Re: wifi程序无法运行

IDF 更新过后需执行 git submodule update -f 更新一下 WiFi 库。

Re: Low speed on Wifi and character loss

Is the sdkconfig the same as the iperf example? Did you enable WiFi and BT software coexist?

Re: WiFi scanning

If you set country to USA, ESP32 will do active scan on channel 1~11. Fast scanning and all scanning methods are for connecting scan. If using fast scanning method, ESP32 will start to connect when it scans the first right AP(SSID matches). If using all scanning methods, ESP32 will start to connect ...

谢谢回复。我是pull的最新master分支才发现这个问题的。
现在我回退到v3.2 rc版本,这个问题就消失了
可以在 menuconfig 中增大 Component config > Wi-Fi > WiFi mgmt short buffer number 来避免这个问题,但最大是 32 个,如果还不行说明周围 station 太多了,超出了 softAP 的处理能力。

请问乐鑫的工程师可以提供一些建议吗?
现在是 50ms 进入 modem sleep,已经很快了,再快会影响 WiFi 性能。

Re: ESP32的smartconfig

用的开发版尝试smartconfig,功能使用正常,但是只要重启后又要设置一遍 怎么才能记住配置? 1. 使能 menuconfig -> Component config -> Wi-Fi -> WiFi NVS flash。 2. app_main() 函数一开始调用 nvs_flash_init() 初始化 NVS。 3. 在 esp_wifi_init() 之后调用 esp_wifi_set_storage(WIFI_STORAGE_FLASH)。 4. 在 esp_wifi_set_mode(WIFI_MODE_STA) 之后调用 esp_wifi_get_config() 获取存...

Re: Correct setting of ESP-Now

In my project I use protocol ESP-Now as a way of communication between ESP32 boards. I have some questions about setting ESP-Now. The first ESP board only reads the data from sensors and sends it through ESP-Now. The second board receives ESP-Now data but in the same time is also connected to Wi-Fi...

基于esp_idf/wifi/simple_wifi这个示例,调用wifi_init_sta函数测试的是STA模式,第一次连接成功,接着马上重启,就会出现连接失败,再重启一次,又会连接成功,再重启又会连接失败,如此规律的重复
请问你使用的 IDF 是哪个版本的?请使用最新的 master 分支测试一下有没有问题。
已经是使用的最新版本的了。就是在出现这个问题的时候,我就git pull+git submodule update过了
请问你使用的路由器的牌子和型号是什么?
