PageFlip's Bluetooth USB adapter offers Bluetooth 4.0 support for non-compliant PCs. Simply insert the adapter into the computer's USB slot and you will be able to wirelessly connect any PageFlip pedal to your PC via Bluetooth. The adapter is not necessary for iPads and Macs since all Apple products have built-in Bluetooth support. Our adapter uses Broadcom chips for full compatibility with our free software that permits you to reprogram the Firefly and Dragonfly pedal functions.
