Hi, nordic engineer:
Our project has a function, that is, BLE+Thread coexists. We hope that the mobile phone can upgrade the device through BLE. Can this idea be realized? I tried to burn softdecvice+bootloader, then use the mobile phone to give the device DFU. After the upgrade is completed, let the device power off and restart, the device does not jump to the application, but enters DFU mode again.
At the moment, DFU through BLE for our Thread examples are not possible.
You can do DFU with Thread, like this example shows, check this tutorial for that.
I will inform the development team about this feature request :-)
Thank you very much for your reply so fast. Yes, I know that there is DFU function of open thread, but we have an idea. We want to connect a device with a mobile phone and then upgrade it by BLE. Give a device upgrade instead of all. Equipment. Can this be achieved?
Unfortunately no, at the moment this is not possible. I have as I said informed the development team about this feature request :-)
