Most of my Bluetooth issues between my iphone or mac are resolved by toggling the H9 bluetooh off, waiting 5 seconds, and then turning it back on.
Press the three X Y Z buttons on the face of the H9 simultaneously to toggle bluetooth on and off. Make sure to wait a few seconds in between.
You’ll know if bluetooth is activated when the blue LED in the upper right corner of the display is lit. The display itself will say “BLUE OFF” or “BLUE ON” breifly during the toggle as well.
