B4R by B4A

[Marc DANIEL]

Some time ago, a B4X user asked me this question: "Do you know any two-line displays that can be controlled via Bluetooth or WiFi?" I answered: "probably" and had fun proving it here. Of course this project could be improved by using your Smartphones keyboard with the use of the B4A "IME" library

Of course, these applications can be used for a 4 line by 20 character LCD display, just modify the B4R application​

And I had fun adding a small keyboard to write on the LCD screen, the typed characters are transmitted via their ASCII codes to the B4R application, this gives a new completed B4A application and a new B4R application. The eraser still works as well as the test button.
