essentially, Bluetooth you can use on your own as standard esp-idf example. meaning, instead of running oin standard HCI mode or Split mode, you need to run the Bluetooth Host (NimBLE) and BLE controller both on the ESP32-C5. In this case, Linux would not know or handle any BLE packets.

Current problem progress: When using the hosted-ng version environment to run the AP/STA example, WiFi no longer works properly.

We expect this to works just fine, without any changes. Please share as much as possible which would let us see the issue and the logs associated to understand the root cause of this issue.

Please note, Wi-Fi as station mode is supported. Wi-Fi as AP mode is supported. Wi-Fi as both, Station + AP mode is not currently supported by ESP-Hosted-NG. You can use ESP-Hosted-FG for this, if it suits.

If you are running station only mode or ap only mode and you see any issues, please help with detailed logs:

1. ESP full textual log
2. Linux wpa_supplicant debug logs (station only mode)
3. Linux hostapd debug logs (ap only mode)
4. dmesg from system boot up

You need to first troubleshoot the problem of ESP32-C5 running WiFi independently in this environment, and then verify the independent working ability of BLE.

We will focus first on Wi-Fi. getting worked.

Configuring NIMBLE-Noly_ble as host in the Bluetooth enable option in menuconfig will result in the inability to build the project. Is it possible to use Bluetooth ble without being controlled by the host at all under this hosted-ng framework, ble is fully implemented only on the esp32c5 side;

As stated ealier, let us take step by step, first let us check if Wi-Fi works as expected. ESP-Hosted-NG may need to test or change to avoid using Bluetooth by default. Disabling Bluetooth altogether is supported on ESP-Hosted-FG. But will park bluetooth questions for now, please confirm Wi-Fi working first. then we will move to bluetooth problem. Looks good?

[mantriyogesh]

Basically, I would suggest to disable bluetooth altogther at c5 from menuconfig, and first only get wifi working. once this is shown to work fine, we will continue ahead.

Hey @2024HYJ I think you are trying to run [station_example](https://github.com/espressif/esp-idf/tree/master/examples/wifi/getting_started/station) from esp-idf with esp_hosted_ng development env. The Esp_hosted_ng development env is not supposed to be used with esp-idf examples, hence you are facing the crash. Can you explain your use case so that we can guide you further?

[2024HYJ]

嘿，我觉得你是在尝试用 esp_hosted_ng 开发环境从 esp-idf 运行。Esp_hosted_ng开发环境本不应该用在 esp-idf 示例中，所以你遇到了崩溃。你能解释一下你的使用场景吗？这样我们才能进一步指导你？[station_example](https://github.com/espressif/esp-idf/tree/master/examples/wifi/getting_started/station)

@Shreyas0-7
我们最终预期的使用场景:
esp32c5将与一个linux设备(主机)互联，我们期望在主机正常工作的情况下，能够使esp32c5做网卡使用，实现esp32c5使用AP或者STA模式进行视频资源的传输(但对于esp32c5来说不局限于网卡功能，eg:从机需要自由实现蓝牙ble数据传输)；主机在进入休眠或者关机状态的时候，能够实现esp32c5成为一个独立的MCU，释放掉SDIO相关资源，自己独立实现WIFI功能(主要做扫描使用)、同时蓝牙ble也不会受到影响而关闭，仍然能独立运行。
在这个环境框架下，我们要求esp32c5能够独立实现蓝牙ble功能(蓝牙控制器与蓝牙主机栈均运行在esp32c5上)，不对(host)主机做出任何数据处理与转发；主机是否处于休眠状态不会影响蓝牙在 esp32c5 从属端的运行;它能够正常接收BLE数据，并在ESP32-C5中本地完成数据处理（无需将BLE数据转发给主机，也无需主机协助处理）;

当前为什么会做出使用esp-hosted-ng的环境去esp-idf示例(/examples/wifi/getting_started/station ;  /examples/wifi/getting_started/softap)中运行？是因为我们需要在主机休眠的时候，确认esp32c5能否在hosted-ng的环境中自己独立实现WIFI功能。因为我们观察到，默认ESP-IDF固件库的部分.a库在环境切换时，发生了改变 (eg:libnet80211.a) ；所以做出了这个测试，并确认当前无法在这个框架下自己实现WiFi功能，因此提出了这个问题，需要获取结论；
而蓝牙ble对于我们来说，相当重要；上述环境中，蓝牙ble是我们的核心业务，因此急需确认这个需求是否能够在这个环境中实现(蓝牙ble不受到影响)？


另外:
1、我们观察到主机唤醒的时候，会去复位esp32c5，这个复位是否是一定需要的？因为，我们的所有电源均连接在esp32c5上(包括主机)，这一点至关重要！我们期望该阶段不会对esp32c5做出复位操作。这个复位是否能够避免或者我们自己实现复位想要的结果？从而避免esp32c5做出复位。
