Re: Crazyflie sometimes can't boot after flashing the firmware

Hi, thank you for your help and quick reply! Yes the LEDs are an excellent design choice! I see, unfortunately I get this quite often now, maybe I'm around too many 2.4GHz devices. Do you know what the two red LEDs mean on the other hand? Is it a fail in the same way but just happens later in the co...

Re: Crazyflie sometimes can't boot after flashing the firmware

We have experienced some problems flashing when we flash demos, but usually the fail rate is more like 1 failed flashing every ~0 times.

Crazyflie 2.1 External antenna compatibility

Hi all, I am interested in using an external antenna with the CF2.1 by using the onboard uFL connector (I need to use the RSSI signal quality estimator for a research project, and the value changes too much when the drone's angle varies, because of the location of the included antenna that can easil...
