Re: ESP32-WROOM-32 Work As AP

By submitting an error to espressif officially, I received the following reply: I found out that this was because the iPhone did not send a deauth packet when the wifi was turned off, causing 32 unable to detect that the phone was disconnected. When ESP32 is used as Ap, if the STA does not receive d...

Re: ESP32-WROOM-32 做AP的问题

通过向乐鑫提交BUG,得到如下反馈:
经测试发现出现这种情况是因为iphone手机在关掉wifi的时候没有发送deauth包,导致32检测不到手机断开。而ESP32作为Ap的时候,如果超过5min没有收到STA的数据,则会主动踢出STA。

ESP32-WROOM-32 Work As AP

When using ESP32 as a hotspot, if you connect the module with an Android phone or a computer, the module can detect that the Android phone/computer is disconnected when disconnected. But with the Apple phone connection module, when disconnected, the module seems to often fail to detect that the Appl...

ESP32-WROOM-32 做AP的问题

用ESP32做热点时,如果用安卓手机或者电脑连接模块,在断开连接时,模块能检测到安卓手机/电脑断开了。但是用苹果手机连接模块,在断开时,模块好像经常检测不到苹果手机断开了。是通过SYSTEM_EVENT_AP_STADISCONNECTED事件打印调试信息来观察的。
这样导致的问题是,当设置只运行1个STA连接模块时,即使是苹果手机已经关闭了WIFI,其他手机也无法连接模块。
有人遇到过跟我一样的问题吗?

ESP32-WROOM-32 TCP数据发送问题

在使用ESP32的WIFI发送TCP数据时(模块做AP,TCP-Server),用send函数发送数据时,经常出现进到send后就出不来了的情况,唯一的解救办法就是断开WIFI连接,send才会返回,此时串口会打印“ampdu: ignore deleting tx BA0”,有谁知道是什么原因导致的吗?

ESP32-WROOM-32 串口2的问题

我想使用ESP32-WROOM-32的串口2,使用如下初始化代码(在ble_spp_server.c例程中将UART_NUM0 -> UART_NUM2),发现串口2既收不到数据,也发不出来数据,请问使用串口2有什么要注意的吗,还是ESP32-WROOM-32串口2不能用? static void spp_uart_init(void) { uart_config_t uart_config = { .baud_rate = 115200, .data_bits = UART_DATA_8_BITS, .parity = UART_PARITY_DISABLE, .stop_bits = UA...
