If your Bluetooth peripheral won’t connect to your Mac, turn it off and turn it on again. If that fails, click the Bluetooth icon in your Mac’s menu bar, then click the peripheral name in question to see if you can connect it that way. If this doesn’t work, in the same menu, select Bluetooth Settings at the bottom. This opens System Settings, with Bluetooth already selected. Click on the ‘i’ icon next to the device in question, and then click Forget This Device. Your Mac and the device are no longer paired. Pair it again (dig out its instructions if necessary).
