What is the URI of your Crazyflie and how does your allCrazyflies.yaml look like?

[eduardo-del]

the URI is 0/80/250K/E7E7E7E701

and

allCrazyflies.yaml

`crazyflies:

• id: 1
  channel: 80
  initialPosition: [0.0, 0.0, 0.0]
  type: medium
• id: 2
  channel: 100
  initialPosition: [-1.0, -0.5, 0.0]
  type: default`

The datarate needs to be set to 2M instead of 250K for the Crazyswarm. You can change this setting using the official cfclient.

Okay, I will do it, thank you so much @whoenig , and also for the help on crazyflie_ros.

Hi @whoenig i had the same problem when i changed the URI on official cfclient,
should I change other file or thing?

Thank you so much.

Hello, I also meet the same problem, how do you solve it?

[eduardo-del]

Hi @easy98, no i have the same problem really i didn't follow with crazyswarm.
I'm using crazyflie_ros, but if you want maybe we can help us with crazyswarm and make a solution.

I solved my problem, since I forget to change the vicon's host name in the hover.launch file. Now it works.

Good for you @easy98
