BLE OTA on STM32WB55 does not work when I am using my own application

[MT.2]

Hi there,

I have tried BLE_HeartRate_ota and it works. Yet, when I integrate OTA to my own applicaiton (by uploading BLE_Ota_reference.hex to 0x08000000 first)and try to update the firmware via ST BLE sensor app, the STM_OTA service cannot be connected and the app shows that node cannot be found. Only my application is advertising. My application starts at 08007000 and I have updated the linker file(you can find it in the attachment). "BLE_CFG_OTA_REBOOT_CHAR"  is set to 1 (from ble.config.h) and "SCB->VTOR = VECT_TAB_OFFSET" is removed (from system_stm32wbxx.c). The magic word can be found in app_ble.c(see below). I am using STM32cubeIDE and STM32Cube_FW_WB_V1.0.0. I have no idea what to do so that my OTA application can work.

Thank you for any suggestion!

Cheers,

Mo

Hi @Imen DAHMEN​ ,

The following is missed that's why the reboot request(in app.c) is not handled and OTA service cannot be triggered.

Besides, may I also ask why I sometimes need to go back to the device list (ST BLE Sensor app) in order to connect to OTA service after pressing firmware update in my application? If I use the sample code like BLE_HeartRate_ota, after pressing firmware update, it connects to OTA service by itself. Appreciate any suggestion!
