Cosmo Communicator - Linux / Re: How to crosscompile the Cosmo Linux kernel

« on: July 29, 2020, 12:39:03 pm »

Have you been able to build .deb packages (want to have kernel headers as well in order to install some drivers and this is much easier to manage with .deb). I get some missing UAPI file ../fpsgo.h error. Managed to compile .deb a long time ago however I did not note down all of the steps I took.

Cosmo Communicator - Linux / GSM-calls?

« on: April 15, 2020, 02:36:55 pm »

Which /dev/radio interface did you use? I've tried a few so far with no luck. I'm just using minicom though so not sure if I'm doing it wrong!

There the multiple different file discriptors each correspond to the some function for the 2 different UEs? (Is this modem true multi-UE or Mux'ed?) in the cosmo (1 per modem). the /dev/radio/acti1 is the first modem is atci1 and the second acti2. I have tried to use minicom as well but there seams to be some issue with the terminal-setup on the cosmo. Instead I used the echo and cat in two different terminals.

A few different references https://comsecuris.com/blog/posts/path_of_least_resistance/ and https://github.com/CellularPrivacy/Android-...ctor/issues/199

Also to answer milbry's question: I have been busy with my regular work and there have limited time to progress/investigate, however, I did do a dump of the modem setup process in android using logcat -b radio to understand how the process of the modem setup occurs as this basically to my understanding need be replicated by the RIL driver/plugin for ofono (the android-mediatek RIL is still user when booting under linux). From this it is clear that the rild-oem (different for previous media-tek approaches, see https://github.com/rilmodem/ofono) is used for some kind of diagnostic/configuration under android and that the ccmni1 and ccmni2 are the actual ppp data interfaces that are used in android. I have not filtered the dump for private information yet and will therefore not post it.

Hi to all

From the telegram group, Cosmo is missing a ofono plugin. So Wont work for now. Hopefully soon.

Well, installed Dialer app, but right, " no network" error. Setting up a broadband-connection in the networkmanager application didnt help either ... any new idea?
Thanks for your advice!

After reading up on android cellular stuff (apparently not the same as interfacing with standalone modems) as well as the reply from milbry I managed to find and configure the modem using good old fashioned AT command through  /dev/radio interfaces and even sending and SMS. Now I am trying to see if I can get it working through ofono, however my experience with ofono, Android RIL  etc. is limited.

Are you using v20 or v21 firmware,  right ?
In v19, I can't see my sim card.
Thanks

I am running v21.

Hi,

Have you been able to use the modem in Linux? I have not had any luck even finding it using tools like modem-manager etc.

With regards to applications there should be an ubuntu-phone application called dialer-app.

Cosmo Communicator - Hardware / Observations regarding the mechanical construction

« on: December 16, 2019, 08:18:51 am »

Hi All.

Just got my Cosmo last week and overall I find it to be good device with solid mechanical construction. However, I do have a couple of observations that I like to discuss and hear whether other user have the same experience.

1) keyboard-wobble/lack of stabilization. I have found the keys to be quite wobbly is this also the case for other people as well? (not that this is big problem it just make harder to get use to the keyboard)
2) hinge not closing completely if the amount of force applied is low. In some cases where I close the lid gently I have to manually press on the lid to completely close it.

Regards.
