Cloned 1.1.5, on windows 10, Visual Studio 2017, SDK 10.0.17763.0, output is like this for all devices found in the example-scanner.

I added the connect example to my code to try and test out the Warble library, when I ran it I ran into this error:

I've been trying to get the demos to work. I know something works because the scan demo picks up my bluetooth LE Arduino. But it can't seem to find any device info and pauses after the first try. Am I doing anything wrong?

For more info, I'm using a cheap "Panda BT 4.0" USB dongle on the PC side (Windows 10) and using Visual Studio 2019. The Arduino is a Keywishbot Bluetooth Nano BLE module. I don't have any other BLE modules to test with except a second, identical Arduino. I've also tried a few Windows BLE scanner apps that seem to pick up the characteristics alright, so it should be working. Any tips would be appreciated, thanks.

I'm attempting to build Warble on Windows 10 but receive the following error:

warble\cpp\lib.cpp(6,10): fatal error C1083: Cannot open include file: 'lib_def.h': No such file or directory

I downloaded the repo via git clone as mentioned in the build section but there's not a whole lot of details on using it with Windows 10. Is there something I am missing?

Hi, When i try to build the environment for Python SDK by building Warble I get this error in Command Prompt (as admin):
https://github.com/mbientlab/Warble

I get similar errors when I try to build the solution in Visual Studio 2017:

I have installed Python 3.7, FCU Windows 10 SDK (10.0.16299.0) and pip also.

What am I doing wrong? Thank you.

Greetings!

We are trying to compile Your project via pip so as to use the Metawear-SDK-Python on a Raspberry Pi 3 B+.
By following the instructions in the downstream repository (ie: the Python SDK), we have encountered a problem in building the Warble package.

By use of pip to compile, we found that it tries to download the package posted on PythonHosted that actually has the already compiled .o files inside.
These files were compiled for X86-64 (information obtained by `file clibs/warble/deps/libblepp/src/att.o'), and therefore are not compatible with the ARM architecture of the Raspberry.

Given that these files are a dependency of the package, and that pip seems not to be configurable to first call make clean so as to ensure that the sources are recompiled, we ask for informations on how to install Your library for use in other packages.

We attach a file with the compilation result, so as to give a proper context for the problem we found.

Thanks!

On ARM, -m32 should not be required. Building metawear on ARM fails as well, due to this error.

So far this is the only c/c++ cross-platform BLE library I've found; I'm sure there are others somewhere.

I was wondering if it would be reasonable to advertise how supported different platforms are? linux/windows/macosx[/mobile]?
