Latest firmware for PinePhone modem!

[Anna]

may not be best place, but i put it here.

those mobile data disconnects, i possibly found key issue to avoid them. edit file "/usr/lib/udev/rules.d/80-modem-eg25.rules" and change ATTR{power/control}="auto" into ATTR{power/control}="on". tested on manjaro arm linux. most likely will have side effects like wasting battery.

(actually advice came from matrix channel for modem disappearings.)

That did not work on my phone, I'm afraid. (Bookworm with all updates.)

Still same behaviour: Usually mobile connection after a restart and no connection after some time (or after certain unknown events).

maybe, you should try other distributions, like postmarketos, manjaro or archlinux.

it has been few months when i used mobian but it heated alot, run unreliably on sdcard and constant mobile disconnects. however, i haven't tested recently. manjaro seems to be more reliable but not problem-free.

i tested archlinux/sxmo shortly, weird user interface and not for ordinary users, it seems to be quite stable though.

I have to take that back: It DOES work!

Sorry about my initial, wrong assessment, I don't know what went wrong. But I in my despair I tried it again and now there are hardly any modem crashes.

That's more than great, because now my pinephone has become actually usable!

Thank you, zetabeta!

Glad to hear you got it working, finally.

However, to be clear, which one (or more?) of the several things zetabeta mentioned (udev rule, various distros, etc.) was the one that ended up working for you?

In Mobian, I opened the file

/usr/lib/udev/rules.d/80-modem-eg25.rules

and the changed the first line from

ATTR{power/control}="auto"

into

ATTR{power/control}="on"

That did the trick. Crashes are down from several a day to practically none.

You use firmware custom or stock?

stock, https://github.com/Biktorgj/quectel_eg25...004.30.004 .

I failed to flash the firmware from Mobian bookwork (up-to-date) running from SD card.
I booted to Plasma Mobile on eMMC, mounted the SD card and successfully flashed the version above.

mmcli -m any --command='AT+QGMR'
EG25GGBR07A08M2G_30.004.30.004

Here is the list of VoLTE profiles in that version:

Well, I guess I have to qualify my earlier praise of ATTR{power/control}="on" a little:

It does prevent crashes, but it also drains the battery quite a bit.

[Juergen]

I use the open modem firmware from Biktor (0.61) and just tested "mobian-pinephone-phosh-20220327.img.gz".
At incoming calls the phone does not ring reliably.
In PMOS (edge) it works perfectly.
(Braveheart Edition 1.1.)

[zetabeta]

this is my recommendation, not the devs recommendation.

if you use stock firmware for eg25-g chip/modem, i recommend 30.004.30.004 version instead of 01.002.01.002. https://github.com/Biktorgj/quectel_eg25...004.30.004

(partially) open source firmware is different. what i'm saying is i don't have view which should be preferred, open source of stock. if it is stock, i recommend 30.004.30.004.

Not quite as good a result here.   

I've got the Biktor modem firmware and PMOS edge, too, but still don't have reliable incoming call service. Playing around with other distros, too, but so far no luck.  USA, AT&T MVNO. And of course the problem is I don't know if I'm not getting calls because no one's calling or I'm not getting calls because the modem has decided to take a nap.  At least until my wife comes in and demands to know why my nerd phone isn't working and she gets my voicemail. Domestic tranquility may require me to get a flip phone or something.   (Still better than Android, though.)

If anyone's got any good suggestions as to how to periodically poke the modem with a pointy stick so it doesn't doze off, I'm all ears.

Did you follow Biktorgj' recommendation about the udev rule? Here is a link for the OG Pinephone.

Basically you need to edit /usr/lib/udev/rules.d/80-modem-eg25.rules. Change "auto" to "on" in the 1st line and reboot.
