Pages: [1]. Arduino sending data to Android app via Bluetooth. This might be a very basic question but i'll still ask cause i'm a noob. Explaining the complete project here is irrelevant so i'll just talk about what i want to achieve. I've done all i could but i dont know why the app is not receiving is not displaying what i want it show.

I'm not sure where i'm mistaken. To keep it simple ill just add the relevant part of the code: Code: [Select]. Re: Arduino sending data to Android app via Bluetooth. Try Serial.

Use Your knowledge. If that's not enough, look for education. Having knowledge, think outside the box to gain more of it. Only trains run like the train, on the rails. The rest run between the rails. I tried but wont it print "data from outdoor to app" to the serial monitor. I want "data from outdoor to app" to go get displayed in the app's interface. Is the app properly set up to read the USB port?

If Serial monitor is off it ought to be possible to pick up data from the USB port. Check the difference between Seril. I'm sure the app's code is perfectly fine, cause every where on the internet it says do this and that and i followed it perfectly.Add the following snippet to your HTML:.

No prior knowledge of Android development is needed, however it will help to know some basics of Java programming. I will be using an Android phone for testing purposes and not an Android virtual device. The Android app that you develop can be used with any other microcontroller, I only used the Arduino in this example with the HC bluetooth module since they are both cheap and popular.

I'm going to be creating other posts with different microcontrollers that use this same phone app. Some of the funtionality that I will be using was taken from the offical bluetooth SDK doc. I also derived some ideas from this blog post. I will be making the GUI layout first since it is easier to grasp what we are trying to do via the visual elements. We will be using the LinearLayout Vertical to make our application.

Without a layout manager, your GUI components would arrange themselves differently depending on the screen size of the device. The default layout choice is the RelativeLayout and works by aligning all of the components in relation to the first component placed on the screen or as dictated by you.

Notice how a green line indicates its anchor relationship. Moving the default Hello World! Making an app using this RelativeLayout is straightforward and easy, but often causes headaches with larger or smaller screens than the one you are developing on. Drag the LinearLayout Vertical from the Palette to the component tree. Then drag a checkbox from the Palette to your main activity screen and double-click on it to call it "Toggle LED".

Align it in the middle of the screen. Your Component screen should now look like th. This next portion will be easier to accomplish and convey by just editing the markup XML from the designer. You can view this by clicking on the lower-left hand side of the viewport where it says "Text". If your activity or project name differs from mine, you may need to adjust the tools:context value in the XML to match your settings.

This should be highlighted in red inside the IDE. Nothing difficult here, but note how I used scaleX and scaleY to make this appear larger than the default size. Here is where the data that we receive from the Arduino will be displayed. The demo code on the Arduino will be simply incrementing a bit counter variable.

Note that I used a horizontal linear layout for two textviews.Hi Guys, I have read the question on many forms, How to run small brushed motor for mini quadcopter Hi Guys, In this post, I will demonstrate how you can run or control 6 wired unipolar stepper motor Some time we required to check the RPM of the motor while creating projects. A few days back when Hi there I really like this app you use to control it. Would you please have the source code available?

I need help! I want to make bluetooth controlled 1 ch relay. I downloaded the app from google store. The application is unable to connect with any other devices via bluetooth. Can you please help us how to make that connection. O restante tudo funcionou. Can someone help me please? Ciao io sono nuovo e da poco che adopero arduino ho provato questo progetto con i pulsanti il led si accende e si spegne con il bluetooth mando sul monitor uno zero ma il led non si accende spero mi potete aiutare il progetto e molto bella e utilissimo.

Could anyone help me, please… When I send change value from Arduino Buttons, the status buttons on android doesnt work to me.

What am I doing wrong? Could you please send me the programme of this project!? Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

How to run small brushed motor for mini quadcopter with Arduino adminFebruary 10, July 27,Arduino14 Hi Guys, I have read the question on many forms, How to run small brushed motor for mini quadcopter Ed 5 years ago. Very nice.Bluetooth is one of the popular wireless communication technologies because of its low power consumption, low cost and a light stack but compensates on range.

The basic version is pretty inexpensive. Do remember to remove the jumpers while uploading code to the Arduino if you have selected Pin 0 and 1 as Serial pins.

If the module is being used for the first time, you'll want to change the name, passcode etc. To do this the module should be set to command mode. Connect the Key pin to any pin on the Arduino and set it to high to allow the module to be programmed. If you're using the BTBee, it's a little tricky.

While the official wiki says that the Mode Button must be held to change it to Command Mode, and releasing it changes it back to Data Mode, it doesn't happen that way: instead, hold the Mode button, then quickly press and release the Reset button. You will notice that the Status LED blinks slower than usual. Here's some code to change the name. The jumpers are connected to 4 and 5 because the response from the module will be printed on the Serial Monitor.

The complete code is available at the end of this article in the "download code" button. All data--outgoing and incoming--will have to go through the module. Interfacing the module is that easy. Take a look at the p revious article for a quick intro about Android apps and also the layout for this app. Since the extra hardware this app will be using is the onboard Bluetooth adapter, it will have to be mentioned in the Manifest. If it is present, check if it's enabled. If it isn't enabled, ask the user permission to enable it.

The device must be paired before the app can use it. Check the section below for details on how to pair the BT Module and the Phone. Using the AT Commands from the section above, give an appropriate name to the device. Also find out its MAC Address. Here, the MAC addresses are being compared for a match because names are liable to be changed often.

After getting the BluetoothDevice, a socket has to be created to handle the outgoing connection. Since data can be received at any point of time, running a thread to listen for data would be best. First, the input stream is queried for available data. Then, the bytes are converted to human readable UTF-8 format and the text is send to a handler to post onto the UI.

This is done because the UI can't be updated from background threads. ArduinoBluetooth Source. The name which was set earlier should appear.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. It has associated embedded firmware code to connect to an Arduino to test the bi-directional data stream.

A checkbox and status strings provide functionality to communicate with an embedded microcontroller such as an Arduino. You don't necessarily need to connect an Arduino to still have a functioning phone application.

Other complex profiles are not supported with this example and will fail to connect.

But when I'm sending data from my Android device to my Arduino, the Arduino isn't responding to what I've send. I am able to get a connection from my Android device to my Arduino. So that's not the problem. And what to edit on my script? I have not gone through your code.

But looking at the question, I suggests to keep Arduino FW coding away till Android app is tested and developed to a certain level. The way forward could be:. On the Android side, I'm only including my bluetooth file, which should be easy to fit into your app.

It's main advantage is that after your app start it by calling btConnecteverything else is automatic. It finds and connects to your "HC" without further "human intervention". And if you turn off the "HC", Android will continue watching for the "HC" to come back online, and will auto-connect to it again.

The Arduino Sketch sends a signal once each second. If 10 seconds are missed, the Android assumes the connection has been lost and re-enters connect mode. Learn more. Asked 5 years, 10 months ago.
