ESP32S3官方例程wifi->station多块板测试连接不上WiFi是怎么回事？

问答对人有帮助，内容完整，我也想知道答案 0 问题描述：运行的程序是wifi->station程序 1.我们自己画的PCB板子，以前用过ESP32,ESP32S2在连接WiFi上均没有问题，现在在ESP32S3时，连接不上WiFi。 2.板子搭载了一个xn297无线模块，拆掉该无线模块后还是不行 3.蓝牙功能均没有问题，甚至可以用蓝牙进行OTA更新 4.WiFi打开时，明显有反应，就是连接不上 5.已经在多块PCB板测试，均是如此以下是运行日志： ESP-ROM:esp32s3-20210327Build:Mar 27 2021rst:0x1 (POWERON),boot:0x8 (SPI_FAST_FLASH_BOOT)SPIWP:0xeemode:DIO, clock div:1load:0x3fce3820,len:0x1718load:0x403c9700,len:0x4load:0x403c9704,len:0xc08load:0x403cc700,len:0x2f08entry 0x403c990cI (27) boot: ESP-IDF v5.2-dev-921-gdc016f5987-dirty 2nd stage bootloaderI (27) boot: compile time Jul 24 2023 08:46:47I (28) boot: Multicore bootloaderI (32) boot: chip revision: v0.1I (36) boot.esp32s3: Boot SPI Speed : 80MHzI (41) boot.esp32s3: SPI Mode : DIOI (45) boot.esp32s3: SPI Flash Size : 8MBI (50) boot: Enabling RNG early entropy source...I (56) boot: Partition Table:I (59) boot: ## Label Usage Type ST Offset LengthI (66) boot: 0 nvs WiFi data 01 02 00009000 00006000I (74) boot: 1 phy_init RF data 01 01 0000f000 00001000I (81) boot: 2 factory factory app 00 00 00010000 00100000I (89) boot: End of partition tableI (93) esp_image: segment 0: paddr=00010020 vaddr=3c080020 size=20624h (132644) mapI (125) esp_image: segment 1: paddr=0003064c vaddr=3fc96f00 size=0448ch ( 17548) loadI (129) esp_image: segment 2: paddr=00034ae0 vaddr=40374000 size=0b538h ( 46392) loadI (141) esp_image: segment 3: paddr=00040020 vaddr=42000020 size=7c168h (508264) mapI (233) esp_image: segment 4: paddr=000bc190 vaddr=4037f538 size=078e0h ( 30944) loadI (248) boot: Loaded app from partition at offset 0x10000I (248) boot: Disabling RNG early entropy source...I (260) cpu_start: Multicore appI (260) cpu_start: Pro cpu up.I (260) cpu_start: Starting app cpu, entry point is 0x403753000x40375300: call_start_cpu1 at C:/Espressif/frameworks/esp-idf/components/esp_system/port/cpu_start.c:154I (0) cpu_start: App cpu up.I (278) cpu_start: Pro cpu start user codeI (278) cpu_start: cpu freq: 160000000 HzI (278) cpu_start: Application information:I (281) cpu_start: Project name: wifi_stationI (287) cpu_start: App version: 1I (291) cpu_start: Compile time: Jul 24 2023 08:46:33I (297) cpu_start: ELF file SHA256: b1566ee4d...I (302) cpu_start: ESP-IDF: v5.2-dev-921-gdc016f5987-dirtyI (309) cpu_start: Min chip rev: v0.0I (314) cpu_start: Max chip rev: v0.99 I (319) cpu_start: Chip rev: v0.1I (324) heap_init: Initializing.

答案对人有帮助，有参考价值 0 根据您提供的问题描述和运行日志，我们可以按照以下步骤来排查和解决问题： 1. 首先，确认您的ESP32-S3开发板的固件版本是否与官方例程兼容。您可以在ESP-IDF的GitHub仓库中查找与您的开发板型号和固件版本相匹配的例程。 2. 检查您的WiFi配置是否正确。确保SSID和密码与您要连接的WiFi网络匹配。您可以在代码中找到以下部分并进行修改： ``` const char ssid = "您的WiFi名称"; const char password = "您的WiFi密码"; ``` 3. 检查您的PCB板子上的天线是否连接正确。如果天线连接有问题，可能会导致WiFi信号接收不良。 4. 检查您的WiFi信道设置。ESP32-S3支持的信道范围可能与您的路由器设置不同。您可以在代码中找到以下部分并进行修改： ``` wifi_config_t wifi_config = { .sta = { .ssid = SSID, .password = PASSWORD, .bssid_set = 0, .channel = 0, // 设置为0，让ESP32自动选择信道 }, }; ``` 5. 检查您的ESP32-S3开发板的电源供应是否稳定。不稳定的电源可能会影响WiFi模块的正常工作。 6. 如果以上步骤都无法解决问题，您可以尝试升级ESP-IDF到最新版本，并重新编译和烧录程序。 7. 如果问题仍然存在，您可以考虑在ESP-IDF的GitHub仓库中提交一个issue，描述您遇到的问题和相关配置，以便开发者帮助您解决问题。希望以上步骤能帮助您解决ESP32-S3连接不上WiFi的问题。
