I use the micropython mindstorms os and when im trying to connect to a xbox controller or to music box via bluetooth it breathly connects but after 2 seconds it disconnects again from the device if i press connect again it sais somthing like Input/output error and in the background it connects and disconnects again. I first thought it is something wrong with the bluetooth of the ev3 but when i tried to connect a wireless keyboard it worked. I also tryed updating the firmware of the controller wich made it not show up for the ev3 anymore so i reset the firmware and now its the same as before. So if someone has also experieced this issue or has an idea how i could fix it pls tell me.
