FOTA using GSM module

Postby snehapawar# » Fri Jan 27, 2023 11:30 am

Hello All,

I am using esp32s-esp-idf for my project, and in our application, have successfully implemented wifi-OTA.

Now, as a feature, am trying to do fota using questel's gsm module.



-ESP32S
-ESP-IDF v1.5.1
-Quectel's BG95
-partition table
nvs, 0x01, nvs, 0x11000, 0x8000,
otadata, 0x01, ota, 0x19000, 0x2000,
phy_init, 0x01, phy, 0x21000, 0x3000,
ota_0, 0x00, ota_0, 0x110000, 0x140000,
ota_1, 0x00, ota_1, 0x250000, 0x140000,
fatfs_storage, 0x01, fat, , 4M,



Please find my flow of code.
-http get request using gsm modem
-download .bin file from aws s3 server(successfully)
-this file is saved in Quectel's file system
-read file data of 1kb at a time and flash into esp(got no error while writing to flash)
-when esp_ota_end(update_handle) is been called, got error as 'ESP_ERR_OTA_VALIDATE_FAILED' i.e. 'Image validation failed, image is corrupted'
