Unable to set EKF origin on mavros(hector-slam)

hi,
I was trying out hector_slam and cartographer ros using mavros.
I am using jetson-nano as my companion computer and cube-black with Mission Planner(1.3.74.1). I have connected my flight controller through USB_UART and my companion computer is connected through telem2.
Talking about cartographer: I am able to select EKF origin, able to feed mission to ardupilot and works as expected.
Hector_slam:
I have configured exactly as given in the AP doc and hector-slam
I am able to arm and disarm through mavros mavsafety but when I am unable to set EKF_Origin.
when I select “Set Home Here” >> “Set EKF Origin, no error message reads but my rover doesn’t show up in the map and I cannot see any vision position estimates flowing into ardupilot in the messages tab.

when i run: $ roslaunch mavros apm.launch fcu_url:=/dev/ttyUSB1:921600

neither the vision pose estimates flows nor I am getting any errors.
Though I read similar threads related to hector_slam, I did not come across a solution.
Can someone tell me what am I doing wrong in hector_slam?

Hello @siddharth_b,

Did you find a solution? I have the same situation and the same mavros messages, hector_slam do not provide pose to ardupilot. I also tried to remap /slam_out_pose to /mavros/vision_pose/pose, but it did not help.

Did you manage to resolve the issue? I am facing the same problem. Jetson Nano connected to pixhawk through telem2. Connection to the GCS is through udp network. Not able to set the EKF origin as explained in the documentation. Same log as yours.

Hi, Did you solve this problem?, I want to use the hector_slam location, /slam_out_pose, tried remapping, but to no avail.
