With this app you can let your device automatically establish bluetooths connection when bluetooth is enabled. It also acts as a Tasker / Locale / LLama Plugin to better cover all your special needs (Connect only if Wifi is disabled). It also supports disconnecting in this mode.
If you use this for tethering, our other App may be useful for you. It must be installed on the device that acts as a internet gateway. The Auto Connect App must be installed on the device where you don't have a regular internet connection (e.g. WIFI only tablet). For instance if you have a Galaxy Nexus and a Nexus 7 Tablet. Auto Tether goes to the Phone and Bluetooth Auto Connect runs on the tablet.
With Version 0.6 we improved compatibility especiallay with A2DP devices. If you still have compatibility issues you can help us getting an overview about what works and what not by filling out this form:
For Galaxy Tab Plus (P6210) users with Android 3.2:
It seems that this app can't connect to other devices because of samsungs own auto connect feature. Users told us that it works with experimental Android 4.0 Ice Cream Sandwhich firmware!

Funcionamento do aplicativo apenas com dispositivos conectados via bluetooth;
Passo a passo:
1- Fazer a montagem no proto board conforme esquema elétrico;
2- Ligar o módulo bluetooth(JY MCU) e Arduino, veja que o led está piscando;
3- No Smartphone ligar o Bluetooth e entrar no aplicativo e pressionar o botão Connect;
4- Observe que o led do módulo bluetooth(JY MCU) estava piscando e quando está conectado para de piscar e fica aceso direto;
5- Os dispositivos estão conetctados via bluetooth - led está aceso direto.
6- Neste momento todos os botões do aplicativo funcionam e enviam dados ao módulo bluetooth e ao Arduino.
Controle remoto com todas as funcionalidades para carros e robos;
O aplicativo ARDUINO RC CAR CONTROL instalado no Smartphone Android controla remotamente o Arduino com comunicação via bluetooth.
Botões de acionamento:
Obs1.: Estes botões foram sujeridos para o projeto mas podem acionar outros dispositivos conforme necessidade.
FORWARD: ACIONA MOTORES(M1 E M2) MOVIMENTO PARA FRENTE;
BACKWARD: ACIONA MOTORES(M1 E M2) MOVIMENTO PARA TRAZ;
LEFT: ACIONA MOTORES(M1 E M2) MOVIMENTO PARA ESQUERDA;
RIGHT: ACIONA MOTORES(M1 E M2) MOVIMENTO PARA DIREITA;
Obs2.: Estes botões também controlam o acionamento e parada ou estacionamento do carro com mudança de cor de verde para vermelho e vive versa.
PARK : ESTACIONAR OU PARAR O CARRO;
SLOW MODE: CONTROLE DE POTÊNCIA DOS MOTORES(MODO LENTO OU BAIXA VELOCIDADE);
TURBO MODE: CONTROLE DE POTÊNCIA DOS MOTORES(MODO RÁPIDO OU ALTA VELOCIDADE);
Obs. Neste projeto os pinos digitais D0 e D1 estão conectados ao RX e TX da placa Arduino e os pinos digitais D2 e D3 estão conectados ao módulo bluetooth, o pino digital D13 está conectado ao led d13 da placa Arduino.
Utilize um smartphone com android, para instalar este “.apk”; Neste exemplo foi utilizado o Tablet Samsung Galaxy GT-P3100 Tab2 7.0” com android versão 4.0.
O aplicativo ARDUINO RC CAR CONTROL instalado no Smartphone com Android comunica com o bluetooth que está conectado à serial(mySerial) pino 2-RX e 3-TX do Arduino que recebe entes dados que por sua vez , interpreta e faz o comando de escrita na porta digital correspondente do Arduino.
Atenção: Quando estiver trabalhando com este aplicativo mantenha a tela sempre ligada(não utilize o modo dormir ou sleep) pois voce pode perder o controle sobre o dispositivo que estão sendo acionados.
Obs.: Para sair do aplicativo, verifique sempre antes se os botões estão todos no modo “OFF”, então pressione o botão “disconnect” e saia do aplicativo; Note que o bluetooth ficará piscando indicativo que o sistema está realmente desconectado.

* Incoming call
* Outgoing call
* Phone charging
* On a Timer (e.g. Every 3, 5, 10 or 15 mins)
* Miracast disconnected
It will then turn off Bluetooth based on your settings:
* When the call ends
* When the Bluetooth connection is lost
* Do not disable Bluetooth
* Miracast connected
Also included is the ability to auto answer call and specify specific Bluetooth devices to speed up connection
Lollipop users please note that its not possible for this app or any 3rd party app to auto answer phone calls. Only Google's apps can do this.
This app is particularly useful for when driving a car where you have forgotten to turn on Bluetooth for your in-car connection.
It will also save your battery as you don't need to keep your Bluetooth on all the time.
Important gear parameters are revolutions per minute per volt (Kv), the engine voltage and the ESC value in percent.
The gear is defined with cog wheel positions at the shaft and the cogs from the cog wheel.
The program has presets for the helicopter: AcrobatSE, Align T-Rex 250SE/450/500/700, Compass Atom 6hv/7hv, EXI 250, GAUI Hurricane 425, GAUI X5, Herobo Embla 450E, MSH Protos, Outrage fusion 50, SAB Goblin 700, Henseleit TDR, Nova7.0
How to use:
- short touch activates / deaktivates the gear wheel
- touch and move changes the cog count
- long touch (1sec) without move changes the gear wheel in a gear belt
- Change it by touching the name or rpm.
+ Now you can use 4 or 7 shafts.
+ new presets: Henseleit TDR, Nova 7.0
+ small changes for android4
+ new presets: Herobo Embla 450E, SAB Goblin 700, EXI 250
+ new presetss: Align T-Rex 700, Outrage fusion 50, Compass Atom 6hv/7hv
+ Look is now android version independent.
+ Menu with icons
- Bugfix in email presets.
+ Shows ratio for pinion to mainshaft and tail to mainshaft (xx:1)
+ save with question and only if you made changes
+ presets now with prefix '~'
+ now you can't modify presets. Changes are stored with no prefix.
+ cogs from wheel can selected a bit better
+ new presets: GAUI X5, MSH Protos
+ Gear parameter revolution per minute per volt has now 5 digits
+ Graphic improvements (number wheel)
+ Menu Help (show the text 'How to use')
- Bugfix: Units
+ new Presets: AcrobatSE , T-Rex 250SE, T-Rex 500 (thanks to Andreas und Rene)
+ Added gear belt to bridge a shaft. (nice idea from Andreas)
+ Added shaft typ name.
+ move to SD card (with Android 2.2)
- Bugfix: after changing engine parameter all values are recalculated
- Bugfix: Values greater than 999999 RPM will be visible as >999999 and don't destroy the layout.
- small patches
+ cogs from wheel can now selected precisely (Thanks for comment from Brian and MarkD)
+ Presets for: Hurrican 425, T-Rex 450 (Thanks for good idea from Brian)
+ In the menu you can select 'email presets' to send me your presets. So i can add them to the next version. By using the menu item, you email client opens with all preset values. You can remove rows you don't want to send. (Help me to generate a good preset list.)
+ Added toast for load and save.
- Bugfix: Load now recalculates all values correct.
- now with function load, save and delete
- Bugfix: small display resolution (HTC Wildfire)
- Number input now nicer
