Port to Linux

[elenzil]

this may function with the current AdaFruit library, we haven't had a chance to test.

I'd be happy to try it out if you can drop in a libWWHAL.so for the Raspberry Pi.

[elenzil]

just saw your comment, @hawflakes . apologies !
i'll see what i can do.

Current AdaFruit library doesn't work, I've tried on RaspBerry. At least the AdaFruit library bluez_dbus also needs modification to add manufacturerData property similar as that done in corebluetooth.

@elenzil how about implement the functions packets2Json and json2Packets (which is currently in libWWHAL.dylib) with Python to make WonderPy compatible with all kinds of operating systems naturally? Thanks!

[liuwencong]

another issue is with Adafruit_BluefruitLE\bluez_dbus\device.py, actual services are not superset of expected services, so the criteria in discover need modification.

actual services
set([UUID('af237777-879d-6186-1f49-deca0e85d9c1'), UUID('00001801-0000-1000-8000-00805f9b34fb')])

expected services
set([UUID('af237777-879d-6186-1f49-deca0e85d9c1'), UUID('af237778-879d-6186-1f49-deca0e85d9c1')])

with above modification and hardcode of robot_type and robot_mode, Raspberry can connect to Dash, then only need the library for linux to do the conversion between JSON and packets of command and response of Dash.

It seems you've made some progress @liuwencong... Was it using libWWHAL.so? If so, where can I find it? I'm also trying to get WonderPy working on a Raspberry Pi but I'm still stuck on #18 unable to install WonderPy.

[elenzil]

Hi All -
many apologies for being so inactive on this project.
i don't foresee myself or other folks at Wonder Workshop being able to contribute much time in the near future, either. :/

but i can provide a few details.

responding to comments in #18, which i'm closing as a dupe of #5:

From what I see, the PyObjC is used to load the native MacOS dynamic library binary "libWWHAL.dylib"

good guess, but slightly off.
PyObjC is a dependency of the AdaFruit bluetooth low energy package,
where it is used to bind to Apple's BTLE services.
I believe it is possible to use the AdaFruit btle package on Linux, but i haven't done it myself.

libWWHAL.dylib is loaded via the regular python library loading methods.
however it is definitely compiled for MacOS, so isn't much good on Linux.
I'll try to carve out some time to compile it for Linux. #5 .

Any luck @elenzil? I could try to compile libWWHAL for Linux myself, if only I had the source ;)

My 2 cents contribution:

https://github.com/adafruit/Adafruit_Python_BluefruitLE

Here you can find the Adafruit_Python_BluefruitLE library for compilation in Linux (including Rasbian).

Also, I have tested this unnofficial git repository and it works in ubuntu!

https://github.com/IlyaSukhanov/morseapi

Maybe, it can be used to improve the official version.
