Hello, I’m currently facing an issue with connecting the Ping1D sonar to my Pixhawk through telemetry. I’ve followed the instructions outlined in the ArduPilot documentation to set up the Ping1D, and when I connect it directly via USB, everything works perfectly fine. [https://ardupilot.org/copter/docs/common-bluerobotics-ping.html](https://ardupilot.org/copter/docs/common-bluerobotics-ping.html) However, when I try to connect through telemetry, I’m encountering a problem where the parameters are not fully loaded. This is causing some functionality issues that I’m struggling to resolve. ![image](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/6/6a76162594a99bba59ee43745a56c72394be76fb.jpeg) Has anyone else experienced a similar issue or have any suggestions on how to troubleshoot and resolve it? I would greatly appreciate any insights or advice on how to get the Ping1D sonar functioning correctly through telemetry on my Pixhawk. ---

But this was working on mission planner ![image](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/6/6da55ad6df78e9efcb872c500cad2eebb20294a3.jpeg) ---

Hi @Sakthivelj - This [guide](https://bluerobotics.com/learn/ping2-integration-kit-for-blueboat-installation-guide/#software-setup) may be helpful? Have you turned on mavlink messages for the Ping Sonar in BlueOS? ![image](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/3/3d3316679ebcf50253034c57629ec8f939dc29bc.jpeg) To display the sonar range data in QGround Control ( I think this is what you are asking?) you can click the lock icon on the bottom center bar, and then add or edit a value. You’d then select the rangefinder value from the list, like this: ![image](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/b/bbfbfac4a16338773be28dc56f175a452daaf84d.jpeg) That should do the trick! ---

Thanks @tony-white your suggestion sounds promising! I’m excited to try it out. However, I’m also wondering if there’s a way to access ping1d data without using blueos. Any insights on alternative methods would be greatly appreciated! ---

Hi @Sakthivelj - The Ping2 outputs data in serial format, this can be read via USB or directly into a microcontroller. BlueOS just provides a means to ingest this data alongside everything else required for ROV operation - video, ArduSub firmware, etc. Checkout our guide to using the Ping2 with [Arduino](https://bluerobotics.com/learn/using-the-ping-sonar-with-an-arduino/) or you could access on a Raspberry Pi directly via [python](https://github.com/bluerobotics/ping-python). ---

Thanks, @tony-white Enabling the Mavlink distance has resolved my requirements. It’s working well. ---

Hey @tony-white , i have also faced the same problem but in my case i am not using Raspberry Pi or any type of companion computer. [BlueRobotics Ping Underwater Sonar](https://ardupilot.org/copter/docs/common-bluerobotics-ping.html), i have followed this steps in order to connect with the pixhawk, and also while uploading a mission for survey i face so many errors like “Rally Point Transfer Failed” and “Mission Transfer Failed”, but then i disconnect the sonar i don’t face this above issues and the mission gets successfully uploaded. Can you please help me with these two problems without the need of raspberry pi?
