Serial Port Bluetooth Module(Master)-Arduino Compatible
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.
Default serail port setting: *****0(optional ***0, ***0, ****0), N,
8, 1
Pairing code: ***4
Running in slave role: Pair with BT dongle and master module.
Specification:

Voltage: *3.3V *0mA (2.7V— 4.2V)
Current: Paring - *5mA, Connected - 8mA
Temperature: **0~ **5 degree
User defined Baud rate:
**0, ***0, ***0, ****0, ****0, ****0, *****0, *****0, *****0,
*****0, ******0
Dimension: *6.9mm**3mm*2.2mm
Coupled Mode: Two modules will establish communication
automatically when powered.
PC hosted mode: Pair the module with bluetooth dongle directly as
virtual serial.
Pin Definition:
Common Pin Explanation:
1, PIO8 connects with LED cathodea with **0ohm 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.
2, PIO9 is used to control LED indicating paring. It will be steady
on when paring is successful.
3, PIO*1, module state switching pin. HIGH -> response to AT
command; LOW or floating -> regular work status.
4, With build-in reset circuit, reset is completed automatically
after powered on.
Steps to set as master mode:
1, Set PIO*1 HIGH with a *0K resistor in between.
2, Power on, module comes into AT Command Response Status
3, Open HyperTerminal or other serial tool, set the baud rate
****0, 8 data bits, 1 stop bit, no parity bit, no Flow Control
4, Via serial port, send characters "AT + ROLE = 1 r n", if
successful, return "OK r n", where r n is carriage return.
*0, Set PIO*1 LOW, re-power, then in Master state, automatically
search for slave module and connect.
Application:
Computer and peripheral devices
GPS receiver
Industrial control
MCU projects
