This may well be a QTM issue, but I thought I'd raise it here in case anyone else finds it useful.
I have:
Deleted all the event short cuts (there were a punch of blank ones, not sure why)
Reset the synchronisation settings for all cameras.

Terminating due to QTM disconnect, reason: EventTrigger

Getting the following error when trying to run example-simple-hover.py:

Windows 10 with Anaconda3, using QTM 1.0.1, cflib 0.1.6, xmltodict 0.11.0

We're able to establish a connection to the aircraft using the crazyflie PC client, so there's no problem with the radio or the aircraft.

If we modify line:

qtmRigidbodies_idxByName[body['Name']] = i

to read:

qtmRigidbodies_idxByName[body] = i

we get the error:

Got link error callback [Too many packets lost] in state [1] Connection to radio://0/80/2M failed: Too many packets lost Terminating due to error while initializing flight controller: Too many packets lost

Any idea on how to fix this?

Cheers
