Useful AT Commands

You can send more than one command at once by sperating them with ; and not including the AT part. AT+QENG="servingcell";+QCAINFO for example to see the info from both AT+QENG="servingcell" and AT+QCAINFO

PCIe RC Ethernet mode setup

For RM500-RM521 modems

AT+QETH="eth_driver","r8125",1;+QCFG="pcie/mode",1;+QCFG="usbnet",1;+QMAP="MPDN_rule",0,1,0,1,1,"FF:FF:FF:FF:FF:FF";+QMAP="DHCPV4DNS","disable";+QCFG="usbcfg",0x2C7C,0x0801,1,1,1,1,1,2,0;+CFUN=1,1

This will do the following:

  • Set the 2.5Gig Ethernet driver as active
  • Enable PCIe RC mode
  • Set to ECM mode via USB and AP mode connection behavior
  • Enable IPPT
  • Enable DNS IPPT (disables onboard proxy)
  • Force Enables ADB Access
  • Reboots after all the above

For x70 modems (RM550/551)

For BETA versions of firmware: the adb value 2 trick still works so one and done:

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1;+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,2,0;+CFUN=1,1

OR if you are running the latest non-beta firmware

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1

Then unlock ADB:

Ask the modem for its adb code by sending: AT+QADBKEY?

It'll respond with something like +QADBKEY: 29229988

Take that number and paste it in this generator: https://onecompiler.com/python/3znepjcsq (hint: where it says STDIN)

You should get something like

AT+QADBKEY="mrX4zOPwdSIEjfM"

Send that command to the modem and adb will be able to be turned on with the next command

Now you can turn it on with the usbcfg command AT+QCFG="usbcfg"

Be super careful, this controls what ports are on/off over USB.

Run it and you will get the current settings. Something like this:

+QCFG: "usbcfg",0x2C7C,0x0122,1,1,1,1,1,0,0

Send AT+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,1,0 to enable adb

Now you can reboot: AT+CFUN=1,1

This will do the following:

  • Enable PCIe RC mode (Driver selection is automatic now)
  • Set to ECM mode via USB and AP mode connection behavior
  • Force Enables ADB Access
  • Reboots after all the above

Tip: APN automatic selection will somtimes choose the wrong APN. You may need to set your APN after powering up with the SIM inserted.

The List

  • AT+CFUN=1,1 (reboot)
  • AT+CFUN=0;CFUN=1 (Disconnect then reconnect)(tip: run this after chnaging APN and you don't have to reboot)
  • AT+QMAPWAC? (get current status of auto connect, 0=disabled 1=enabled)
  • AT+QMAPWAC=1 (enable auto connect internet for ethernet)
  • AT+QMAPWAC=0 (disable auto connect for ethernet; use when you want internet over USB to work; IPPT must be disabled)
  • AT+QUIMSLOT? (get active sim slot; 1=Slot 1; 2=Slot 2)
    • AT+QUIMSLOT=1 (switch to sim slot 1)
    • AT+QUIMSLOT=2 (switch to sim slot 2)
  • AT+CGDCONT? (Get active APN profle st 1 through 8)
  • AT+QMBNCFG="AutoSel",0;+QMBNCFG="Deactivate" (Disable Automatic APN selection)(You will need to set your APN when you switch SIMs or Slots)(Can also set APN after you switch the run AT+CFUN=0;CFUN=1
    • AT+CGDCONT=1,"IPV4V6","APNHERE" (Sets APN profile 1 to APNHERE using both IPV4 and IPV6)
  • AT+GSN (Show current IMEI)
  • AT+EGMR=0,7 (Show current IMEI)
  • AT+EGMR=1,7,"IMEIGOESHERE" (sets/repairs IMEI)
  • AT+QCFG="usbcfg",0x2C7C,0x0801,1,1,1,1,1,2,0 (enables adb bypasses adb key)
  • AT+QENG="servingcell" (shows anchor band and network connection status)
  • AT+QCAINFO (Show all connected bands/CA info)
  • AT+QNWPREFCFG="mode_pref" (Check what the current network search mode is set to)
  • AT+QNWPREFCFG="mode_pref",AUTO (Set network search mode to automatic)
  • AT+QNWPREFCFG="mode_pref",NR5G:LTE (Set network search mode to 5GNR and 4GLTE only)
  • AT+QNWPREFCFG="mode_pref",NR5G (Set network search mode to 5GNR only)
  • AT+QNWPREFCFG="mode_pref",LTE (Set network search mode to 4GLTE only)
  • AT+QNWPREFCFG="nr5g_disable_mode" (Check to see if SA or NSA NR5G is disabled)
