Is there any legal issue on reusing a proprietary custom BLE profile?

[Fabio]

Sorry for a non-tech question. I've worked in a project using a ble module from nRF51 serie, and in this project we've implemented the suggested Nordic DFU profile described here (devzone.nordicsemi.com/.../a00081.html), the custom Nordic profile worked pretty well. I have a legacy device which uses a non-Nordic ble module, where I'd like to apply the same implementation I've done to the Nordic one, probably changing UUIDs only. My question: Is there any legal issue on reusing this DFU profile described by Nordic, keeping the same characteristics and attributes on a non-Nordic ble module?

Hi Håkon, thanks for your answer, I understood the license that protects the SDK source code, and I'm accepting your answer as the right one. In fact I'm not intending to reuse/modify the SDK source code itself, the code implementation would be entirely produced by me on both sides (central and peripheral). However, I was tented to base my implementation on the same characteristics, attributes and message sequence as described on Nordic SDK DFU profile. So, worried about the "intellectual" property if it is applicable.

BR, Fabio
