A Bluetooth WiFi gateway is a device that connects Bluetooth devices to a WiFi network. It allows Bluetooth devices, such as sensors, beacons, or other IoT devices, to communicate with a WiFi network and exchange data with other devices on the network or remote servers or the cloud.
Bluetooth WiFi gateways have both Bluetooth and WiFi capabilities and are able to bridge the communication between these two technologies. They are often used in IoT (Internet of Things) applications, where they can be used to connect a variety of Bluetooth devices to a WiFi network, allowing them to communicate with each other and exchange data.
Gateways are configured through web pages hosted within the gateway itself. These configuration pages allow you to set up the WiFi access point that the gateway connects to, the destination server, typically using protocols such as HTTP or MQTT and determine which Bluetooth devices are allowed to be relayed. The gateway setup also includes filtering options to manage the data sources based on the Bluetooth advertising and/or Bluetooth MAC address. Power for the gateways is generally supplied through a USB connection, which is used solely for power delivery and not for data transfer.
There are also gateways that connect via Ethernet rather than via WiFi.
