Connecting Vehicle to QGC/MavROS using telemetry #4

Open madhubabuv opened 7 years ago

madhubabuv commented 7 years ago

I am trying to connect the vehicle to QGC through telemetry module provided by you, its showing error with "baudrate mismatch" and when I connect to vehicle from Comm Links it is throwing an error message like " Error on link /dev/ttyUSB0. Error connecting: Could not create port. Permission error while locking the device ".

I have tried giving permission to usb port using "sudo chmod a+wr /dev/ttyUSB0" (in my case it is ttyUSB0), and i restarted the system,restarted QGC still it didn't work.

The same is happening with Mavros also when I am launching the px4.launch like roslaunch mavros px4.launch fcu_url:="/dev/ttyUSB0:57600", it is showing like

The baudrate for Telem is 115200. There is a bug in QGC where it tries to auto connect with serial ports with 57600 baud and doesn't disconnect when demanded to connect with different baud. To circumvent this issue, you can go Comm Link on QGC and manually add device and disconnect and connect telem while pressing Connect on the Comm Link page.
