here I'm not using ST BLE app I'm using my own app

[Issamos]

In this case, I suggest you to try to adapt the steps used with ST BLE  & STM32CubeMonitor-RF to your own application.

Doesn't work for me too in custom project!
I've added ota reboot char, set that define flag to 1, but then even if I attempt to send 0x01 or 0x00 to reboot char there's no reaction. Does it require additional code? That's a pity STM doesn't provide a simple custom project examples with OTA.

I've successfully uploaded the BLE_OTA firmware at memory address 0x08000000 and the BLE_heartrate_ota at 0x08007000. Now, my challenge lies in understanding how to structure the data to write into the reboot characteristic for initiating an OTA firmware update. The specific data format and content for this characteristic remain a bit unclear to me.

Did you find documentation on this? The only really helpful information regarding OTA I found is this youtube video: https://www.youtube.com/watch?v=mRzZOa3jmuM&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=9

and the FUOTA documentation for the WBA platform:
