I am an android developer and new to the bluetooth low energy technology here i am creating an application which is receiving some data packets from a BLE Device (it is like a embedded programmed microcontroller).I am able to connect with the device and then i have to send a command to read the data or the characteristic.I don't know ho can i proceed for the further steps to do that.I have the UUID's and those commands but not able to programme it in android.
Please help me guys.
Thanks
Best Regards

you should read out official tutorial where you can eaislly find how to get data this is link http://developer.android.com/intl/es/guide/topics/connectivity/bluetooth-le.html

I want to send text data through Ios to android using Bluetooth Low Energy Protocol through Advertisements. I have tried alot of code examples but nothing find useful. Please suggest me any working example so i can transmit data in connection less transmissions through advertisements from Ios to android and android to ios. please help my guys. I will be thankful to you !!!
What you want to do is doable but you may need some digging and trial-and-error as there isn't any ready example that I am aware of. To achieve what you want, you have to:-
Send custom data from iOS via BLE advertisements.
Read the custom data from Android via BLE scanning.
You can achieve the first part through one of the examples below:-
Sending bluetooth LE data in advertisement on iOS
Custom BLE Advertisement on iOS
And info on the second part can be found here:-
How can I read the Bluetooth LE advertisement data in Android at the time of scanning
Read advertisement packet in Android

I have searched a lot for the past weeks but have not found any solution. I am new to Android, especially Bluetooth programming. I did read the Bluetooth developer page but it is too complex.
I need to send a String (ex: 40%) continuously from an Android app to another app on a paired Android device without using a button. It should be automatic. I need to know how to identify the paired device and send it the send and how to make the paired device receive this string in its app.
Any help please on how to do that please? I will be very grateful. Thank you.
I have a bluetooth device that collects some environmental data like temperature. I want to build an Android app that will pull the data from this device and display it. The problem here is the device is a kind of non-pairable. It simply works by writing commands on RFCOMM stream.
I just wanted to know if it is possible to create an RFCOMM connection stream without pairing the device in Android? I have tried to look at the other SO posts and blogs but didn't found any useful information.
Any help or pointing in right direction is appreciated.
Thanks
I want to make an application which should send a string over Bluetooth to a micro-controller..I am kind of new to android and don't know where to start..
if anyone could help me with code or what topics i should study to complete this project, it would be great help..
thanx in advance
You could visit the Bluetooth android documentation which shows you how to create a Bluetooth connection and retrieve data: http://developer.android.com/guide/topics/connectivity/bluetooth.html
It is the same basic principle but just need to modify that your android device only connects to the specific address which is your micro-controller. Then, I guess you done. Make sure that your micro-controller understands and can handle your Bluetooth messages.
am developing an application where I can get data from ELM327 and display it on an android device.But I have a doubt,the ELM327 is not controllable,I mean it cant keep sending data automatically to the android device,so how would I be able to pull data from the ELM327.I am really stuck here.So help would be appreciated.Thank you!
Can anyone help me with the type of commands I have to use in android to get responses from ELM 327?How would I only receive speed and rpm?How can I read that data and display it on the android device?
The ELM device is a command/response device which requires you to send a command in order for the ELM to process it, communicate with the ECU system, then format and deliver the response back to you. You won't get unsolicited messages (responses) from an ELM327 chip except on power up when the signature is sent, or unless you set the device into a monitor mode.
The ELM327 is that you use Bluetooth.
I'm trying to make an application to read data adnroid ELM 327, you could.
