RM500Q-GL in PCIe mode, almost no packets transferred

djgl · February 23, 2022, 8:00pm

I’m trying to connect to the internet using

a RM500Q-GL switched to PCIe mode with AT+QCFG=“data_interface”,1,1
the Quectel Linux PCIe MHI Driver v1.3.0.17
QConnectManager v1.6.1

The issue is that none of the packets I send lead to a response and the only packets I receive are occasional TCP RST and FIN packets from connections of the previous owner of my IP address. Packets sent to the rmnet_mhi0.1 interface correctly get their 14 byte ethernet header replaced with a 4 byte QMAP header and a 4 byte QMAP checksum header before they are sent to the modem via MHI. QMAP packets received do not have a checksum header. I guess that is ok. I tried two SIM cards from different providers and both cards work as expected in mobile phones.

I added a missing #include <linux/ethtool.h> to make the driver compile with Linux 5.15, but other than that it is unmodified. I’m loading the pcie_mhi module with qmap_mode=2 because quectel-CM uses the wrong interface when qmap_mode is 1 (pcie_mhi differs from the USB driver in that it creates a .1 interface for the IP packets even when qmap_mode is 1).

Any idea? I can provide more information if you need.

Isaac.Wang-Q · March 16, 2022, 1:56am

Is the dial-up of QConnectManager v1.6.1 normal? Has the network card rmnet_mhi0.1obtained an IP? Is rmnet_mhi0.1 set as the default route? Can it ping the external network?

djgl · March 18, 2022, 8:43am

The output of QConnectManager looks normal, An IP address is obtained. The interface is set as default route. I can’t ping any addresses.
