Note: Your device must be compatible to bluetooth 4.0, must be android version 4.3 or higher.
Control an arduino / genuino sending data as 123, abc. This app have predetermined ON/OFF, 6
Control 1 sends variable (1) ON, (0)OFF;
control 2 (3)ON, (2)OFF;
control 3 (5)ON, (4)OFF;
control 4 (7)ON, (6)OFF;
control5 (9)ON, (8)OFF.
To custom labels and String send values check the App "Control for arduino bluetooth 4.0 "
-you can send your own variables. Send a combination to turn ON /OFF 2 or more pins at the same time, for example write 159 and click "send" to Turn ON the pins assigned to those variable.
- Compatible to bluetooth4.0 hm-10 module
- You can use a simple sketch.
Be sure the bluetooth in your device is on, then click on "Select bluetooth" .
Next time you open the app if it is available it will connect to the last ble module you selected
