I have followed this https://github.com/matlabbe/rtabmap_drone_example github to simulate rtab.But when I run slam.launch I get the following error : odometry: waiting imu (/mavros/imu/data) to initialize orientation (wait_imu_to_init=true)
mavros interface is changing a lot between the versions, that is why I eventually created a docker example with the right version I tested at that time :)
