# Obviously rusEFI supports Bluetooth
rusEFI console has commands for Bluetooth module initialization (see below), at the moment we do not have TunerStudio interface for Bluetooth module initialization.
## Reference Design
https://github.com/rusefi/alphax-4chan is the most popular open source board with on-board bluetooth.
## Isn't HC-06 Dead?
That's an open question see https://github.com/rusefi/rusefi/issues/6197
JDY-33 seems to be the way to go Bluetooth in 2023. Yes, rusEFI supports JDY-33 initialization. Yes, 4chan comes with JDY-33. 2024 update https://github.com/rusefi/rusefi/issues/5918 what a mess
## HC-06 Bluetooth Module serial RS232 TTL
On start, HC-06 accepts AT commands @ 9600.
the default pin is 1234
## JDY
``bluetooth_jdy 115200 alphax 1234``
Which is just one the possibilities
```
// Usage: "bluetooth_hc06 <baud> <name> <pincode>"
// Example: "bluetooth_hc06 38400 rusefi 1234"
bluetooth_hc05 bluetooth_hc06 bluetooth_bk bluetooth_jdy
```
