Radxa phone with cellular module

Can you link such hw, epaper and emr to make a secondary screen for handwriting?

Or you’re just using your imagination? :blush:

Didn’t make my choice yet but I’ve read many good opinions on GL-iNet brand which are selling openwrt friendly LTE portable routers.
Looking at their MUDY product page, they propose either cat4 or cat6 versions of LTE modules (like the Quectel EP06).

Regarding lack of simcard slot it is expected in M-2 form-factor. You get it with the adapter (like m.2 USB adapter for instance) or on the board directly

I ended up ordering 2 devices. EM12-G and EG25-G.
Hope I can get them working, especially because the second one is used in pinephone.

If anybody interested in results
I got the modules and tried EG25-G
So I could make 4G internet to work without much problem. I can send SMS, initiate calls. I have not set it up to be able to talk over the phone. yet.
Also I have checked on ubuntu and armbian, havent checked on android yet.

I could initiate SMS, used 4G internet (as mentionned in feb 19 message), and cellular voice conversation. All phone functionality is working. I am on Armbian, also tried on Radxas Ubuntu.

But I need to make it accessible, in a more phonelike UI. May be I will prepare some tutorial. My end goal is to make tablet that works as phone and notebook.

I also installed Modem Manager GUI in Armbian to see what commands it has, but since I don’t have the card in the system, I can’t really see much… I found on aliexpress EG25-G with mini pcie interface, does it work in mini pcie interface or with an adapter? What firmware needs to be installed? I ordered an EG25-G board anyway.

You need a usb adapter for that one, rock5b does not have a slot you can put that in.
I have been searching for a card that I can directly put on the 5b, and which also has simcard slot. I could not find it. If you know of one that directly fits, I would like to learn from you.

Would this not work: https://www.mouser.com/ProductDetail/Soracom/4573326591584?qs=Y0Uzf4wQF3l6IoiWo78D0g%3D%3D ?

you see boards with sim and that eg25 and also see some riser to include both

only cannot get much of price some are expensive and some are cheap

#21

I finally received the modem, I’m running Armbian with kernel Linux rock-5b 5.10.110-media works with the sim in the card directly or in the adapter, but the modem manager gui stops, it only works with the gnome or xfce interface. What alternatives do I have for SMS and phone?
I mention that I also ordered an adapter for the M2 E with a SIM slot.
Thank you.

Well, you tell me :slight_smile:
I think it is good to reuse what is already developed, so I see using Android for phone functionality is the way to go. I could not make RIL for Android work yet.
My ideal result would be running Armbian on rock5b and Waydroid on top of it. But I need to build custom Waydroid image. So this is step by step plan

1 ) Make and Android image that runs on rock5b directly and makes phone calls
2 ) Apply the same changes to custom Waydroid image so that I can run rock5b as desktop (using armbian or rebornos) + as phone (using waydroid) at the same time.

#23

Can you please place link to the modem a d adapters you are mentioning?

#24

I wanted to use applications from Pinephone or is there PITalk, the problem is also with the sound transmitted via usb, the modem must be activated without having Modem manager Gui, I cannot try with sms,
do you have anything concrete? Adapter link: https://www.aliexpress.com/item/4001192388617.html?spm=a2g0o.order_list.order_list_main.5.21ef1802Sj19os

Is the adapter good? Please PM me how you managed to send sms and talk. That’s what you stated above (Aaaand the POC is ready. I had my first phone conversation through Radxa Rock5b).

#26

Did you order the adapter?

#27

I am using an adapter to USB.
