Feature request: Support of BlueGiga adapters #4

Closed birgander2 closed 5 years ago

birgander2 commented 6 years ago

It would be really cool to additionally support BlueGiga BLED112 adpators through pygatt just like the pyb00st package. This would allow the usuage of your package for people who have only such an adaptor (like me) and enables support for Windows, where pygattlib is not available.

Probably not that complex if you analyse a bit the implementation in pyb00st. If I find some time, I'll maybe try if I can get something running (on Linux, though)

This is great idea. I welcome any code contributions here!

Also, one thing I don't like about pygatt is that it relies on gatttool executable, which means everything will be much slower.

sidikalamini commented 6 years ago

pygatt use gatttool for BlueZ, for BLED112 will use BGAPI. not sure whether BGAPI is faster/slower though

It would be great if somebody would try implementing this and providing PR. My attempts were unsuccessfull.

birgander2 commented 6 years ago

I made some tries last week. I got the notifier running, but the wait_for_devices didn't work as expected. However, I must admit that I have very few experience with all this gatt/bluetooth stuff.

@birgander2 Can you show your code changes? It might be first step into right direction

Dear Andrey Congratulations to this very professional work. I plan to use the Lego Boost set to teach BLE communication, sensor technology and robotics at Reutlingen University (Mechatronics). So I adapted the BlueGiga part of the pygatt library to your pylgbst library. It took me some time, but now your library also runs on Windows 7 using the BLE112 dongle. Unfortunately gattlib als well as bluepy did not work for me on a Raspberry Pi3 and Raspberry Pi Zero W. So I switched for the Linux part to the gatt-python (gatt) library. You can find the source code as well as a (sorry German language) student instruction on my web site https://www.tec.reutlingen-university.de/prof-mack/projekte/python-und-bluetooth-low-energy-lernen-mit-lego-boost/ I had to simplify your library a little bit to get it on a bachelor mechatronics student level ;-) Thank you again for your great work on the Lego Boost robotics set! Stefan

That's cool, Stefan! I will review your code for potential improvements of main repo

I have just released a big change with version 0.6, making changes from @netding code example. It allows now to use different backend libraries, not only gattlib. Can somebody please experiment with installing other libs and trying 4 available connection classes, possibly one of them will work for you? I simply have no Windows OS machine, nor BlueGiga adapters...
