pcie to run RM520N-GL 5G module and uses mhi PCIE. How to use Modemmanager
lspci:
0000:00:00.0 PCI bridge: Qualcomm Device 1002
0000:01:00.0 Unassigned class [ff00]: Qualcomm Device 0308
0001:00:00.0 PCI bridge: Qualcomm MDM9x55 LTE Modem [Snapdragon X16]
0001:01:00.0 Unassigned class [ff00]: Qualcomm Device 0308

mmcli -L
No modems were found

I have selected the kernel profile:
CONFIG_MHI_BUS=y
CONFIG_MHI_BUS_EP=y
CONFIG_MHI_BUS_PCI_GENERIC=y
CONFIG_MHI_NET=y
CONFIG_MHI_WWAN_CTRL=y
CONFIG_MHI_WWAN_MBIM=y

But my Modemmanager cannot discover the modem.
Please help everyone~
My pcie has discovered the port device.
But one of my USB 520NGL can't discover the modem either. Unless I turn off mhi related content in the kernel configuration file.
I'm using the latest 6.1 openwrt main.

OpenWrt support for ZBT-Z800AX - IPQ8072A - WiFi6 - 5G Modem (RM520N-GL)

Hello community... I'm starting this new thread because I think this device could be a good option for Wifi6 router combo and 5G modem with external antenna support. I'm not experienced enough to do it alone. So please give your help and ideas to bring openwrt 22.X to this device. Specifications of ZBT-Z800AX : Qualcomm IPQ8072A Qualcomm QCN5024 for 2.4 GHz 4x4 MIMO Qualcomm QCN5054 for 5 GHz 4x4 MIMO AX - Wi-Fi 6 Dual-Band 4+4 (2.4GHz, 5GHz) 4-Lanport Gigabit 1-Wan Gigabit 4-external…

and please don't cross post.

I think you misunderstood, I did not post twice.
I've been able to use openwrt normally.
It's just a matter of PCIE using RM520NGL.
AT+QCFG="data_interface",1,0 // can only be 1,0
AT+QCFG="pcie/mode",0 //EP mode
The Modemmanager cannot be recognized for normal use.

The default Modemmanager seems to be able to dial up. But it is not the qmi method, it seems to be the mbim method. But cannot access the Internet. The firewall is also set up.
