Hi @iamromulan , thanks for writing.
I think I will connect the modem as both PCI (i.e. End Point) and USB at the same time.
Your goal is to connect it to your computer directly using PCIe instead of USB.
Agreed. However I’ll believe it, that it’s connected successfully via PCI, when I see it.
The modem can only be utilized in TE modes as a PCIe Endpoint device. It will not emulate or present itself as any other hardware.
What is TE abbreviation for?
Is AP abbreviation for “Access Point” as in a WIFI (and/or cable ethernet) access point?
In TE modes the IP address(es) is always passed through to the host.
Can you confirm if the RM551E-Gl modem operates DHCP server on both IPv4 and IPv6?
If you have a minute feel free to look at this post too Connect M.2 5G modem to PCI and USB at the same time is supported right? And how configure. (RM551E-GL, RM520N-GL etc.) , asking related question there.
If you have any insights about how the modem appears on Linux and which drivers are needed in Linux for the networking device, please let me know.
Also, do you keep a USB serial connection to the modem via USB for AT commands, at the same time as it’s connected via PCI (for networking)?
Many thanks
