Enabling Bluetooth

To enable Bluetooth in Rabbit GRBL, all you need to do is add the following two lines at the top of your Machine Configuration file:

// Enable Bluetooth
#define ENABLE_BLUETOOTH

// The device name that will appear during Bluetooth pairing
#define BT_DEVICE_NAME "MyMachineName"

Replace "MyMachineName" with the name you want to appear in the Bluetooth device list of the connecting device (e.g. "MyCNC", "RabbitGRBL", etc.).

That's it! Rabbit GRBL will automatically use Bluetooth instead of USB Serial.

When Bluetooth is enabled, the USB Serial connection is automatically disabled.

Example Configuration with Bluetooth Enabled

Below is a real-world example from the Genmitsu 3030 ProVer machine configuration file (3030_prover_rabbit_board_4axis_1_2_bluetooth.h):

#pragma once

#define MACHINE_NAME "Genmitsu 3030 ProVer"

// Enable Bluetooth
#define ENABLE_BLUETOOTH
#define BT_DEVICE_NAME "Genmitsu3030"

#define N_AXIS 4

#define DEFAULT_STEP_PULSE_MICROSECONDS     5       // $0
#define DEFAULT_STEPPER_IDLE_LOCK_TIME      255     // $1 - Keep motors always on

// ...
