Bluetooth Low Energy, Help !!!

Hi guys !

I'm working on a project, and the arduino must connect to android via bluetooth low energy, I don't know how to make a custom app by android studio to connect to it, I don't know how to make a communication between arduino and android by BLE :(( please help me !!!

Sorry for my English :((

So what do you know?

I know how to make an app on android studio
The problem here is I don't know how to create an app to communicate with arduino by BLE :((

Well, I guess that's the app you need to know about...
Not an Arduino problem.

Thanks for your reply,

But It involve both android and arduino :<

I don't know how to program a BLE communicator on arduino, too :<

I ask this question hope someone who have already done this will answer :<

What's the point of just asking for answer instead of learning how to make it?

Ask to learn :slight_smile:

Let's get back to basics

  • What Arduino board do you have?
  • What BLE module have you got for your Arduino - post a link to the module's datasheet.
  • What do you want the Arduino to send to the phone?
  • What do you want the phone to send to the Arduino?
  • If you have any Arduino program then please post it.

I have an arduino uno R3, a AT-09 module, datasheet: arduino-at-09/hm-10-datasheet.pdf at master · yostane/arduino-at-09 · GitHub , I want android and arduino communicate by simple message like L1 or F1...

I've wrote a program to communicate with android, and I used Serial Bluetooth Terminal to connect and communicate with the arduino and it work perfectly but the point is I can't make a custom app

I've lost my code :((

When you say "custom app" do you mean a program that runs on your phone? If so then this is not the place to get advice. This Forum is about programs that run on an Arduino board.

I've lost my code :((

What program have you lost?

If you wrote the program once, why can't you write it again?

I would get code working which uses the Serial Bluetooth Terminal on the phone. I have had problems with an AT-09 BLE module staying connected to the terminal on the android phone, but if your module works, that's great. Several of the terminal programs have macro buttons which you can name and program to send "L1" or "F1".

If you need a custom app instead of a terminal program then MIT app inventor 2 is the way to go. It does support BLE.
