[Update: Mar 25th] Testing Quectel EM12-G WWAN 4G Modem on Librem 5

Why you ask?: That is the point of open hardware, and open software to break things and in the process make things better for others. Future plans are to test this with kernel 5.19.0 on Ubuntu using a M.2 to USB3 adapter and see if there is any difference in functionality that may point to required kernel updates required on pureos10, quectel provides the kernel update information as referenced below, so maybe kernel updates also need to be manually applied.

Modem Configuration:
sudo mmcli -m any | grep -v 'imei\ |Numbers\ |equipment id\ |device id: ' >>imei.txt

  • Mobile Data = on, Data Roaming = on
  • AWESIM APN provider NXTGENPHONE
  • EM12-G with latest available Quectel firmware loaded (as of March 2023)
  • Expected Modem Serial Configuration:

/dev/ttyUSB0 - DM
/dev/ttyUSB1 - For GPS NMEA message output
/dev/ttyUSB2 - For AT command communication
/dev/ttyUSB3 - For PPP connection or AT command communication

Functionality (as advertised, not all tested):

  • CAT 12 modem
  • compatible with AT&T, T-Mobile ~‘all’ LTE bands in the US (unsure)
  • Physical size equivalent to BM818 modem (yes, tested)
  • M.2 slot same number antenna connections as BM818 modem (yes, tested)
  • Signal strength appears to be comparable to BM818 modem (unsure)

Things Attempted:

  1. modem installed
  2. updated 85 pm rules (vendor, prodid, power/autosuspend_delay_ms:3000ms, power/control:auto, power/wakeup:enabled, power/persist:0, avoid_reset_quirk:1)
  3. updated 77 mm quectel rules (vendor, prodid, port type)
  4. disabled usbguard (usbguard.service wasn’t running even before that)
  5. attempt to install arm64 modem manager 1.20 .deb but has dependency issues
  6. sudo socat - /dev/ttyUSB3,crnl allows AT command and favorable responses (SIM detected etc)
  7. AT+QNWINFO +QNWINFO: "FDD LTE", "310260", "LTE BAND 2", 975, OK
  8. enabled Modem, ModemManager & NetworkManager DEBUG and dmesg | grep -i ttyusb3, or wwan, or modem does not show anything useful
  9. fixed the now driver issue from lsusb load option driver echo "2c7c 0512" > /sys/bus/usb-serial/drivers/option1/new_id
  10. unbind other interfaces sudo bash -c echo '"1-1.2:1.8" > /sys/bus/usb/drivers/option/unbind'
  11. unbind other interfaces sudo bash -c echo "'1-1.2:1.9" > /sys/bus/usb/drivers/option/unbind'
  12. check if all supported devices are now listed, and it appears they are:
    `ls -la /sys/bus/usb/drivers/option/’

  1. use HKS to restart modem, wait and talk to modem sudo picocom -b 9600 /dev/ttyUSB2 with AT commands “OK”
  2. changed baud rate from Quectel default 115200 to 57600 which the modemmanager is using as default based on some blog trouble shooting i found out using AT+IPR=57600 command

Steps to Repeat the Following Error Log:

  1. turn modem off
  2. turn modem on wait for 4G bars to show in UI
  3. toggle mobile data
  4. send message, or try to place call

Observations, Issues to be resolved:

  1. modem does not stay connected to 4G for very long and drops out shortly after reboot
  2. was able to send one message, and receive messages when the modem is up, but no data connection
  3. toggling HKS for modem does not bring the modem back always
  4. only symbol on phone that shows when modem drops out is the no data connection (there is no 2G, 5G or any connection bars shown)
  5. modem showed as registered with correct phone # in mobile data settings and with signal strength shown
  6. after HKS toggle, and scanning for the modem with mmcli -S, and then executing mmcli -L sometimes brings the modem back with /org/freedesktop/ModemManager1/Modem/2 [Quectel] EM12, but only for a while until it drops out again
  7. general ability to use mmcli to communicate with the modem when it is up e.g. mmcli -m 6 --enable results in successfully enabled the modem
  8. I read somewhere that it may take 2min for the modem to become fully functional, and interestingly exactly about 2minutes after say waking from suspend, or restarting the phone the modem 4G drops from the UI, while initially it is shown
  9. In addition sudo systemctl restart NetworkManager ModemManager is the only other way to bring the modem back temporarily (other than suspend/wake, and reboot).
  10. Quectel support and documentation appear to be much better than Broadmobi.

