Are BLE over-the-air firmware updates supported for STM32WB0 series?

[Adrian Adamson]

I currently have a product that uses the STM32WB55 microcontroller, and we have developed a phone app that has all of the user interface to the product, and it also performs OTA updates.

I'm working on a new product and I'm considering the STM32WB0 series to save size and cost, but so far I'm not finding support for BLE-based OTA firmware updates.  Is there a hardware reason why this would not work?  Why are there no BLE OTA examples?   I can only find OTA update examples using the proprietary 2.4 GHz radio protocol.  This won't work for updating directly from a phone.

I found the answer in the release notes for the STM32WB0 Cube repository:

"FUOTA framework is not supported in STM32WB05xx devices due to memory constrains."
