Receive and send bytes with bluetooth

I want to send numbers but my application only receives them as bytes and not as text, which are parameters, how could I write them in a text bar and send them? I know how to get from the text box and send but not as bytes.

Hello Soren

What Bluetooth are you using? BT Classic or BLE?

HC-06 uses Bluetooth Classic. So, this should work:


(in your case only 2 TextBoxes)
