iOS Connectivity: BLE and VP3350
The VP3350 uses Bluetooth 5.0, 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
VP3350.
It is critical to note that if the VP3350 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.
The VP3350 has a default friendly name of
IDTECH-VP3350-XXXXX
. This is the default name the ID
TECH Universal SDK uses to connect to the first VP3350 it encounters if no other friendly name is set
in the SDK, or when the iOS-generated device identifier is not provided. See links given near the end
of this document for information about the Universal SDK.
Note:
The Universal SDK is primarily of interest to developers. If an application provider or POS
software partner has already provided software to use with the VP3350, you do not need to obtain
the SDK.
