hello to all,

I have developed an Android app for control Mach4 with bluetooth.
You can find it in Google play store with the name of
"CNC Bluetooth for Mach 4" or click this link https://play.google.com/store/apps/details?id=it.cncbluetooth.cncbluetoothformach4


Available functions:

-Jog functions
-Start / Stop / Feed Hold
-Override feed
-Start and stop spindle
-Home reference

To work you must have the following prerequisites:

-Android version 9 or higher (previous versions of the application cannot be installed as they
do not have some features that are present only from version 9 onwards)
-A PC with bluetooth and a version of Mach 4 installed
No need to install any additional software on your PC!

At this link you can find a configuration guide

Excellent work and excellent documentation Allione, my congrats to you.

Tweakie.

Thank you tweakie

Documentation no longer available and OP not responding to support requests.

Alright, since I bought the app I took a look and it's thankfully simple.
The app acts to emulate a bluetooth keyboard as far as the connection is concerned, this means that you need to have keyboard inputs enabled.

Here is what is mapped to what  (keyboard button = app button):
b  = reset
j = stop
i = pause
h = play
l = spindle on
m = spindle off
k = home
g = rapid rate increase
f  = rapid rate decrease
e = feed rate increase
d = feed rate decrease
PageUp = Z+
PageDown = Z-
LeftArrow = X-
RightArrow = X+
UpArrow = Y+
DownArrow = Y-

If I have time I'll setup the keybinds in script and post it up here.
Still bloody annoying for the dev to not have any support or instructions up.

Good luck folks.
