New Bluetooth Module Slave Wireless Serial Board Module with PCB for Arduino Description: 1) Wireless serial bluetooth port. 2) With free power adapter bottom board come with well power regulator. User can connect 3.3 to 5VDC and connect TX and RX to your control IO (general 3.3 to 5V digital input output of MCU or arduino IO is ok, or general TLL IO) 3) Easy to connect this module with PC, just search and key "1234" passcode. 4) With white SMD LED on the adapter board, can see the Bluetooth connection status. Step to connect: 1) Connect the wiring, power up, while the device is not connected, the bluetooth module board has a white LED flashing 2) At PC side, search bluetooth device. 3) Found name called "LINVOR" device 4) Connect it, and passcode is "1234" 5) While connection is ok, you can see the LED become always on. 6) Enjoy Basically, user can only use 2 to 5 pin in most of the application Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc. Computer and peripheral devices GPS receiver Industrial control MCU projects Default serail port setting : 9600, N, 8, 1 Pairing code : 1234 Running in slave role: Pair with BT dongle and master module Usage: Coupled Mode: Two modules will establish communication automatically when powered. PC hosted mode: Pair the module with bluetooth dongle directly as virtual serial. Bluetooth protocal : Bluetooth Specification v2.0+EDR Frequency : 2.4GHz ISM band Modulation : GFSK(Gaussian Frequency Shift Keying) Emission power : <=4dBm, Class 2 Sensitivity : <=-84dBm at 0.1% BER Speed : Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps Security : Authentication and encryption Profiles : Bluetooth serial port CSR chip : Bluetooth v2.0 Wave band : 2.4GHz-2.8GHz, ISM Band Protocol : Bluetooth V2.0 Power Class : (+6dbm) Reception sensitivity: -85dBm Voltage : 3.3 (2.7V-4.2V) Current : Paring - 35mA, Connected - 8mA Temperature : -40~ +105 Degrees Celsius User defined Baud rate : 4800, 9600, 19200, 38400, 57600, 115200, 230400,460800,921600 ,1382400. Dimension : 26.9mm*13mm*2.2mm Pin definition : PIO8 connects with LED cathodea with 470ohm series resistor in between. LED NEGATIVE connects to ground. It is used to indicate the module state. After powered on, flashing intervals differ in different states. PIO9 is used to control LED indicating paring. It will be steady on when paring is successful. PIO11, module state switching pin. HIGH -> response to AT command; LOW or floating -> regular work status. With build-in reset circuit, reset is completed automatically after powered on. Steps to set to MASTER: Set PIO11 HIGH with a 10K resistor in between. Power on, module comes into AT Command Response Status Open HyperTerminal or other serial tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, no Flow Control Via serial port, send characters "AT + ROLE = 1 r n",if successful, return "OK r n", where r n is carriage return. Set PIO11 LOW, re-power, then in Master state, automatically search for slave module and connect.
