1) GRBLDroidBT will work only with GRBL 0.9+ versions
2) GRBLDroidBT supports simple and advanced file mode.I have followed the official instructions from here :https://github.com/grbl/grbl/wiki/Interfacing-with-Grbl
The simple mode is as described here :Streaming Protocol: Simple Send-Response [Recommended for Grbl v0.9+]
