Re: Some details of the lighthouse deployment

The origin is in the openVR space so Y is vertical. So in your case the height of the BS are within ~1cm which seems good.

Re: Some details of the lighthouse deployment

No you shoud not (and you cannot) run room setup without an HMD. Without an HMD the most important is to follow carefully the Triad blog post that is linked in the wiki to setup SteamVR to work without HMD. It is not a problem that the VR compositor crashes, it is actually a good thing: Valve recent...

Re: Some details of the lighthouse deployment

Well, nothing more than two base stations and one tracker.

The link box is used to connect the head-mounted-display (HMD) to your computer so if you setup the system without HMD the linkbox is not needed.

Re: a question about only M2 is blue

From the description you most likely erased the STM32 radio bootloader using DFU. Crazyflie is intended to be programmed using the radio bootloader, DFU is only a recovery mode (as described in the wiki page you linked). If you only program your Crazyflie using the radio bootloader, you will never h...

Re: Crazyradio 2.0 Chrome OS

I have a Chromebook that I have been using occasionally for development when traveling (it has awesome battery life). I have been using crouton to install an Ubuntu chroot. In there I could control the Crazyflie without trouble. I have never tried to do that outside of the chroot and my chromebook i...

Re: Log TOC variables/gyro and acc values

To update to the latest lib and client you can clone both and then: python3 -m pip uninstall cflib python3 -m pip uninstall cfclient cd crazyflie-lib-python python3 -m pip install -e . cd .. cd crazyflie-clients-python python3 -m pip install -e . This will install both the lib and the client in 'edi...

Re: Control Tower Error

It is important that the base-station are well above the crazyflies (at least 40cm above the max flight height) and that they are stable: if the base-station moves even a little bit they switch off until they are stable again, this causes the tracking to stop and it can results in Crash. If you see ...

Re: Log TOC variables/gyro and acc values

If you are using ROS you should start with that :-). I have been assuming you where using the Crazyflie python lib and client since this is what we are developing ourselves. I still think that the problem seems to be on the client side though, not the firmware side: the gyro log variables have alway...

Re: Control Tower Error

No you do not need to keep the HMD on the floor and as I wrote in my last message you do not need to keep SteamVR running.

Re: Log TOC variables/gyro and acc values

The problem might be with the version of your client and lib: A new mechanism has been added a couple of month ago to be able to have more than 255 log variables, you can see if your client is new enough by looking in the console tab. There should be a warning if the new log TOC protocol is not in u...
