Hi @an-ron, > [@an-ron](#): > > But how to show bottom distance in the new QGroundControl 4.2.3 and BlueOS? Ping Sonar MAVLink integration (which allows QGC to show the values) is one of the few Companion software features [not yet available in BlueOS](https://github.com/orgs/bluerobotics/projects/27). That said, the feature has been developed, and is undergoing final cleanup before it gets merged in to the `master` branch, and will most likely be available in a BlueOS beta release within the next week or two. ---

Are there any updates, has it become available in BlueOS now? ---

Hi, It should be available in latest beta. make sure you set RNGFND1\_TYPE to 10 (MAVLink) and RNGFND1\_ORIENTATION to Pitch270 (down) ---

Try rebooting and hopefully that error goes away. it happens somewhat randomly. You _can_ also upload an image file. but rebooting should help. ---

Rebooting didn’t help,sow i use a tar image file to upgrade to 1.1.0-beta.15 it worked fine. I had to activate MAVLink Distances in BlueOS,so it works now Thank you 😀 ![20230216_163536](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/4/4b95b76fb0ada3aa94e38a581cbd6471689f4371.jpeg) ![20230216_163840](https://us1.discourse-cdn.com/flex019/uploads/bluerobotics/original/2X/5/511065f71b077e0eb307905d3099b78bb629cafa.jpeg)
