In the civilian field, various types of devices that use WiFi and Bluetooth as the prevailing standards occupy a major share of the global market. Therefore, the WiFi and Bluetooth modules used in various IoT devices have grown significantly. In order to optimize the data management of various IoT devices, To meet the growing demand for wireless communication technology in the construction of IoT smart cities, SKYLAB has launched a variety of combination modules and Bluetooth gateway/probe products that integrate WiFi and Bluetooth technologies. In this article, SKYLAB will introduce the workflow and selection points of the Bluetooth gateway/probe (TD03/TD05) in detail.
Bluetooth gateway
TD03/TD05 is a Bluetooth gateway (Bluetooth probe) that integrates two wireless communication methods, WiFi and Bluetooth BLE. WiFi and Bluetooth communicate through serial ports, which can be flexibly used in indoor positioning and health monitoring (such as school students, hospital patient heart rate) etc.), equipment control (remote switching equipment, control equipment).
Workflow of Bluetooth Gateway/Probe (TD03/TD05)
a) Bluetooth scans the broadcast data of surrounding Bluetooth devices (MAC address + RSSI signal value + broadcast content);
b) Bluetooth sends the broadcast data to the WiFi module through the serial port;
c) The WiFi module sends data to the specified server through UDP (default mode);
d) The server sends the data to the WiFi module;
e) The WiFi module sends data to Bluetooth through the serial port;
f) Bluetooth processes data and reports data;
g) Repeat af.
How to choose a Bluetooth gateway/probe (TD03/TD05)?
Before selecting the Bluetooth gateway/probe (TD03/TD05), let's take a look at the parameter comparison between TD03 and TD05:
TD03 and TD05 parameter comparison
At present, the Bluetooth gateway/probe (TD03/TD05) supports scanning the broadcast of the surrounding Bluetooth devices, and broadcasts to the surrounding as an iBeacon. The default UDP method is used to report, and the reporting period is 1 time per second. Among them, Bluetooth supports APP for firmware upgrade, WiFi Support web firmware upgrade. In the selection of Bluetooth gateway/probe (TD03/TD05), the customer must decide whether to choose TD03 or TD05 according to the actual needs of the product application. For example, if the application scheme focuses on the number of connected slave devices and needs to connect multiple Bluetooth bracelets, TD05 is suitable at this time.
