Hi
I have the gt king pro device without dongle, I had this problem when starting the new version of coreelec, the control stopped working, luckily I was able to solve this problem by trying different ways, and since I did not find a topic that this I wanted to share it with you to solve the issue and ask the coreelec team to inform me
Well, then enter the Setting / Coreelec / Bluetooth, and then hold the + / UP button to control and then get it with the device.now pair by control
When you turn off the device and returns the control, the control is not connected to fix the problem down / - Take together then drop both and re-hold only - hold
Congratulations, you succeeded
