Pinephone Pro LTE issue
#1
Bug 
Hey pinefriends! This is my first post. 


I got my Pinephone Pro Explorer Edition in the mail a couple days ago. I've installed Tow-Boot, Mobian Phosh, and the 0.6.8 firmware update for the modem. I did this via the 'firmware' app from the software center. Currently I have an AT&T SIM card in the phone but plan to switch to Google-Fi before long. Almost every time the screen turns off I completely loose LTE such that the mobile connection section of the settings app disappears. It also happens, much more rarely, in the middle of actively using the phone. It's happened while writing a text message, while browsing on firefox, and even just while scrolling through the apps section. It does not loose it's connection to WiFi when this happens, so I know it's not the whole modem shutting off. Before updating the EG25 firmware I had to reboot the phone each time this happened. Now it consistently reappears when I enter the network settings and start the process of creating a new wired connection. 

  https://forum.pine64.org/showthread.php?tid=14342  --this thread gave me the idea to try systemctl edit --full ModemManager to change --test-quick-suspend-resume to --test-no-suspend-resume

I didn't see that line or anything like it in the file that was opened. 

Please if anyone knows why this is happening or has advice on how to fix it that would be lovely. It's really the main thing standing between me and PPP as a daily driver.

Have you tried this:



Quote:
  1. Stop the modem from disappearing on suspend
  • Edit
    Code:
    /usr/lib/udev/rules.d/80-modem-eg25.rules
  • Look at the last line:
    Code:
    ACTION=="add", SUBSYSTEM=="usb",
    DRIVERS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="2c7c",
    ATTRS{idProduct}=="0125", ATTR{power/persist}="0"
  • And change persist to 1:
    Code:
    ACTION=="add", SUBSYSTEM=="usb",
    DRIVERS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="2c7c",
    ATTRS{idProduct}=="0125", ATTR{power/persist}="1"
  • Edit
    Code:
    /usr/share/eg25-manager/pine64,pinephone-pro.toml
    and make sure
    Code:
    monitor_udev
    is set to
    Code:
    false

Actually latest eg25.rules has 4 goto statements in first 4 lines. Make sure line 3 is DEVICES (plural), not DEVICE. You shouldn´t need the other changes.
