用ESP32-S3开发的产品，经常遇到WIFI连接路由器失败的情况，为什么？

问答对人有帮助，内容完整，我也想知道答案 0 环境是：ESP-IDF v4.4.3 使用ESP32-S3开发的产品，设备开机连接路由器正常，然后断电关机，重新开机连接，这样反复测试，经常会遇到连不到路由器的情况（将设备贴近路由器也是一样的效果，不是信号问题）。连接异常时，将SYSTEM_EVENT_STA_DISCONNECTED的异常打印出来 case SYSTEM_EVENT_STA_DISCONNECTED: ESP_LOGI(WIFINET, "rn--------SYSTEM_EVENT_STA_DISCONNECTED ---------"); wifi_event_sta_disconnected_t sta_disconnect_evt = (wifi_event_sta_disconnected_t)event; ESP_LOGI(WIFINET, "wifi disconnect reason:%d", sta_disconnect_evt->reason); GeSHi © Codebox Plus Extension 打印的是：WIFINET: wifi disconnect reason:225 产品处于等待量产的阶段，麻烦厂家技术人员指导一下是什么问题完整的日志如下： ESPESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0xf (BROWNOUT_RST),boot:ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0xf (BROWNOUT_RST),boot:0x1f (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:1 load:0x3fce3808,len:0x17c0 load:0x403c9700,len:0xe64 load:0x403cc700,len:0x2fe4 entry 0x403c9980 [0;32mI (25) boot: ESP-IDF v4.4.3-dirty 2nd stage bootloader[0m [0;32mI (25) boot: compile time 16:57:51[0m [0;32mI (25) boot: chip revision: 0[0m [0;32mI (27) qio_mode: Enabling default flash chip QIO[0m [0;32mI (33) boot.esp32s3: Boot SPI Speed : 80MHz[0m [0;32mI (37) boot.esp32s3: SPI Mode : QIO[0m [0;32mI (42) boot.esp32s3: SPI Flash Size : 4MB[0m [0;32mI (47) boot: Enabling RNG early entropy source...[0m [0;32mI (52) boot: Partition Table:[0m [0;32mI (56) boot: ## Label Usage Type ST Offset Length[0m [0;32mI (63) boot: 0 nvs WiFi data 01 02 00009000 00004000[0m [0;32mI (71) boot: 1 otadata OTA data 01 00 0000d000 00002000[0m [0;32mI (78) boot: 2 phy_init RF data 01 01 0000f000 00001000[0m [0;32mI (86) boot: 3 ota_0 OTA app 00 10 00010000 001f0000[0m [0;32mI (93) boot: 4 ota_1 OTA app 00 11 00200000 001f0000[0m [0;32mI (100) boot: End of partition table[0m [0;32mI (105) esp_image: segment 0: paddr=00010020 vaddr=3c0c0020 size=5d728h (382760) map[0m [0;32mI (171) esp_image: segment 1: paddr=0006d750 vaddr=3fc99680 size=028c8h ( 10440) load[0m [0;32mI (173) esp_image: segment 2: paddr=00070020 vaddr=42000020 size=bcfe8h (774120) map[0m [0;32mI (294) esp_image: segment 3: paddr=0012d010 vaddr=3fc9bf48 size=02060h ( 8288) load[0m [0;32mI (296) esp_image: segment 4: paddr=0012f078 vaddr=40374000 size=15678h ( 87672) load[0m [0;32mI (317) esp_image: segment 5: paddr=001446f8 vaddr=50000000 size=00010h ( 16) load[0m [0;32mI (326) boot: Loaded app from partition at offset 0x10000[0m [0;32mI (326) boot: Disabling RNG early entropy source...[0m [0;32mI (337) cpu_start: Pro cpu up.[0m [0;32mI (338) cpu_start: Starting app cpu, entry point is 0x40375460[0m [0;32mI (0) cpu_start: App cpu up.[0m [0;32mI (351) cpu_start: Pro cpu start user code[0m [0;32mI (352) cpu_start: cpu freq: 240000000[0m [0;32mI (352) cpu_start: Application information:[0m [0;32mI (354) cpu_start: Project name: esp32s3wyb[0m [0;32mI (360) cpu_start: App version: 1[0m [0;32mI (364) cpu_start: Compile time: Dec 17 2022 17:00:06[0m [0;32mI (370) cpu_start: ELF file SHA256: 4262afd5beedd0b6...[0m [0;32mI (376) cpu_start: ESP-IDF: v4.4.3-dirty[0m [0;32mI (381) heap_init: Initializing.

答案对人有帮助，有参考价值 0 根据您提供的信息，您的ESP32-S3设备在使用ESP-IDF v4.4.3开发时，经常遇到WIFI连接路由器失败的情况。以下是一些可能的原因和解决方案： 1. 固件问题：您使用的ESP-IDF版本可能存在一些已知或未知的bug。尝试升级到最新版本的ESP-IDF，看看问题是否得到解决。 2. 电源问题：设备在重新开机时，电源供应可能不稳定，导致WIFI模块无法正常工作。检查电源电路，确保电源供应稳定。 3. WIFI模块硬件问题：WIFI模块可能存在硬件故障。尝试更换WIFI模块，看看问题是否得到解决。 4. 信道冲突：您的设备可能与其他设备使用相同的信道，导致信道冲突。尝试更改路由器的信道设置，看看问题是否得到解决。 5. 固件配置问题：检查您的设备固件配置，确保WIFI连接参数（如SSID、密码、加密方式等）正确无误。 6. 固件代码问题：检查您的代码，确保在连接WIFI时，正确处理了各种事件和异常。例如，在SYSTEM_EVENT_STA_DISCONNECTED事件中，尝试重新连接WIFI。 7. 路由器问题：路由器可能存在一些问题，导致连接不稳定。尝试重启路由器，或者更换其他路由器，看看问题是否得到解决。 8. 干扰问题：电磁干扰可能影响WIFI信号的传输。检查周围环境，确保没有强烈的电磁干扰源。 9. 固件优化问题：可能需要对ESP-IDF进行一些优化，以提高WIFI连接的稳定性。例如，调整WIFI模块的工作模式、信道扫描策略等。 10. 日志分析：仔细分析异常日志，找出问题的根本原因。例如，分析SYSTEM_EVENT_STA_DISCONNECTED事件的触发条件，以及在该事件中执行的操作。综上所述，要解决这个问题，您需要从多个方面进行排查和优化。希望这些建议能帮助您找到问题的原因并解决它。
