How do you communicate with HC 05?

How do you communicate with HC 05?

Connecting Phone to HC-05 Bluetooth Module In order to pair the module with your phone, open Bluetooth Settings in your phone and connect to “HC-05” with pin “1234”. If 1234 doesn’t work, try “0000”. Once the Bluetooth Module is paired with your phone, you can start using the App.

How do I program my HC 05 Bluetooth module?

Android App interfacing with HC-05

1. Create an empty project on Android Studio.
2. Create a ListView containing all the available bluetooth devices.
3. Get the name and MAC-address of HC-05 module.
4. Open connection with HC-05 module.
5. Instruct the module with data as bytes.

How do I connect my HC 05 to my phone?

Follow these mini-steps:

1. Connect the Rx and Tx pins of HC-05 back to Arduino (if you haven’t did this already).
2. Pair the device with your mobile phone (in my case I am using Android OS and my phone is Samsung SII).
3. Download “Bluetooth Terminal” app from Google Play Store.
4. Open Bluetooth Terminal app.

How does Bluetooth module HC 05 work?

HC-05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC-05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds. This module works on 3.3 V.

Can we connect Arduino to mobile?

Finally, the Arduino can be connected to the microUSB port using the OTG Cable. The app should auto-start. Now send some text and the same data will be echoed back! Download the code for this project here.

What are the specifications of the hc-05 Bluetooth module?

HC05 module is a Bluetooth module using serial communication, mostly used in electronics projects. HC05 Bluetooth module important specifications: Working voltage: 3.6V – 5VInternal antenna: YesAutomatic connection to the last device: Yes HC05 module has an internal 3.3v regulator and that is why you can connect it to 5v voltage.

Do you need a serial connection to use a hc-05?

Using an HC-05 often requires an initial hardwired serial connection. Most how-to s describe using some sort of USB-to-serial adapter, often an Arduino board, for access to the module’s “command” mode from a PC. I’d rather have a widget that I can just stab an HC-05 into and carry on.

How does the hc-05 module work on Arduino?

HC-05 modules connect serial and Bluetooth devices using the Bluetooth Serial Port Profile (SPP). Many in the Arduino community have described how to configure and use these modules, including several Instructables. Using an HC-05 often requires an initial hardwired serial connection.

What are the commands for hc-03 and hc-05?

The most common commands for HC-03 and HC-05 are: AT+ROLE (set master –slave), AT+CMODE ( set address pairing) , AT+PSWD (set password). If you want the master module has the function of remembering slave module, the most simply way is: First, set AT+CMODE=1. Make the master module pair with the slave module.
