Bitcraze VM cfclient cannot use CrazyRadio

[traffens]

Good evening,

This tends to happen anomalously. When I start cfclient via the desktop icon, or when i run the 'cfclient' command, I get an error every time I try to "scan":

Code: Select all

INFO:cfclient.ui.tabs.QualisysTab:Switching Flight Mode to: FlightModeStates.DISCONNECTED
INFO:cflib.crtp.radiodriver:v0.53 dongle with serial N/A founddd
INFO:cflib.drivers.cfusb:Looking for devices....
INFO:cflib.crtp.prrtdriver:Initialized PRRT driver.

    radio = cflib.crtp.radiodriver.RadioManager.open(0)
AttributeError: module 'cflib.crtp.radiodriver' has no attribute 'RadioManager'

Any ideas here as to why this likes to randomly occur? it takes several reboots to get the radio to magically work.

Hi traffens!

This sounds weird! I have not hear about this before. Could I perhaps ask:

1. is this from a VM or natrive?
2. is this Mac? Linux? Windows?

1. This is from the bitcraze VM.

2. the barebones machine is windows 10.

I found that it likes to happen when the drone is OFF. if the drone is ON, this error goes away occasionally.

It sounds like a mismatch between the client and the library. Could you make sure that the lib and cfclient are both latest version?

The RadioManager class was added as public to the radiodriver bout 9 months ago to the library.

Theyre both the "latest" version but my team's been doing development on both, so we were curious if this is a well-known bug, or if something we did has broken the RadioManager class.
