Unable to start offboard mode. RTL after arming

I am trying to start the offboard mode in this example: px4_ros_com/src/examples/offboard/offboard_control.cpp at main · PX4/px4_ros_com · GitHub
as specified by Nuno Marques here:
https://drive.google.com/file/d/1HqxoIAHeYwOskJBH2Dg20vTBdvBOqgEi/view

However, everytime I run the example, I get:

INFO [commander] Armed by external command
INFO [navigator] RTL: landing at home position.
INFO [logger] Start file log (type: full)
INFO [logger] [logger] ./log/2021-01-20/13_17_46.ulg
INFO [logger] Opened full log file: ./log/2021-01-20/13_17_46.ulg
INFO [tone_alarm] notify negative
INFO [commander] Disarmed by auto preflight disarming
INFO [logger] closed logfile, bytes written: 753394

So, it lands to home position right after arming and then gets disarmed right away.
Both COM_OBL_ACT and COM_OBL_RC_ACT are disabled.

Hello,I have the same problem.Did you solve it?thanks.

Same with me - how did you solve it?

The following param settings fixed it for me:

NAV_DLL_ACT = 0
NAV_RCL_ACT = 0
COM_RCL_EXCEPT = 4
