Hello, Sorry for the late reply to update my status over this task. 1] Issue of 0 padding while doing a fota over cellular is resolved. It was a data copying issue. 2] second difficulties was while fetching the data from server using http, which is also resolved by adding required flow for it. Just ...

Hello, Am using ESP32S3 in my project, having esp-idf version 4.4.0 I need to encrypt and decrypt the data using encryption algorithm. Am looking forward to use elliptical curve cryptography for the same, but couldn't find the APIs. I came across the issues 'https://github.com/Mbed-TLS/mbedtls/issue...

Thank you axellin.
will do that.

Hello All, we have designed a data logger using esp32s3, and device wakes up after every set time, and collects data from sensor and goes to deep sleep. But suddenly system is facing a issue where device is not waking from deep sleep after setting a time of 10mins. Kindly note the below behaviour: 1...

Hello ESP_Sprite, I changed data fetching routine from quectel BG95-M5 file to esp-flash. Now I am getting below error when writing is completed.

Hi ESP_Sprite,

Thank you for your reply.
Will definitely try the approach you suggested, will share the results.

Hi @ESP_Sprite, Sorry for late reply. below are the fota logs which is taken when fota is done using wifi and gsm modem. -> Flash write log when WIFI: Total Write binary data length: 1201296 I (56101) esp_image: segment 0: paddr=00250020 vaddr=3c0e0020 size=317f8h (202744) map I (56181) esp_image: s...

Hi @ESP_Sprite I compared both the files i.e. original .bin and 'ota partition read' .bin file in ascii. Missing part is something like below, but why I don't get it.. I got this : " rtc_clk_xtal_freq_get() == RTC_XTAL_FREQ_40M soc/esp32s3/clk.c res d'esp_clk_init vfs_err == ESP_OK && "Failed to reg...

Hello, @ESP_Sprite As you suggested, i have used esptool and read OTA partition, in my case I wrote new .bin from 0x250000. You are perfectly right. Even though i have received correct number of bytes from server with header(which am bypassing while actual writing in a ota partition), some of the da...

Hello,

@ESP_Sprite Thank you so much for the suggestion. Will check the comparison as you have suggested.
Will share what I get.
