Device firmware update over BLE from STM32 to NRF device

Question

Is it possible to update the firmware from an STM32 device to NRF device over BLE?

What is a step-by-step approach to achieve this? The update procedure includes: Prepare the firmware update, transfer the firmware, verify and execute the updated firmware.

It is unclear to me what you want to achieve. Do you want to update a NRF device by sending the firmware from an STM32 or the other way arround? — Michael Kotzjan

Yes, this is possible. Technically you can do a firmware upgrade of the nRF52 using any BLE device, given that at the end of the day you're just transferring hex packets over BLE. That being said, it is not a trivial task and will probably take weeks (if not months) to implement. Nordic provide libraries for Android and iOS for doing OTA upgrades which might speed up the process, but these libraries don't exist for other platforms (i.e., STM32).

Have a look at the links below as they have references on how to achieve this:
