hi,

is it Possible to make an Update for the Crazyflie PC Client (Or even the Crazyflie itself with this) so it makes an alert noise when
1) the batterie is allmost empty?
2) the crazyflie is allmost out of range or the links signal is really bad?

This would really help to prevent crashes.

is there an easy way to install these tab in my crazyflie VM? I have no clue how to do that and can´t find an nice FAQ part.

You are right. I allready done that after i replaced the motor which was not working AND the Fly is working again. But i have strange disconnects every now and then when flying. Its not even far away from the crazyradio, its like 3-4 meters away.

here we go: bitcraze@bitcraze-ubuntu:~$ cd /home/bitcraze/projects/crazyflie-pc-client/bin/ bitcraze@bitcraze-ubuntu:~/projects/crazyflie-pc-client/bin$ cfclient Info: Using config path: /home/bitcraze/.local/cfclient Info: sys.path= ['/usr/local', '/home/bitcraze/.local/cfclient', '/usr/local/bin',...

i flashed the cflie-2013.4.bin Firmware from https://bitbucket.org/bitcraze/crazyflie-firmware/downloads which results in Self test failed. The strange now is the following: I flashed back to the "Old" cflie_ProductionV2.bin also from that bitbucket page and it is connecting again without ...

so all my problems started after my first attempt to update the firmware, now after the successfull update the hardware is broken? How can this be when the selftest was fine without the update?

I tried to "bang" on all the 4 motorsides but this didn´t help.

Also when i move it around during the powerON it still reads 0,0 as measured value.

The self test was fine before the firmware update (just the M1 Motor wasn´t working) and i also was flying with the flie without problems.

yeah offcourse: here we go with the terminal output: bitcraze@bitcraze-ubuntu:~$ cd /home/bitcraze/projects/crazyflie-pc-client/bin/ bitcraze@bitcraze-ubuntu:~/projects/crazyflie-pc-client/bin$ cfclient Info: Using config path: /home/bitcraze/.local/cfclient Info: sys.path= ['/usr/local', '/home/bit...

With this updated Client i was able to flash the Firmware. Only the verify Flashing option wasn´t working. BUT now the next thing went wrong. When i power on the Flie the Red LED flashes fast like 5 times (i am not able to count that fast :D ) then pauses for 2 seconds and flashes again like 5 times...

here we go with the output at my desktop computer: bitcraze@bitcraze-ubuntu:~$ cd ~/projects/crazyflie-pc-client/cfclient/ bitcraze@bitcraze-ubuntu:~/projects/crazyflie-pc-client/cfclient$ python cfclient.py INFO:__main__:Disabling STL printouts INFO:utils.input:Parsing [Generic_OS_X.json] INFO:util...
