Hello.
I've tried to fly one of my Crazyflie and accidentally crash it (not a big deal, it crashed many times without damage). The drone have now the M2 led glowing in blue (without flashing) while the other leds are off. I thought that it's maybe a firmware problem, but when I tried to connect my Crazyflie with USB to my computer, It doesn't seem to detect the connection.
Does my Crazyflie is broken ?

Hi!
Hmmm... usually we will only see this after a faulty flash of a firmware... so I hope the STM mcu is not fried now.
Are you able to put the crazyflie in bootloader mode? Or press the power button for a long time while at the same connecting the battery? Do you see 2 blue LEDs flashing then?

Hi kimberly and thanks for answering.
Yes, it can still be in bootloader mode (the 2 leds works fines) but it still won't be recognized as connected by my PC.
Also, I noticed that the crazyflie can be charged up when plugged on PC, so it's not a USB port problem.

Ah good! If you are able to put it into bootloader mode, then you can reflash the firmware in recovery mode. Please follow these instructions with a crazyradio PA and the CFclient. https://www.bitcraze.io/documentation/r ... very-mode/
Let us know if this works!

That's the problem. The crazyflie can be put in bootloader but when I connect it to my PC with USB, the PC don't see the crazyflie connected. So I can't upload the firmware.

USB unfortunately does not work for this, you must use the Crazyradio

Hello again.
I've successfully accessed my crazyflie in bootloader mode and I've downloaded the firmware in it. Now it's working perfectly.
Thank you for your help, kimberly
