Setup guides for Bluetooth beacons, repeaters, and gateways

How BLE Tracking Works

1. Beacons

Attached to assets, broadcast BLE signals

2. Repeaters

Extend signal range where needed

3. Gateways

Collect signals and send to your server

Bluetooth Beacon DSC Ver 2.0

A compact Bluetooth Low Energy beacon for indoor positioning, asset tracking, and proximity-based applications. Broadcasts BLE advertising packets for detection by gateways and mobile devices.

Key Specs

•BLE 5.0
•iBeacon & Eddystone compatible
•Configurable broadcast interval
•CR2477 battery (replaceable)
•Up to 2 years battery life
•Compact weatherproof housing

Common Use Cases

•Indoor positioning systems
•Asset presence detection
•Proximity marketing
•Personnel tracking
•Zone-based alerts

Quick Setup Steps

1 Remove the battery tab to activate the beacon. It begins broadcasting immediately.
2 Download the configuration app (iOS/Android) to customize settings.
3 Scan for the beacon using the app. Tap to connect and configure.
4 Set the broadcast interval (shorter = more responsive but shorter battery life).
5 Configure the UUID, Major, and Minor values to match your tracking system's scheme.
6 Mount the beacon on the asset or at the desired location using adhesive or screws.
7 Verify the beacon is detected by your BLE gateway or mobile app.

BLE Repeater V1.0

A BLE signal repeater that extends the coverage of your Bluetooth beacon network. Receives beacon signals and retransmits them to reach gateways that would otherwise be out of range.

Key Specs

•BLE 5.0 receive & retransmit
•USB or DC powered
•Configurable relay settings
•Supports multiple beacon protocols
•Indoor range extension up to 30m

Common Use Cases

•Extending beacon coverage in large facilities
•Bridging coverage gaps
•Multi-floor deployments
•Areas with signal obstruction

Quick Setup Steps

1 Power the repeater via USB or the DC input. No battery — requires constant power.
2 Place the repeater in the coverage gap between beacons and gateways.
3 Use the configuration tool to set which beacon UUIDs to relay (or relay all).
4 Configure the retransmission power level based on the distance to the nearest gateway.
5 Verify by checking that beacon signals from the extended zone now appear at the gateway.
6 For multi-floor setups, place repeaters near stairwells or elevator lobbies.

Bluetooth Gateway BG2 Ver 2.0

A BLE-to-network gateway that receives beacon broadcasts and forwards them to your server or cloud platform via Wi-Fi or Ethernet. The central hub of any BLE tracking deployment.

Key Specs

•BLE 5.0 scanner
•Wi-Fi + Ethernet uplink
•MQTT, HTTP, WebSocket output
•PoE powered
•Scans up to 200+ beacons simultaneously
•Web-based configuration

Common Use Cases

•Indoor asset tracking infrastructure
•Real-time location systems (RTLS)
•Occupancy monitoring
•Environmental sensor data collection
•Facility management

Quick Setup Steps

1 Mount the gateway on the ceiling or high on a wall for optimal BLE reception (central to the coverage area).
2 Connect power via PoE or the USB-C adapter.
3 Connect to your network via Ethernet (recommended) or configure Wi-Fi via the setup hotspot.
4 Access the web management interface at the gateway's IP address.
5 Configure the data output: set your MQTT broker address or HTTP endpoint URL.
6 Set the scan interval and filtering rules (filter by UUID prefix, RSSI threshold, etc.).
7 The gateway will begin forwarding beacon data to your server immediately.
8 Monitor the gateway dashboard to verify beacon detection counts and data throughput.

Troubleshooting

Common BLE deployment issues and how to resolve them

Beacon Not Advertising / Not Discovered

▸
Battery tab: Confirm the battery insulation tab has been fully removed. A partially pulled tab can make intermittent contact.
▸
Dead battery: CR2477 batteries lose charge in storage. If the beacon is new but not advertising, replace the battery and try again.
▸
Wrong scan filter: Your app or gateway may be filtering by UUID. Temporarily disable filters and scan for all BLE devices to confirm the beacon is broadcasting.
▸
Beacon in sleep mode: Some beacons enter sleep mode after configuration. Check if the beacon needs a button press or magnet swipe to wake up.

Weak Signal / Poor Range

▸
Placement: BLE signals are absorbed by the human body and water. Don't place beacons inside metal enclosures or behind large liquid containers. Mount at chest height or above for best propagation.
▸
Broadcast power: Increase the TX power in the beacon configuration app. Higher power = longer range but shorter battery life. Find the minimum power that gives reliable coverage.
▸
2.4 GHz interference: Wi-Fi, microwaves, and other BLE devices share the 2.4 GHz band. In dense environments, reduce the broadcast interval to increase the chance of being heard.
▸
Low battery: As battery voltage drops, some beacons reduce TX power automatically. Replace the battery if signal strength has degraded over time.

Gateway Not Connecting / No Data Upload

▸
Network connectivity: Verify the gateway has an IP address (check LED indicators or the web UI). Try pinging the gateway from your server and vice versa.
▸
MQTT broker unreachable: Check the broker hostname, port (usually 1883 or 8883 for TLS), and credentials. Test the connection with an MQTT client like MQTTX from the same network.
▸
Firewall blocking: Ensure outbound ports 1883/8883 (MQTT) or 80/443 (HTTP) are open. Corporate firewalls often block non-standard ports.
▸
Gateway scanning but not uploading: The gateway may be scanning beacons successfully but failing on the upload step. Check the gateway's system log via the web UI for connection errors.
▸
Wi-Fi issues: If using Wi-Fi uplink, check SSID and password. The gateway's setup hotspot reappears if it can't connect — look for it on your phone to reconfigure.

Repeater Not Extending Range

▸
Placement too far: The repeater must be within reliable BLE range of both the beacon AND the gateway. Place it in the overlap zone — if it can't hear the beacon, it can't relay.
▸
UUID filtering: Check that the repeater is configured to relay the correct beacon UUIDs. If filtering is too strict, it may ignore the beacons you need.
▸
Power supply: The repeater requires constant USB or DC power. Verify the power source is stable — a brownout causes the repeater to drop signals silently.
▸
Duplicate filtering on gateway: Some gateways filter duplicate beacon packets. Repeated signals may be deduplicated — check if the gateway's RSSI reporting reflects the relayed signal.

Firmware Updates

▸
Beacon firmware: Use the manufacturer's configuration app over BLE. Bring the phone within 1 meter of the beacon. Ensure the phone stays awake during the update (takes 1–3 minutes).
▸
Gateway firmware: Update via the web management interface. Upload the firmware file and wait for the gateway to restart. Do not power off during the update.
▸
Update fails: If a beacon firmware update fails, re-insert the battery to reset and try again. For gateways, use the recovery mode (hold reset during power-on).

Battery Replacement

▸
Battery type: The DSC beacon uses a CR2477 3V lithium coin cell. Use quality brands (Panasonic, Renata) — cheap batteries have lower capacity and higher self-discharge.
▸
Opening the beacon: Use a coin or flat tool to twist open the housing. Be careful not to damage the O-ring seal — it provides the weatherproof rating.
▸
Configuration preserved: Replacing the battery does NOT reset the beacon's UUID/Major/Minor configuration. It will resume broadcasting with the same settings.
▸
Expected lifespan: At a 1-second broadcast interval, expect ~2 years. At 100ms intervals, battery life drops to ~3–4 months. Plan replacement schedules accordingly.
