I am using BLE OTA bootloader found in CubeWb1.8.0 to upload a firmware to a custom STM32WB55CG device. I am using ST BLE sensor app to upload the firmware from an android phone to the custom device. I was able to successfully carry out FOTA and restart the uploaded firmware after OTA for some android phones. For some other phones, I was able to upload the firmware and get the Uploaded notification in the ST app but, the device does not restart to run the uploaded firmware in several android phones. What does that mean? Does that mean any issue with indicate characteristic enabling from those android phones?
