Issue using multiple crazyradios on the same laptop
Posted: Tue Jan 26, 2021 9:26 am
Hi,
I've been running a modified version of this script https://gist.github.com/ataffanel/4d5cc ... 2b299ecda9 using 10 CFs, LPS with 8 anchors and three Crazyradios (since the sequence was very unstable in my location using just one Crazyradio)
It was all running fine. Then I decided to try the script with a trajectory https://github.com/bitcraze/crazyflie-l ... h_level.py. That's when I first got the error
So, I tried another script which had been running fine until now that connects to three CFs using two Crazyradios
It now shows the following error
It seems like it connects to one radio but is not able to find the other one. Since, it was working fine earlier, I'm not sure what's causing this error now.
I've never had problems with Crazyradios until now! Please guide me on this, thanks!
OS: Ubuntu 16.04 LTS
Also, I'm able to connect to CF using cfclient without any issues
