Wiimote Level Up not syncing

[phantom]

Hello everyone,

I have searched about this issue but couldn't find a solution at all. Today I bought two 3rd party Wiimote+Nunchuk combos of the brand "Level Up". One of the Wiimotes synced and worked perfectly, while the other just keeps blinking.

I checked the battery and it is full. I also installed the Toshiba Bluetooth Stack to see if there were any changes but no, just one of the Wiimotes is synced.

Does anyone know what could it be? Or how could I check if the controller is fucked up?

Thanks in advance!
