As well as allowing a USB connection to (eg) a laptop, this includes a 2.5GBits/s ethernet connection, and providing the RM520N-GL is setup correctly, connects to internet with minimal setup. The AT commands to enable this (from the vendor) are as below:
1, set USB mode: AT+QCFG=“USBNET”,2 2, set to PCIE mode: AT+QCFG=“data_interface”,1,0 3, set PCIE to RC mode: AT+QCFG=“pcie/mode”,1 4, set the PHY model: AT+QETH=“eth_driver”,“r8125” 5, set the dial mode: AT+QMAPWAC=1
ALSO - they say the USB3.0 port and the RJ45 port can not work at the same time.
To switch to USB port:
AT+QMAPWAC=0
What I would like to know is:
a) I have the AT command manual for the RM520N-GL but some of these AT commands above are not listed…
b) The RM520N-GL appears to be acting like a DCHP server - but I can’t find out how to modify this
c) Any further comments would be greatly appreciated!
Dear @radiomean
Please point out which AT commands didn’t list in your document, I will check.
Actullay, I didn’t get your point, what did you want to modify?
i have the same issue here. USB worked but RJ45 does not. My RJ45’s led never light on regardless of mode? Does your RJ45’s led light up? i do not know if my unit is bad or what.
Now my RM520N-GL stuck at AT+QMAPWAC=1 and cannot change back to ‘0’
Any luck? I’m having similar issues, I can get modem to connect via USB but not ETH. I tried a handful of different "usbnet" and "pcie/mode" settings. Currently I have it configured how the first post details but it’s not the same exact device. It’s an MCUZone, seems more modern from this link
It does get IP addresses but I get the feeling it’s not correctly setting up the NAT from the issued DHCP addresses and I can’t figure out how to troubleshoot.
