# mkconnect-python
...a bit of code to connect to MouldKing Bluetooth Hubs in python.

# MouldKing Hubs
## MouldKing 6.0 Hub
The MouldKing 6.0 Hub has two modes:
* RC-Mode to be controlled with a MouldKing remotecontrol
* Bluetooth-Mode to be controlled with an app

You can control a maximum of three MK6.0 Hubs at the same time with bluetooth.
> (Currently this project can send only one advertising telegram the same time - so only one hub can be controlled, all others will go in timeout-mode till next telegram with their device address is sent.)

## Setting the address of the Hub
To switch the Hub's device address to the next one (device 0, device 1, device 2) just press the button on the hub.

> i.E.: If the script runs with **mkcontrol(2,0,1)** (-> device2, channel0, full speed forward) and nothing is happening, you have to short-press the button, perhaps again...)

# usage
Start the script [consoletest.py](https://github.com/J0EK3R/mkconnect-python/blob/main/consoletest.py) on your raspberry:
```
pi@devpi:~/dev/mkconnect-python $ sudo python -i consoletest.py 
```

## mkbtstop() - stop bluetooth advertising
```
Ready to execute commands

>>> mkbtstop()
```

## mkconnect() - switch hubs in bluetooth mode
If you power-on the hubs they will listen to telegrams to the **first device by default**.
Call mkconnect() to switch all hubs in Bluetooth mode.
By short-pressing the button on MK6.0 Hubs you can choose the hubId:
* hubId=0 - one Led flash
* hubId=1 - two Led flashs
* hubId=2 - three Led flashs
```
Ready to execute commands

>>> mkconnect()
```

## mkcontrol(deviceId, channel, power and powerAndDirection)
i.E.: mkcontrol(0, 0, 1) - on first device (deviceId=0) run channel A (channel=0) with fullspeed (powerAndDirection=1)
```
Ready to execute commands

>>> mkcontrol(0, 0, 1)
```

## mkstop(deviceId)
Set all channels of device to zero
```
Ready to execute commands

>>> mkstop(0)
```

# old stuff

There is a testscript [consoletest.py](https://github.com/J0EK3R/mkconnect-python/blob/main/consoletest.py) where (on raspberry pi) **hcitool** is used to advertise telegrams over bluetooth.

Maybe you habe to **sudo** the command:
```
pi@devpi:~/dev/mkconnect-python $ sudo python -i consoletest.py 

Ready to execute commands

For connecting: mkconnect(hubId) ex: mkconnect(0) or mkconnect(1) for the second hub

 Available commands: mkconnect(hubId)
 mkstop(hubId)
 mkcontrol(deviceId, channel, powerAndDirection)

ex: mkcontrol(0, 0, 0.5) ; mkcontrol(0, 'B', -1)
 the minus sign - indicate reverse motor direction
```





Just look in [main.py](https://github.com/J0EK3R/mkconnect-python/blob/main/main.py) for current usage...

...looks very good! :)
