Increasing datarate to 2M will most likely help. You can setup the Crazyflie radio from the client "connect/configure 2.0" menu. First you should connect your Crazyflie 2.0 with the client and then click on "connect/configure 2.0". Once you have written the new configuration, you should restart your...

What version of the VM and of Virtualbox are you using?

One thing that could be happening is that the bus speed is configured too fast. It is currently configured at 400KHz: https://github.com/bitcraze/crazyflie-firmware/blob/master/src/drivers/src/i2c_drv.c#L60 If your sensor does not support 400KHz I2C you can change the code above to set the bus at 10...

Hi, One added comment: By default Crazyflie 2.0 has bluetooth low energy enabled and this is stealing some time from the radio to send BLE advertisement, this is limiting the max bandwidth you can achieve. You can disable bluetooth by building the crazyflie2-nrf-firmware project with the flag BLE=0....

Lets fix the button and the bootloader at the same time then .

The first things is to make sure the tracking is working properly by connecting with the Crazyflie client and flying in position hold mode a...

The current implementation of the kalman filter is supposed to use the z-ranger reading when the Crazyflie is close to the floor and gradually start using more LPS when the altitude grows. So there should be a good match between the z-ranger measured height and the LPS height at this transition, the...

There has been a log-related bug recently that could cause this to happen, are you using the very latest version of the Crazyflie firmware from git?

You need to create and start and add a new log configuration. Each log config corresponds to a log block and a log block is sent in a single radio packets. Radio packets are limited to a size of 32bytes maximum which limits the number of log variables in a block. The limit depends of the size of the...

Are you running in a virtual machine? I installed an Ubuntu 18.04 VM to test and I got the same problem a couple of time, then it started working. My assumption is that the first setpoint command sometime get lost: https://github.com/bitcraze/crazyflie-lib-python/blob/master/examples/ramp.py#L89. If...
