We have Thread devices with bootloader and applicaion based on nRF5 SDK for Thread and Zigbee 2.0, and now we are migrating to SDK 4.1.
As it's stated in documentation the bootloader cannot be updated with Thread Secure DFU, so we need to stay with bootloadter based on SDK 2.0.
Is bootloader from SDK 2.0 compatible with applicatons running Thread Secure DFU based on SDK 4.1 (and newer in the future)?
