JY-MCU Arduino Bluetooth Wireless Serial Port Module 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, SM 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. Pin definition : * PIO8 connects with LED cathodea with 470ohm series resistor in between. LED NEGATIVE connects to ground. 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.

Very nice! Works great
This works really well. I hooked it up to my Arduino Nano and was running within a few minutes. Using software serial library @ 9600 to communicate with the device and then connected to my laptop and using mini com @ 38400 to communicate over bluetooth. Two way communications established in very little time. Pin code was 1234 and pairing was simple. Using OSX Mavericks. Next I will be seeing if I can configure it for master mode and use it to communicate with and OBD2 device.

A Little Fussy
I was unable to pair successfully with Mac OS X (Yosemite)--tried for hours. The connection is made, but I have never been able to pair this device--the LED always blinks. It's unclear which system is to blame. Perhaps a combination of both.UPDATE: I was able to get this working. You must actually send data to the module soon after pairing on your computer's side. Then, the module will stop flashing and pair properly. If you send no data, it will timeout.

Worked on first try.
Worked flawlessly. I followed this tutorial: http://42bots.com/tutorials/how-to-connect-arduino-uno-to-android-phone-via-bluetooth/ and was able to get it up and running in about 15 minutes or so. I didn't have any issues with the module. It was refreshing to see something working as it should from the get go without having to mess with it. My phone is Samsung Galaxy Note 2 (Android 4.4.2) and the development board is Arduino Uno R3. For my voltage step down (in the tutorial) I used 33K for R1 and 68K for R2.

These are HC-06 (slave modules)
As HC-06 they work great. Giving 3 stars for misinformation in the description - these modules (or at least the ones sent to me) cannot enter master mode, so passive (slave) mode only. To connect two Arduino MC's you need to buy a HC-05 separately.

Easy to use
Works well with very little difficulty in setting up. -1 star because no documentation is included at all. Had to search the internet to find something. Fortunately it was rather easy to find.

It works.
This connects just fine to my Samsung Galaxy, tab2 7", and Note 2. I had a hell of a time getting this to work with my Arduino, BUT THAT WAS MY FAULT, not the module.It shows up as LINVORS and the BT passcode is 1234 (at least mine was).

Works great with Arduino Uno and MYO armband. Very easy to set up and communicate with.
