ESP32 OTA Update via HTTPS

Implement Esperssif ESP32 OTA (Over-The-Air) updates via HTTPS with the ESP-IDF framework. you can use this project as a template.

SourceCode

Github: https://github.com/walidamriou/ESP32_OTA_Update_via_HTTPS

Notes

Tools used:

• Platformio (https://platformio.org)
• VScode (https://code.visualstudio.com)
• ESP-IDF (https://docs.espressif.com/projects/esp-idf/en/stable/get-started/)

Development notes

• If you start a new Platformio project, use:
  • monitor_speed = 115200 in platformio.ini (in platformio.ini file)
  • board_build.partitions = partitions_two_ota.csv (in platformio.ini file)
  • #CONFIG_PARTITION_TABLE_SINGLE_APP is not set (in sdkconfig file)
  • CONFIG_PARTITION_TABLE_TWO_OTA=y (in sdkconfig file)
  • #CONFIG_PARTITION_TABLE_CUSTOM is not set (in sdkconfig file)
  • CONFIG_PARTITION_TABLE_CUSTOM_FILENAME=”partitions.csv” (in sdkconfig file)
  • CONFIG_PARTITION_TABLE_FILENAME=”partitions_two_ota.csv” (in sdkconfig file) you can see this edit in the example.
• Functions & API:
  • put firmware_status.json , partitions_two_ota.csv , update.c , update.h , update_info.h , wifi.c and wifi.h in /src folder.
  • Edit firmware_status.json and put the current firmware version and the url when we can get new one, this file we call it from the server, in the example I use it directly from the src folder because I upload it to github.
  • Edit update_info.h and put the current firmware version that you upload to the board with the url when we can get new one.
  • Edit wifi_info.h and put the username and password of the wifi.
  • in your main.c call this functions with this order:
    wifi_init();
    wifi_connect();
    int a = check_updates(); //if there is new firmware, check_updates() return 1 if not return 0
    if(a==1){
    update();
    }
  • you can play with the last functions. For example, you can call it when a click button or an event happens, but with the same order.
