The syntax used is
BLEBeacon=i,<name_for_logging>,<uuid>,<major>,<minor>

<name_for_logging> is an optional setting, up to 15 characters long, to allocate a name to this BLE beacon that may be reported. An example use would be a VTAP PRO reader in Cloud mode returning this name, as part of the tap information sent to a customer application, to indicate which beacon was being advertised at the time of the tap.
<uuid> is the UUID (unique identifier) of the beacon to advertise. You can use any value. If intended for use with Apple Wallet passes, the UUID must match that entered in the location field of the pass.
<major> and <minor> are decimal values (0 to 65535) that must be specified as part of the BLE beacon advertisement. A beacon detecting application can be configured to trigger when a specific UUID, and optionally specific major and/or minor numbers match those being advertised. For example, an Apple Wallet pass might use wildcard values to match any major or minor values with a specific UUID, or it might be set to only trigger when a specific UUID and major number is detected. This allows, for instance, detection of all branches of a franchise, or only those in specific regions (based on a matching major), or individual locations (based on matching major and minor).
