Overview
The RadBeacon E4 is the next generation Radius Networks Bluetooth™ Smart proximity multi-beacon device. The RadBeacon E4 supports the 4 most popular beacon protocols; iBeacon, AltBeacon, Eddystone UID, and Eddystone URL. The RadBeacon E4 can be configured to advertise data in up to 5 individual slots. The RadBeacon E4 is powered from 4 user-replaceable AA batteries.
User Configuration
The RadBeacon E4 allows for user configuration via the RadBeacon E App available for iOS and Android devices.
Switching the Beacon Off
The E4 can be switched off by disabling all the 5-slots on the beacon using the RadBeacon E app. Refer to the slot configuration section below for details on how to enable/disable a slot.
The button on the side of the beacon is used for enabling configuration-mode. Configuration-mode is entered after pressing and releasing the button while not in configuration-mode. The blue LED will blink twice to confirm beacon has entered configuration-mode. The beacon will remain in configuration-mode for the next 10 minutes. Only while in configuration-mode the beacon will broadcast connectable advertisements.
iOS app user guide
The RadBeacon E App allows users to configure their RadBeacon E4 device parameters.
Scanning
The device scanning process is initiated by pulling down on the home screen of the RadBeacon E App. Next, you should see a progress icon with a message indicating that scanning has started, as shown below.
Beacon Found
After a few seconds of scanning, the home screen should list the available in-range devices. Note: If the Beacon list remains empty after 15 seconds of scanning, we can assume there are no RadBeacon E devices in range.
Beacon Detail
The Beacon Detail screen contains fields for configuring the beacon parameters, and fields that display beacon status information.
Beacon Name
To edit the beacon name, start by tapping on the beacon name edit box under the “Beacon Name” label.The beacon name can be set to a maximum length of 32 characters. If a name containing more than 32 characters is applied as part of the changes, it will be ignored.
Beacon Information
The beacon information section displays status information about the connected device. The “Version” field indicates the firmware version of the beacon. The “MAC address” fields corresponds to the address of the beacon. The “Battery” field shows the current percentage of remaining battery in the device.
Slot Configuration
To start configuring the slots, tap the “Enable” toggle switch to the ON position. Once the slot has been enabled, the list of slot configuration options will expand as shown in the figure below.
Enabled
The “Enabled” switch is used for starting/stopping advertisement activity on the slot.
Channels
The “Channels” option is used for switching advertisement on/off on the 3 individual Bluetooth™ Low Energy advertising channels.
Advertising Interval
The “Advertising interval” value is used for configuring the frequency rate at which the slot advertises data.
The recommended interval value for iBeacon advertisement is 100ms. Increasing the “Advertising Interval” value increases the lifespan of the RadBeacon E4’s battery.
Transmit Power
The “Transmit Power” value determines the strength of the wireless signal transmitted by the RadBeacon E4. The transmit power is proportional to the area coverage of the wireless signal. Increasing the transmit power reduces the lifespan of the RadBeacon E4’s battery. For properly calibrated devices, set the transmit power to +4 dBm for a 30 meters estimated radius of coverage. Refer to the calibration section for more information about how to calibrate the RadBeacon E4.
Beacon Type
The “Beacon Type” screen allows users to configure the advertisement protocol and advertisement data. The RadBeacon E4 supports 4 of the most popular beacon protocols available; Altbeacon, iBeacon, Eddystone UUID, and Eddystone URL. Each slot can be configured to advertise data using one of the 4 beacon protocols. The data advertised varies based on the chosen protocol. See screens below for beacon data configuration examples.
The beacon data could include fields for UUID, Major, Minor, Namespace ID, Instance ID, URL, Measured Power at 0m (0 meters), and Measured Power (at 1 meter).
Data Fields
UUID → Length: 32 characters, Format: 00112233-4455-6677-8899-AABBCCDDEEFF
Major → Range: 0 to 65535
Minor → Range: 0 to 65535
Namespace ID → Length: 20 characters, Format: 00112233445566778899
Instance ID → Length: 12 characters, Format: 001122334455
Measured Power → Range: -1 to -127
The “Measured Power” parameter offers a way to calibrate the beacon’s RSSI at a distance of 1 meter or 0 meters depending on the beacon protocol specification.
