3.4.1 iOS Connectivity: BLE and VP3320
The ViVOpay VP3320 uses Bluetooth 4.2, also known as Bluetooth BLE (Bluetooth Low Energy). Unlike
previous versions of Bluetooth, BLE does not require users to first pair their devices through the
Bluetooth Settings in Apple iOS. If a payment application provider has enabled BLE scanning in their
application, Apple iOS scans and locates all BLE devices in range to automatically connect with the
ViVOpay VP3320.
It is critical to note that if the ViVOpay VP3320 is paired via the iOS Settings page, it will display as a
connected device but not function with a payment app.
Unlike other operating systems that can detect or specify a BLE device by its MAC address, Apple does
NOT allow users to specify a BLE device by MAC address for security reasons. Instead, after a device is
selected by its "friendly" name (see the next paragraph), the Apple iOS calculates a unique identifier to
allow any that device to make further connections directly.
