NOTES:
1. For any type of help please use GitHub channel. I can't provide any type of support in google play store comments.
2. On Android versions "Marshmallow" or above, use your OS permission manager and grant "Read External Storage" permission in order to get file streaming working.
3. G-Code files can be placed anywhere in the phone memory or external storage, but they must end with one of the supported extensions .gcoce or .nc or .tap or .ngc
4. If you are connecting Bluetooth module first time to your machine, then make sure you have changed the baud rate of the BT module to 115200. (Default baud rate of the GRBL 1.1v firmware  is 115200 as 8-N-1 (8-bits, no parity, and 1-stop bit)).
6. USB otg only works with grbl baud rate of 115200.
