Hey, will a SDK/Toolchain for the Umidigi UWATCH3 be released? That would be really could since there are some features missing for this watch I'd like to implement, or at least kernel source?
That is not a good enough excuse considering you are obliged to publish the source code under the GPLv2 license.
Edit: And also, any source code you do publish must also be able to be built with just the published files, and function correctly, as per the GPLv2.
