create3 / raspberry pi time sync bugs for nav2 #572

How are you connecting to your Create 3?Wi-Fi (ROS 2) Computer(s) Model(s) and Operating System(s)ubuntu 22.04 desktop on laptop Which version of ROS 2 is installed on your computer?Humble Which firmware version is installed on your robot?H.2.3 humble Which RMW is your robot running?FastRTPS Does your robot have an assigned namespace? If so, please share.none Is the robot connected to a network? If so, what is the network type?Yes, home network Are there multiple Create 3 robots connected to your network?No Is multicast enabled?No What is the Adapter Board's USB/BLE Toggle currently switched to?USB Describe your question.Hi, This is what the Raspberrypi says In summary, 192.168.186.3 does not respond to create3's connection request even though it appears to be working normally and 192.168.186.1 configures itself strangely for some mysterious reason and is of course inaccessible by create3. So, DNS problem on the create3 to resolve x.irobot addresses... and an ntp server configuration on raspberrypi which malfunctions and prevents the create3 from synchronizing its clock. the addresses "x.irobot.pool.ntp.org" being uncommented before the last reboot It seems that finally the create3 managed to update its clock 25 minutes after the reboot: ci dessous photos of my create3 with a Turtlebot4 look but I took the raspberrypi out of the dock where it is too hot, I installed it behind the camera OAK support and it is ventilated. Mounted a power hat which expects 21700 batteries and temporary ventilation while waiting for the receipt of an HT fan with information display. First I can try another raspberrypi. but that doesn't fix create3 connecting to 192.168.186.3 Photos of my create3 with a Turtlebot4 look but I took the raspberrypi out of the dock where it is too hot, I installed it behind the cameraOAK support and it is ventilated. Mounted a UPS hat waiting for 21700 batteries and temporary ventilation while awaiting receipt of an HT fan with information display.

install Cyclone DDS on Humble
and put this export line RMW_IMPLEMENTATION=rmw_cyclonedds_cpp in your bashrc
Verified with the create_path example
It's worrying to see that at least since the release of humble the problem has not been resolved.
