When the crazyflie is in bootloader mode, m1 and m2 are blinking slowly and all the other leds are off. If you crazyflie is in this state, follow these instruction from 'download latest firmware' to flash a complete newest release for both NRF and STM: https://www.bitcraze.io/documentation/tutorials...

Hi! So in this paper there was a full system identification done on the crazyflie 2.0 by eth zurich, which is very similar to the 2.1 for the exception of the IMU: https://polybox.ethz.ch/index.php/s/20dde63ee00ffe7085964393a55a91c7 For simulations: you can also consider using Gazebo and the hector ...

Hi! Hmm yes good question. It is fine as long as you are not changing the commander type I believe. If you just use the regular commander: https://github.com/bitcraze/crazyflie-lib-python/blob/master/cflib/crazyflie/commander.py, it has both functionalities for sending angle setpoints and position v...

For accelerations, you can check out these logging values in the logging tab of the cfclient or in your script for the global coordinates: stateEstimate.ax, .ay, .az (https://github.com/bitcraze/crazyflie-firmware/blob/9e47ecfe69677b785f54fe6167f5a6ce048642ba/src/modules/src/stabilizer.c#L646-L648) ...

Then you should look at the motorPowerSet parameter. https://github.com/bitcraze/crazyflie-firmware/blob/9e47ecfe69677b785f54fe6167f5a6ce048642ba/src/modules/src/power_distribution_stock.c#L114-L120. If you set these parameters from a script (don't forget to enable it), you are able control the raw ...

Good that it resolved itself. It seems indeed from your description that the battery was very low. In general, be careful of completely draining the battery. Lipo batteries don't like that and you will lose battery quality if this happens too often. If the LED is red, stop flying and recharge immedi...

Thanks for notifying the forum on your fix of your problem! Let us know if you experience any other problems

Hi, So you want to develop a controller offboard on your own computer? Sure, that would be perfectly possible with the crazyflie python library . You can then send set-points for roll pitch yaw rate and trust (see examples/ramp.py as an example), if that was the level of control you are looking for....

Hmm this is indeed a strange issue... Currently we don't have a crazyflie 1.0 at our disposal since we are working from home. I'll throw this in the group with bitcraze veterans to asks what might be the problem. In the mean time, could you also downgrade the cflib to one from 2017 ? (I think you ca...

I would like to suggest to install the client from 2017, but unfortunately somebody on a similar thread tried the same: https://forum.bitcraze.io/viewtopic.php?f=5&t=4218. We are a bit unsure on how to fix this, so I will discuss it with the rest and get back to you. In the mean time, keep an eye op...
