bglib on linux - not finding com ports #17

Open helen-fornazier opened 9 years ago

helen-fornazier commented 9 years ago

Hello,

I opened the project on eclipse on linux and I am trying to run the CheckBGAPIVersion sample and it seems that it doesn't find any com port, the function getAvailableSerialPorts() is returning an empty list.

Could you help me please?

This is the output of the java execution:

Connecting BLED112 Dongle... Load RxTx for os.name=Linux os.arch=amd64 sun.arch.data.model=64 Current path = /home/helen/workspace/bglib/bglib-samples/.

You have to ensure, that the correct native library is used when running from eclipse. There seem to be in general some issues to keep native lib in sync with the corresponding jar: https://www.google.de/search?q=WARNING:+RXTX+Version+mismatch&ie=utf-8&oe=utf-8&gws_rd=cr&ei=4Z8gVsftF4SMav_rgsgF#q=rxtx+version+mismatch+linux. I used this branch of RXTX on Windows 7/64Bit: http://fizzed.com/oss/rxtx-for-java, they provide also a binary build for LINUX x86_64.

Maybr swithcing to jSSC could help. It should manage that kind of issue transparently and is fairly easily to integrate as a replacement of RxTx (almost same API).
