How to update NCP firmwar using OTA ?

[Bhumika]

Hi, 

I am using NRF SDK for Thread and Zigbee V4.0.0.

For updating the firmware of my FTD and MTD devices I am using the thread OTA method described in examples/thread/dfu.

But if I want to update NCP firmware remotely in the field, what changes I need to do in NCP firmware, to update it via OTA method.

Please suggest

Hi,

How did you add and configure the USB DFU trigger library? Have you verified that this is able to enter the bootloader correctly, for instance using nRF Connect programmer app?

Can you upload the full NCP project with added DFU trigger library?

Best regards,
Jørgen
