Hi,
I added support for the MSP protocol to ardupilot and while I was at it I also added support for MSP range and flow sensors like the Matek 3901, I don’t have the hardware so I’m looking for testers 
the thread is here
thanks,
Alex

I am using it as an auxiliary positioning for wheeled robots. I have very little knowledge about flight control and have not found any document to decode the data. Only the data format of the MSP protocol is obtained, but the representative meaning of the data is almost unknown.
The following is an example of an intercepted data packet.

24 58 3C 00 01 1F 05 00 FF 2A 00 00 00 C4

I see that you have done research on this and I wonder if you can share your receipt. If you can reply, thank you very much.
I found it in the msp protocol, don’t care about this issue, thank you
Hi Ricky, I don’t suppose you have an STL file for that nice little case you made up? Would you be willing to share it? Thanks!

Here you go.
I never printed it so I don’t know if it actually works. If you need any help with it let me know.

Thank you Sir!
The base is heading to the printer as I type. I’ll report back how it turns out. Not sure if I’ll use the lid or not but I’ll keep you posted.
The shapes are good, but some of the dimensions need a tweak. I’ll see if I can edit the file and if I can I’ll post it here.
Here’s a revision for anyone who wants to try. Big thanks to @rickyg32 for the original!
