ZMQ Question

[RDajay]

How do I enable ZMQ for my crazyflie? I've edited the config.json file to enable ZMQ input, but everytime I ran cfclient it shows this message

Aside from that, I can't configure the input device as it does not show the ZMQ input.

It seems as if the ZMQ input us still disabled. Could you try going though the following steps?

• Start the cfclient and select Settings -> Open config folder
• Look in the config folder and find config.json. Close the client first then edit the config.json file to enable ZMQ input:

  Code: Select all

  "enable_zmq_input": true

• Now restart the client and look in the Input device -> Device menu, you should now see one entry that is ZMQ@tcp://127.0.0.1:1212

The ZMQ input device cannot be configured in the client, you have to adjust the values before sending them to the client. Have a look at this example where you can see what data to send.

Thanks, its working now

Is it possible to control multiple quad through this method?

Great! Unfortunately not, the client can only be used for one Crazyflie at a time. If you would like to control multiple then you can either use ROS or have a look at this or this example in the Python library.
