I want to get two values from arduino board via Bluetooth in my android application. The arduino board is already paired to my device. How can i receive those values. Anyone ??
You need to write two applications. one on android and the other on Arduino board. you can refer the following tutorial to connect to bluetooth device from android app.

To start of, i'm REALY new to this so i'm going to need a in depth explanation.
I'm trying to connect my Arduino through Bluetooth to a website. To do this, i'm trying to use the HC-05 bluetooth module. I got the module to work with a app builder and the app bluetooth terminal. I can send text and data to my Arduino.
Now i want to connect it to a website with a pairing button. When clicked, it won't show the device under the pairing tab. I assume this is because it doesn't recognize my module as a pair-able device. Can anyone explain to me how pairing works and if i can get it to connect?
You probably use the Web Bluetooth API on your website, which states (emphasis mine):
The Web Bluetooth API provides the ability to connect and interact with Bluetooth Low Energy peripherals.
Your HC-05 is a Bluetooth Classic device and can not be found using the Web Bluetooth API, which only allows connecting to Bluetooth Low Energy devices. Other adapters will enable you to use BLE with your Arduino; the HM-10 is one of them. Another option would be to switch boards entirely and use something like an ESP32 that already comes with BLE.
I am working on a project that including an android phone that sends simple serial messages to a picaxe microcontroller(14m2) like '1','2','a' etc.
I searched alot on the web, and I only found a way that the android smartphone first "connecting" to the device and "discover" it, the problem is that PICAXE microcontroller is NOT a 'USB' device, and it can't be discoverd by the android, that means the android will not be able to send serial messages to the PICAXE.
if theres any way to send simple pulses from android to PICAXE, please let me know about it.
EDIT: There's any way to do that by connecting the AXE027 download cable with OTG?
I do some project with communicating over serial port. You can use chineese bluetooth adapters (see on ebay arduino bluetooth), those communicate with controllers via Usart and connect to phone by bluetooth. There is sample project Bluetooth chat from google about how to use bluetooth on android. On hardware iside, you can use arduino for receiving data by bluetooth and converting it in format of your controller. You wont have to use any wires
I was wondering if someone could help me out? I am currently running the phonegap desktop and mobile apps. I currently have a BLE board for an a tinyduino. The board is discoverable by BLE discovery applications such as lightblue. In order to achieve this I have used the example HERE
Note the Tinyduino uses the same IDE as Arduino
Along with the BLE board i have 3 sensors attached to my Arduino which are all working fine in the serial monitor.
I would like to use phonegap to create a basic application that receives and displays the serial data from the sensors.
Does anyone know how I would go about doing this?
You can try one of those plugins for Cordova/Phonegap:
Cordova BLE Plugin

Bluetooth LE Cordova Plugin

Have in mind that the target device should support Bluetooth LE
i'm developing an app in android using eclipse and this aplication needs to connect a bluetooth board hc-06 with arduino.
Is it possible connect android only to bluetooth board hc-06? for example, i search bluetooth devices with my app and if i connect with another bluetooth device (without hc-06) the app shows a message like "wrong device".
Set the HC-06's name to something you want. In your Android code check for the name of the Bluetooth connected device. Or, you could check the Bluetooth id, etc.
Is there some way I can send data from an Android device to a computer over Bluetooth?
Thanks
Yes. Perhaps the most straightforward way to get started would be to use the Bluetooth Chat example, which you will hopefully find in the Samples directory of your SDK installation, or can of course be downloaded from Google.
The Bluetooth Chat demonstrates exchanging bytes of data from one Android device to another over the Bluetooth Serial Port Profile (SPP).
To exchange data between the Android device and your computer, you could use a Bluetooth driver on your computer that provides you with a virtual COM port when a remote Bluetooth SPP device connects. This way, you could simply launch Bluetooth Chat on your Android device, and exchange data with something that reads and writes to a COM port on your computer. For example, on a Windows machine you could simply use HyperTerminal.
The Bluetooth Chat example is then an excellent base upon which to create your own custom Bluetooth Android application.
