====My development environment====
1. Ubuntu 14.04
2. QGC 3.1.0 v
3. Crazyflie 2.0 (Uploaded Px4 firmware)
I would like to use "mavros" to output the sensor value or data of Crazyflie to the terminal. However, "CrazyRadio PA" does not support serial connections (CrazyRadio PA uses
a proprietary protocol called "CRTP"). So I have to use the 'mavros.launch' form, and I'm having trouble with fcu_url, gcs_url configuration . Is there a solution?
