Based on the BC chipset, this Bluetooth module will serve as master and slave in one unit, allowing up to 10 meters (roughly 10 yards) or wireless data. You can use this module to communicate between two microcontrollers like Arduino or communicate with any device with Bluetooth. lent Bluetooth Module, it is fully certified to Blue- Radio Chip: CSR BC Memory: 5V voltages out of the Bluetooth module when operated with a 5V host.

Great to put into project and never need to touch again. Thirdly, customer confirms the samples and pay deposit for the official order. At commands cannot be entered again until the connection is broken. Because of this behavior, it may be extremely difficult to do gluetooth entry configuration using Windows Hyperterminal software or similar.

Finally, we arrange the production and shipping. We prefer to fulfill orders under Alibaba Trade Assurance system, since both parties will be protected.

Slave only bluetootg Bluetooth 2. Click to enlarge Price: Arduino Pro Mini – 3. Any changes made will be retained even after power is removed, hence device configuration setup does not need to be repeated unless new changes need to be made.

The main two are; via a serial UART adapter, or, by using an Arduino and a serial-in serial-out sketch. The HC has 2 modes of operation; AT mode and transmission mode. But, the photos in the data sheet feature modules without the logo.

Slave devices cannot initiate a connection which means you cannot link 2 HCs together. The HC enters AT command mode at start up. No MOQ Limit, we welcome any client to purchase the sample for bludtooth purpose. Not Rated Quantity Discount: When powered on the LED flashes about 10 times a second. Here is more correct information: The HC has two operating modes, one is the Data mode in which it can send and receive data from other Bluetooth devices and the other is the AT Command mode where the default device settings can be changed.


You can use this module to communicate between two microcontrollers like Arduino or buetooth with any device blustooth Bluetooth functionality like a Phone or Laptop. Every serial data given to this pin will be broadcasted via Bluetooth. TL — Programmable Reference Voltage. The boards had http: We can operate the device in either of these two modes by using the key pin as explained in the pin description.

I recently bought some HC modules. It is Class1 BT module. Every serial data given to this pin will be broadcasted via Bluetooth 6 State The state pin is connected to on board LED, it can be used as a feedback to check if Bluetooth is working properly. Indicates the status of Module Blink once in 2 sec: The baud rate and PIN cannot be interrogated so take care when setting.

Your email address will not be published. They advertise on BT at Dtasheet and connect just fine. Catasheet can download it at the bottom of the page.

So, if you are not able to complete a command entry within a second, it will be ignored. I normally use the Arduino serial monitor. Do you have any MOQ limit for an order? Any serial stream from to bps can be passed seamlessly from your computer to your target. Do you accept Alibaba online orders? So — the question is, have you come across boards that look like HC, advertise as HC06 but will not respond to AT commands?


Bare in mind the data sheets are from and Ok… problem resolved kind of!

When used with the CSR Bluetooth software stack, it provides a fully compliant bluetooth system to v2. During power up the key pin can be grounded to enter into Command mode, if left free it will by default enter into the data mode.

Wireless communication between two microcontrollers 2. EDR, up to 3Mbps Interface: The Bluetooth Module does not wait for any termination character for each AT command entry. There are many android applications that are already available which makes this process a lot easier. Do you provide samples?

Use of USB to Serial converter cable that can work at higher bauds may be necessary to re-establish a connection. You can use it straight out of the box as a UART wireless cable replacement, without any need to add set-up codes in your microcontroller application.

Everything received via Bluetooth will be given out by this pin as serial data. Two others were the same as each other, had no identifying marks on the module and did have pushbutton pads.

I have an Arduino sketch that tries to communicate at a list of available speeds. I have received a few comments about HC and HC modules that use a new breakout board new to me at least. The information on difference between HC and HC is not entirely correct. Is it free or extra? The HC is a Bluetooth 2.
