Hey! That's a really nice lib you've made! It could benefit from a compression a lot!
Have you done any changes in my lib to adopt it to BLEOTA that should be added to flashz?
I will add a reference to your project in readme
Thanks!

Hi, I didn't change anything, maybe in the future I will integrate in the update class the signature checking, but for now I just copy and paste your files. Thanks!
