Product Description
Allows your device to both send or receive the TTL data via Bluetooth technology without connecting a serial cable to your computer.
This bluetooth bluetooth is perfect for adding bluetooth functionality to your arduino project. But don't think that it is limited to just being used there. Another use you will find for this bluetooth module is with your flight management controller on your quadcopter.
It should be able to be used with several of the available options, so long as the control software supports bluetooth functionality. With this module, you don't have to plug into your flight controller with a micro usb cable every time you want to tweak something, upload a new configuration, or check data.
So long as you are within range,youI can connect to it through bluetooth instead.
There is even an android version of your flight controller software so you can do everything from your phone and not have to carry a laptop with you. Do some googling and you should also be able to find instructions and how-to's for changing the settings on the bluetooth module itself, like the name it uses to identify itself and the pass code for pairing it with devices, along with enabling and disabling different bluetooth protocols.
Note:
1.SPP-CA Bluetooth module serial port level to 3.3V, if connect 5V level,the system needs to increase the level conversion chip.
2.The Bluetooth signal is greatly affected by the surrounding, such as trees, metals, walls and other obstacles will have a certain Bluetooth signal absorption or shielding, we advise do not installed in the metal shell.
3.Due to the metal will weaken the antenna function,we advise when you lay board for the module, the module below the antenna do not shop and alignment, it is best to hollow out.

- Reviewed in the United States on June 29, 2018Color: 1pcVerified PurchaseProgramming the HC-06 was fairly easy to do. The one thing to remember is that these are slave-only mode, so you can't use them as masters. Which is fine for most embedded projects out there. As a result, the HC-06 uses only a subset of the AT commands for programming, such as setting the name, PIN, and baud rate but not being able to get them out of the device's EEPROM.
The range is typical of most Bluetooth devices out there, barring any kind of interference by structures or otherwise. Runs on 3.3V and is well-behaved from what my meter showed, as it was able to sleep with only minimal current drain on the board.
I used this in an Arduino Nano project, which I later transferred to a Teensy 3.6. It was practically seamless jumping from one to the other. I used the SoftwareSerial library for UART communication. After about 15 minutes of fiddling around with it on both boards, I was able to talk to it using my smartphone and my laptop.

- Reviewed in the United States on June 3, 2023Color: 2pcsVerified PurchaseExcellent build quality.
Since these are HC-06 they cannot be configured as 'master'. For interacting with an Arduino (etc.) project and a smartphone (android only) these are ideal - work good, last a long time.
- Reviewed in the United States on April 27, 2020Color: 2pcsVerified PurchaseBoth worked when I started using these but one died after a couple of days. I was using 5v digital data out of a Nano, my bad, I thought the Nanos' had 3.3 volts outputs. The other worked fine after I put a logic level controller between the Nano and the HC-06. Get some Logic level converts if your using 5v outputs like a Nano or uno.

- Reviewed in the United States on January 23, 2020Color: 2pcsVerified PurchaseThis bluetooth board is great for adding wireless connectivity to your embedded projects. It operates in slave-only mode, so something like your smartphone or computer (or a master bluetooth module) needs to initiate the connection. I had it up and running talking to my android phone within five minutes. I needed to download a free bluetooth terminal app from the google play store, but otherwise it really is plug-and-play!
