| Bluetooth module SKU:TEL0026 From Robot Wiki Contents • 1 Introduction • 2 Specification • 3 PinOut • 4 Set module in AT mode o How to enter into AT mode o Preparation o Steps • 5 Tutorial Introduction This DF-Bluetooth module offers an affordable way to let your microcontroller talk to your Bluetooth devices such as Bluetooth mobile phones, laptop, and Bluetooth adapter. The Bluetooth module provides TTL level UART interface which is supported by almost every microcontroller in the market. It is also designed to be compatible with most popular Arduino controller. Simply plug into Arduino IO Expansion Shield, a Bluetooth Arduino is ready to use. Specification • Chips CSR BC417143 • Bluetooth Protocol Bluetooth Specification v2.0 +EDR • Working Frequency unlicensed ISM Band • Modulation Mode GFSK Gaussian Frequency Shift Keying • Power Class 2 • Transmission Distance in free space • Sensitivity dBm at BER • Transmission rate Asynchronous Mbps Max /160 kbps Synchronous 1Mbps/1Mbps • Security Authentication and encryption • Support profiles Bluetooth serial port • LED indicator LINK • Power Supply DC/50 mA • Working Temperature • Dimension 43x19.3x11mm PinOut Definition RX TTL Level TX TTL Level Set module in AT mode How to enter into AT mode The DF-Bluetooth V3 module has two switches on the module. • The NO.1 switch is used to set the on/off for power saving. • The NO.2 switch AT mode is used to control the Bluetooth module o In AT mode o In Functional mode So if you turn the NO.2 switch on, you can use the AT mode to set the Bluetooth module, e.g. name, baud rate, master/slave mode etc. Preparation • USB to TTL Converter x1 • Bluetooth module x1 • Software CoolTerm, you can also use Arduino IDE serial monitor Steps Part 1 Ready to go USB to TTL module Plug the Bluetooth module into the USB to TTL module Turn on the AT mode switch of the Bluetooth module Connect the USB to TTL module to your computer Install the driver for the USB to Serial module if it can't be recognized. Part 2 Setting After connecting the module to computer, we can use CoolTerm software to talk with Bluetooth module. Click Connection Choose Options to set several parameters in CoolTerm. Set Serial Port Port the port number can be got from the Device Manager of the computer Baudrate 38400 Data Bits 8 Parity none Stop Bits 1 Set Terminal Mode Line Mode Key Emulation CR+LF Set Serial Port Set Terminal Part 3 Setting Send AT command & return value Now use the CoolTerm to send AT commands to the Bluetooth Module and see what information the Bluetooth will answer to the computer. For example • Input at Return OK • Input at+name=DFRobot Return OK • Input at+name? Return:+name DFRobot OK • Input at+role=0 Return OK • Input at+role? Return +role:0 OK |
