Bluetooth Data Transparent Transmission

Basic Concepts

As shown in Figure 1, a Bluetooth data transparent transmission system consists of multiple Bluetooth clients, one or more APs with built-in Bluetooth modules, one or more ACs, and one server.

Figure 1 Mechanism of Bluetooth data transparent transmission

Functions of each component in a Bluetooth data transparent transmission system are as follows:

Bluetooth client: manufactured by Bluetooth client vendors and generate Bluetooth signals based on the BLE protocol. Bluetooth clients obtain users' health data (such as the body temperature measured by Bluetooth thermometers) and periodically send BLE broadcast frames containing users' health data.
AP: scans BLE broadcast frames sent by Bluetooth clients. An AP only parses the header of BLE broadcast frames but does not parse the data field in the frames. An AP obtains MAC addresses and RSSIs of Bluetooth clients from the BLE broadcast frames, and reports the information to an AC or a server.
AC: delivers configurations and sends information in BLE broadcast frames to a server. The information includes users' health data, MAC addresses and RSSIs of Bluetooth clients, and Bluetooth client offline alarms.
Server: parses and obtains users' health data carried in BLE broadcast frames for analysis and management.

Implementation

As shown in Figure 1, Bluetooth data is transparently transmitted as follows:

The built-in Bluetooth module of an AP scans surrounding Bluetooth clients, and collects BLE broadcast frames sent by the clients. BLE broadcast frames carry users' health data, and MAC addresses and RSSIs of Bluetooth clients.

Bluetooth clients periodically send BLE broadcast frames and do not need to access a WLAN.
The AP sends information obtained from Bluetooth clients to an AC or a server. The information includes users' health data, and MAC addresses and RSSIs of Bluetooth clients.
The AC sends information reported by APs to a server. The information includes users' health data, MAC addresses and RSSIs of Bluetooth clients, and Bluetooth client offline alarms.
The server parses and obtains users' health data carried in BLE broadcast frames for analysis and management.
