OTA Updates for STM32C091

Hi Team,

This is Vamsi. I am using a smart display with the STM32C091 MCU and would like to implement OTA updates for this chipset. Could you please suggest the best possible way to achieve this?

OTA refers to updating the firmware over the air. For ESP32 chipsets, we typically use HTTP requests to download the file and perform the update wirelessly. However, I'm not familiar with the exact procedure for STM32. Please let me know if you need any additional information from my end.

No info required from your end,  as i write on first message 091 dont have over air connect then OTA is impossible.
