Connection successful in Data Mode. If not specified, than you are probably buying Master pre-set module usually has big white paint mark on the BC chip. In Summary, If one product need to support iOS and Android devices simultaneously, our Bluetooth dual mode modules are the best choice.

HCs are slave only modules and require a master device to make a connection.

The datasheet available from the Taobao sellers is the Wavesen Chinese data sheet. This is a 3. Communicate with Laptop, Desktops and mobile phones 3. Any serial stream from to bps can be passed seamlessly from your computer to your target. Click to enlarge Price: Here is more correct information: Secondly, we quote according to your requirements or our suggestions. We can b417 it directly to the Arduino RX pin.

I double checked the voltage at the divder and was getting just over 3v so added an elegoo psu board and got it up to 3. Hard to know if these are copies or not I suspect they are.

HC (ZG-BW) Bluetooth EDR modules | Martyn Currey

Try a combination of upper and lower case, with and without line end characters. Instead, it acts to whatever character you entered after one second. The Arduino reads 3. Up to around 30 feet 10 m Sensitivity: Pin 34 is only used for HCs. You may need to reset the module before the new name is broadcast.

You can download it at the bottom of the page. It is Class1 BT module. These boards were already configured to work at baud. Indicates the status of Module Bluettooth once in 2 sec: Slave devices cannot initiate a connection which means you cannot link 2 HCs together. Arduino Pro Mini – 3.

TL — Programmable Reference Voltage. Next up is to see if we can talk to them using AT commands. Use of USB to Serial converter cable that can work at higher bauds may be necessary to re-establish a connection.

Here is more correct information:.

Not response to AT commands at all. The HC is a very cool module which can add two-way full-duplex wireless functionality to your projects.

We can operate the device in either of these two modes by using the key pin as explained in the datashret description. How to proceed an order? The state pin bluetoot connected to on board LED, it can be used as a feedback to check if Bluetooth is working properly. Slave only module Bluetooth 2. So, if you are not able to complete a command entry within a second, it will be ignored. Data Logging application 4.

You may use these HTML tags and attributes: When powered on the LED flashes about 10 times a second. There are many android applications that are already available which makes this process a lot bluetioth. You can use this module to communicate between two microcontrollers like Arduino or communicate with any device with Bluetooth functionality like a Phone or Laptop.
