Hi.
Testing the Modem Quectel RM520N-GL with WaveShare 5G M.2 TO Gigabit ETH board which also include the chipset RTL8125 for the Ethernet part.
I did some test, but without success:
ATI
Quectel
RM520N-GL
Revision: RM520NGLAAR05A01M4G
AT+QCFG="data_interface",1,0 //NIC switched to pcie mode
AT+QCFG="pcie/mode",1 //Switch pcie to RC mode
AT+QETH="eth_driver","r8125" //Switch the NIC driver to realtake 8125
AT+CFUN=1,1 // Restart module
AT+QICSGP=1,4,"ethernet","","",0
OK
AT+CGACT=1,1
+CME ERROR: 100
Checking the Wireshark trace, the UE is registering, but, when requesting the PDU Session Establishment for DNN=ethernet, the PDU Session Type is ‘IPv4’ and not ‘Ethernet’(as expected):
I did some research and it looks the Modem Quectel RM520N-GL is not capable to request a PDU Session with type "Ethernet’ and should be the core capable for doing this “conversion” (from IP to Ethernet PDU Type).
Did someone experience the same scenario? If confirmed, any updated firmware where this behavior is corrected?
