Re: Bolt not applying thrust to one motor, but responsive(?)

That looks very nice, let's try to get it into the air! Have you been able to check that you get a signal output on M4? I guess that since after 5min M4 actually is starting to run rules out any HW problem with the Bolt. My guess is that there is some calibration settings issue with the M4 ESC. And ...

Re: BigQuad used but the drone is very unstable

Hi, The Kalman filter no longer needs the weight/thrust so nothing to do there. What might need tuning is the different position controllers. If you are using the PID (which is a good start) you should alter the BaseThrust here . The other PID position parameters should work but could also be tuned ...

Re: BigQuad used but the drone is very unstable

We are still lacking a tuning guide :oops: Some pointers you can find in this post. There are tuns of guides on the internet though which might be a good start. Generally a bigquad/bolt will be more powerful so start by reducing RATE P,I and D by half end test. You can use the parameter framework to...

Re: Can't burn firmware into Crazyflie 2.0

I'll jump in as there are a couple of other ways. The iOS client is able to update the Crazyflie 2.X firmware to the latest release. Also it is possible to update the STM32F405 using dfu update over usb.

Re: CF Bolt Motor Override Signals

The Mx_OVERIDE signals was intended to have a dual purpose if one rather run brushed motors but it has not yet been implemented. Instead they are enabling power to the connector and thus to the ESC if it is cabled using the connector. So in the current functionality the naming Mx_ENABLE is much more...

Re: Multiranger deck I2C(frequency )

It is probably a parallelism problem. The Crazyflie is starting the reads in parallel and my guess is that the Arduino is doing it in series and that is why you get a low update rate. On the Muliranger deck the default setup is 10 times/sec for the 5 tof sensors but I'm pretty sure we have tested it...

Re: The type of the AI deck and the colored camera

There is currently no good function to retrieve the color image, and one problem is that the image is JPEG compressed on the GAP8 side which loses some of the information. Otherwise it would be possible to do the Bayer conversion on the PC side but now it is not that good. Here is an github issue ab...

Re: The type of the AI deck and the colored camera

The AI-deck says AI-deck 1.1 on front and backside. If it only says AI-deck it is the 1.0 version.

Re: Bolt Tuning

Tuning can be challenging and something we want to improve. Hopefully soon! 1. You started in the right end. Start with the rate PID values as these has the biggest effect. The attitude PID values often doesn't have to change that much. 2. The kalman filter tuning is a bit easier now and you just ha...

Re: A problem in using ARM-USB-TINY-H and ARM-JTAG-20-10 and setting up the GAP8 SDK

Yep, USB type B might not be so common anymore, good idea, I've added that.

The GAP_SDK is big and not yet that easy to work with. Have you tried the docker variant? This I think is much easier to get started with.
