Hello,
I am attempting to add DFU support for the nRF52832 over Bluetooth, so I am able to update API and firmware in future renditions of code. I was following the tutorial Add DFU support to your application, but I seem to be getting a host of errors and would love some help getting this issue resolved.
I am using nRF connect for VSCode and the 2.4.1 SDK.
I was following the first tutorial and was getting this error (ant help would be gratefully appreciated):
