Hello,
Do the softdevice stack support wireless firmware update through BLE?
Thank you! Joseph
Hello,

Thank you! Joseph
Nordic has an example of a bootloader that can be used to upgrade the firmware but it is not doing it over the air. We have implemented a bootloader that initializes the SoftDevice stack and provides a firmware upgrade service.
I our case we have an external spi flash where we buffer the firmware image before we write it to internal flash, but as long as you're careful not to write to flash while the radio is active it should be possible to do without an external buffer. Radio notification can be used to see when the radio is active.
Good luck.

Hi Jimmie,
Thanks for sharing this with me, are you referring to the ble_app_hrs project for the bootloader example? Could you tell me which file I should look at for the bootloader source code?
Thank you! Joseph
There is a folder caller nrf6310_experimental that gets installed with the SDK. It contains sample code for a bootloader.

I got it, thank you very much!
Joseph: If you found this answer useful, I'd be happy if you could accept it to clear up the discussion and show appreciation! :-)
