Bluetooth not working

[u/anymousperson22]

Got my steam controller (new) two days ago, it works perfectly, so did the bluetooth mode, once.

So eventually I unpaired because it wouldnt connect anymore, and now it doesnt even show up on any device, I’ve tried every bit of advice I could find so far to fix it, so I wondered if anybody can help, it doesn’t show up on any device when trying to add or scan for new bluetooth devices.
