Thread Secure DFU

[xiang san]

Hi,

I have a question about 'Thread Secrue DFU',according to the 'https://infocenter.nordicsemi.com/index.jsp' ,the 'Thread Secrue DFU'  does not use softdevice of transform components, So does it support multi protocol  OTA DFU? example Ble_Thread protocol，because the Ble will used softdevice.

Thank you very much ,I also want to supprot DFU over BLE in the bootloader ,can you provide me with an example, which will be of great help to me

Hi,

Like I said, we do not have any examples showing this. You need to compare the configurations from BLE Secure DFU Bootloader and the bootloader from Thread Secure OTA DFU Example. Then you need to combine the required configurations for both protocols to be enabled, and add some logic in the merged bootloader to distinguish between a reset from Thread DFU application and a boot into starting BLE DFU procedure.

Best regards,
Jørgen
