Dear all,
I am using the following devices and driver versions:
- Device: RM520N-GL (RM520NGLAAR01A06M4G)
- Driver: pcie_mhi v1.3.5
- quectel-CM: v1.6.1
I am encountering the following difficulty: When using “quectel-CM,” the program gets stuck at “try to requestSetupDataCall 5 seconds later.”

I have tried executing “apt remove modemmanager,” but unfortunately, the situation did not improve.
