Bluetooth 4.0 BLE for arduino

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,
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.

-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

SKETCH 2 USING ARDUINO TX, RX PINS

to use the tx and rx pins built in because some arduino do not support software.serial */
// Connect BLE TX to Arduino RX
// Connect BLE RX to Arduino TX, it works in arduino uno, for other arduino model test this connection or
// just connect RX to RX and TX to TX.
