DFU CHARACTERISTICS NOT FOUND

[Andreas]

Hello,

I am working with DFU in the nRF Connect App and its working fine.
Now I want to switch to the Android-DFU-Library
and I always get "DFU CHARACTERISTICS NOT FOUND".
Also when I use the nRF Toolbox, I get the same Error.

What is the diff between nRF Connect App and nRF Toolbox and how can I fix this?
Does someone have an idea?

Based on just what you wrote, looks like your device is based on nRF Connect SDK, not nrf5 SDK.

nRF Connect for mobile support both: nrf5 based legacy and secure dfu and NCS based mcu mgr based dfu.

Try nRF Connect Device Manager library, you'll find it on our GitHub. 

If the fw of your device is actually based on nRF5 SDK, all apps and DFU lib should work.