Help Needed:
Those of you guys and gals that have experimented with other modems and got them working Please add input here, or I will for you:

  1. e.g. purism does this modem need to be added to your config to be supported by T-Mobile (whitelist?)… answered my own question using the T Mobile IMEI compatibility checker:
    Screenshot from 2023-03-08 13-44-29

  2. e.g. purism the modem almost works for SMS, what needs to change to allow audio to be processed, could configuration files be made more generic and not modem specific to plumb or route modem audio (i see audio configuration files for BM818 but not sure how to change them)?..

  3. e.g. the modemmanager modem configuration files include Quectel but not he EM12-G modem, where would i need to file a report to request updates to these files?..

  4. to unbind other interfaces permanently you have to add this to a startup scrip, but how?

So doesn’t seem to be reliable enough?

Did you try, you know, an actual voice call?

Annoying that the specification says “VoLTE (Optional)”. I think it means that VoLTE should work but …

The “-G” in the model number should mean “global” i.e. compatible with “all” bands in “all” countries - or close to it. The actual list of LTE bands is not literally “all bands” but it may be good enough.

Not usable right now or reliable, but might just be a setting somewhere. Typically when I try to send messages (chatty), or do a voice call (calls) it simply drops out if previously connected with 4G symbol and say 4bars. Maybe that is pointing at the bus not providing it with enough power? Executing lsusb it states somewhere max power ~500mA i think. Looking at the Quectel spec sheet it doesn’t give the actual max power usage, only idle and sleep power usage, when it is up i have been wittling down the options and am switching everything off that isn’t needed (such as GPS data collection etc., to maybe reduce power usage when running).

As this is an M.2 device, it may be more complicated than that.

not really since it is hooked up to the USB as ttylUSB3 pretty sure.

The point is that the M.2 connector has 75 pins. In the case of the modem, it is B-keyed, which means that pins 12…19 are notched (and at a quick look, all the remaining pins are connected, albeit many are grounded). Unless you have studied the schematics, and the modem’s documentation, and have the expertise to understand them (Disclaimer: I don’t), you don’t really get all the information about the power requirements.

Yes, it is true that (in this specific configuration) a small number of pins on the connector, presumably 4, give a conventional USB interface.

ok gotcha, i did not check and was just crossing my fingers, i can communicate with the modem, and it is possible there is an issue with the hardware configuration since the modem does not work properly - but my feeling at least is that it should be working based on what i have been seeing, since it briefly and actually connects to 4G…

I think I am right in saying that the actual Librem 5 software doesn’t typically use AT commands to communicate with the modem, but that’s what you are doing, right? The ttyUSB device that you are using will respond normally to AT commands but I think the software will use QMI, which will be a different ttyUSB device (and I suspect is not intended for use by humans).

Note also that audio is a whole extra ball game. That M.2 configuration sets aside pins for audio to come in as PCM, separately from any control commands. (I would have to check the schematics to find out where it is coming from.) And then there are questions as to how the modem’s audio source is configured, if configuration is needed.

Tested the same EM12-G Quectel Modem with the following.

Functionality:

  • Connected to desktop computer via usb cable and tried both USB-B, and USB-C
  • it just works, while the signal is only 9% it immediately recognizes the modem and i am writing this post over the Quectel EM12-G, which excludes the possibility that the modem did not work when trying it in the L5
  • There are three antenna ports on the modem, one is for GPS, so its possible i connected the 5G antenna to the GPS port not the 5G port, I will switch it over and see if that improves anything
  • Data connection works and it lets me browse the internet, with VPN and there is not ipv4, 6 IP leakage

Things Tried:

  • Tried Gnome-Calls but no cigar it just seems to dial but no ringing sound and will not connect, plus on my desktop ubuntu the microphone in the external monitor isn’t properly recognized and its way too quiet.
  • Tried to install chatty sudo apt install chatty to my surprise its not in the Ubuntu package repository any longer, not sure why since it is a XMPP, and Matrix chat client?? Getting the following error when installing from git:

dpkg: dependency problems prevent configuration of chatty-dbgsym:
chatty-dbgsym depends on chatty (= 0.7.2+librem5ci82984.0e6da9f0); however:
Package chatty is not configured yet

So that leaves the question if it works over USB on a desktop running stock linux and stock kernel, and the modem is supported since kernel ~5.15 around, why does it not work with the L5?

Observations, Issues to be resolved:

  • Fix antenna connection reception issue
  • Get chatty, or gnome-calls to work
