Scan Advertisements
Collect beacon and sensor advertisements from gateways, filtered by device address, name or service.
Protocol Support
BLE Integration
Scan advertisements and read GATT services through BLE gateways, to track assets, rooms and short-range sensors.

- Advertising data, or GATT services and characteristics
What BLE Is
Bluetooth Low Energy is the short-range radio built into phones and countless small sensors. A device either broadcasts advertisements that any nearby scanner can hear, or accepts a connection and exposes GATT characteristics. A BLE gateway sits in the room, listens, and forwards what it hears so a signal strength or a reading becomes data.

How IoTServa Connects BLE
Read GATT Characteristics
Connect through a gateway and read standard services such as environmental sensing and battery level.
Presence and Proximity
Use signal strength from several gateways to tell which room an asset or tag is in.
Reduce the Noise
Drop duplicates and unknown devices at the gateway so only meaningful readings travel upstream.
Typical Jobs
- Asset and equipment tagging
- Room-level presence and occupancy hints
- Short-range environmental sensors
- Commissioning and maintenance checks
Plan for These
Radio range depends on walls and metal. Position gateways by testing, not by floor plan alone.
Advertising data is public. Do not put sensitive information in a broadcast.
Phones and many tags use random addresses, which changes how you identify a device.
BLE Questions
Does IoTServa connect to BLE devices directly?
It works through BLE gateways in your premises, which scan and forward data over IP.
Can IoTServa locate assets?
It can estimate which gateway or room a tag is nearest to from signal strength. It does not claim metre-level positioning.
