Stuck on waitForMessage

[kinkintama]

Hello, I'm trying to use your library to get live data from ant+ devices. I managed to get live data from the device after changing couple of stuff on the driver.py. but the problem is i need to connect multiple devices simultaneously.And i get an error on the second one saying Resource busy.I saw in couple of codes you have a method called get first free channel. The problem is those demos get stuck on waitForMessage. I can only make it work on the demo 08. Is there a way to make that code find a freechannel ? Or how can i not get stuck on waitForMessage in other examples ? Thanks for the help. Below is the message i get when i try to use demo 04.

^CTraceback (most recent call last):

I actually got the example code 4 working with the getFreechannel method in it. But still when i try to connect to my second device i get Resource Busy error
