Tested in MAC OS with Samsung Galaxy S9

[ritgail]

I tested scat in MAC OS, had to install:
brew install libusb
After that, it worked.

As it is said the user plane packet is routed to port 47290, can I get SIP messages in case of VoLTE calls?

It should be (tested with Galaxy S8), but I haven't tested Samsung parsers these days so YMMV.

Hi @ritgail could I ask what settings you were using to get this working. I have a MacOS with Samsung S9 and get the following errors:

Which interface works for you?

Could you please share your S9 firmware version? I cann't get LTE message output with G960FXXU6CSG8. Thanks.

Sorry for the delayed response. Have you activated the DM?
Dial *#0808, then activate DM + ACM + RNDIS, which will open up the new in interface 4 in the USB bus:address, with the endpoints.
Then run normally, layer 3 messages should show up.

Thanks to the team, I am still learning.

Access denied (insufficient permissions)

I think some other program or another hanged python script is still accessing your USB. After you activate DM mode, interface 4 should show. It works for me.
