Hello, I bought a 6WD Wild Thumper and T’Rex Motor Controler, but I have different bluetooth modul( HC 06). I saw yours video on youtube (https://www.youtube.com/watch?v=a6E0E-XaE) where you sad, that you had to re-write some code in bluetooth tab. Can you tell me where and what I have to re-write? 
thank you so much
