Hello,
I try to control led light of the thingy52 throw a MIT app inventor application.
I use the UUID : ef680300-9b35-4933-9b10-52ffa9740042
and thr characterixtic : ef680301-9b35-4933-9b10-52ffa9740042
I try to send 4 byes : 1 - 0 - 255 - 0, in order to have a green constant light.
But it does not do anything.
When I want to read the characteritics, it send me 2 2 20 172 13.
But I dont understand why the is 13 in th chain.
