Share My Creation Gcode generator using B4A

With the help of the B4A Brazil group, with the help of this forum and with a lot of research, I managed to create this font Gcode generator. The APP screen and the generated file are attached.
Also attached is the machine that I designed and built to machine the letters on PET identification plates.
Thank you all.

Looks great!

The next steps are:
1) implement bluetooth connection
2) send and receive esp32 grbl messages

If anyone can help me in this task, I'm very grateful. I've been reading something on the forum, but nothing definitive, lots of bug reports, I just want to be able to send and receive messages from ESP32 with B4A.
