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 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 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 for current usage...

Current output in https://wokwi.com/projects/new/micropython-pi-pico ...looks very good! :)
