Reboot 82 | 83 | # 疑难杂症 84 | 85 | * 检查你的 PC 是否能 ping 通 ESP32 的 IP，检查配置菜单中 IP、AP 以及其它配置是否正确。 86 | * 检查是否有防火墙阻止访问你的 PC。 87 | * 通过浏览网址 http://127.0.0.1/ 检查是否可以看到配置文件（默认是 hello-world.bin） 88 | * 如果你还有其它 PC 或手机，可以试试能否看到该文件。 89 | 90 | ## 错误 "ota_begin error err=0x104" 91 | 92 | 如果你看到这个错误，请检查你的分区表，查看所配置的 flash 大小是否足够。默认的 "two OTA slots" 分区表仅能在 4MB 的 flash 上工作。如果你的 flash 小于 4 MB，则需要创建一个自定义的分区表 CSV（查看 components/partition_table）并在配置菜单中对其进行配置。 93 | 94 | 如果改变了分区表的布局，则在这两个步骤之间通常还需要运行 "make erase_flash"。 95 | 96 | ## 产品的实现 97 | 98 | 99 | 如果想在产品中使用这个示例，需要考虑： 100 | 101 | * 使用加密通信协议，例如 HTTPS。 102 | * 初始超时或者烧写过程中的 WiFi 断开的情形 103 | -------------------------------------------------------------------------------- /ota/main/Kconfig.projbuild: -------------------------------------------------------------------------------- 1 | menu "Example Configuration" 2 | 3 | config WIFI_SSID 4 | string "WiFi SSID" 5 | default "myssid" 6 | help 7 | SSID (network name) for the example to connect to. 8 | 9 | config WIFI_PASSWORD 10 | string "WiFi Password" 11 | default "myssid" 12 | help 13 | WiFi password (WPA or WPA2) for the example to use. 14 | 15 | Can be left blank if the network has no security set. 16 | 17 | config SERVER_IP 18 | string "HTTP Server IP" 19 | default "192.168.0.3" 20 | help 21 | HTTP Server IP to download the image file from. 22 | 23 | See example README.md for details. 24 | 25 | config SERVER_PORT 26 | string "HTTP Server Port" 27 | default "8070" 28 | help 29 | HTTP Server port to connect to. 30 | Should be chosen not to conflict with any other port used 31 | on the system. 32 | 33 | config EXAMPLE_FILENAME 34 | string "HTTP GET Filename" 35 | default "/hello-world.bin" 36 | help 37 | Filename of the app image file to download for 38 | the OTA update. 39 | 40 | endmenu 41 | -------------------------------------------------------------------------------- /ota/main/component.mk: -------------------------------------------------------------------------------- 1 | # 2 | # "main" pseudo-component makefile. 3 | # 4 | # (Uses default behaviour of compiling all source files in directory, adding 'include' to include path.) 5 | -------------------------------------------------------------------------------- /ota/main/ota_example_main.c: -------------------------------------------------------------------------------- 1 | /* OTA example 2 | 3 | This example code is in the Public Domain (or CC0 licensed, at your option.) 4 | 5 | Unless required by applicable law or agreed to in writing, this 6 | software is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR 7 | CONDITIONS OF ANY KIND, either express or implied. 8 | */ 9 | #include 10 | #include 11 | #include 12 | 13 | #include "freertos/FreeRTOS.h" 14 | #include "freertos/task.h" 15 | #include "freertos/event_groups.h" 16 | 17 | #include "esp_system.h" 18 | #include "esp_wifi.h" 19 | #include "esp_event_loop.h" 20 | #include "esp_log.h" 21 | #include "esp_ota_ops.h" 22 | #include "esp_partition.h" 23 | 24 | #include "nvs.h" 25 | #include "nvs_flash.h" 26 | 27 | #define EXAMPLE_WIFI_SSID CONFIG_WIFI_SSID 28 | #define EXAMPLE_WIFI_PASS CONFIG_WIFI_PASSWORD 29 | #define EXAMPLE_SERVER_IP CONFIG_SERVER_IP 30 | #define EXAMPLE_SERVER_PORT CONFIG_SERVER_PORT 31 | #define EXAMPLE_FILENAME CONFIG_EXAMPLE_FILENAME 32 | #define BUFFSIZE 1024 33 | #define TEXT_BUFFSIZE 1024 34 | 35 | static const char *TAG = "ota";
