Using thuraya so-2510 as GmPRS/GPRS modem

Tomas20 · September 17, 2024, 11:43pm

Hello
Im new with openwrt and would like to use my thuraya so-2510 satellite phone with openwrt to get data/internet connection
I was trying to configure the device with my openwrt router
Read some pages and watched some videos trying to learn how to identify and configure the satellite phonee with my router so i can make gprs/gmprs connection
First it was showing as fast speed usb device

Installed some opkg packages and i found out that (kmod-usb-acm) package is the only package that connected thuraya so-2510 device was responded now it's showing in system log as CDC-ACM device (ttyacm0) also it's showing in interface devices list

Now im not sure if that is enough and it should be completely identified and need no more drivers

If this means it's ready to make connection im still have problem to make the connection configuration ,what protocol should i use and where to enter the required configurations such as (dial number.....etc)

Any one have experience with such a device before

Router used : tp-link mr3020/hardware version 3.20
Openwrt version: openwrt-23.05.4-ramips-mt76x8-tplink_tl-mr3020-v3-squashfs-sysupgrade.bin

I am not an expert but I believe you can try package: modemmanager

Show the output of cat /sys/kernel/debug/usb/devices

APN name is GET , rest looks like AI translator went rogue down to text making no sense.

Talk to modem using minicom and modem response correctly

brada4 · September 23, 2024, 3:50am

It is "get" but in CAPS.
And disable ip6 if it disconnects.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

cat /etc/config/network

all this info, yet you failed to post what was requested a day ago...

Tomas20 · September 23, 2024, 12:20pm

I will change the APN to capital letters (GET)

And thank you to warning me brada about mac/ip/passwords and personal data

Thats not my thing, thats collaborator template, so thanks goes to site admins/mods who authored it

brada4 · September 23, 2024, 2:50pm

You have rather limited flash memory, like insufficient to utilize phone as WAN backup, so you will need to click wwan off and mobile on every time you need.

Detailed info:
https://openwrt.org/docs/guide-user/network/wan/wwan/3gdongle

option ipv6 '0' seems needed if error still persists after changing APN.

Basic theory of operation is that you "dial" the packet modem and it handles the cellular network providing you packets via ppp protocol.
If the parameters are not correct for packet network (the get/GET) then it chokes later down the road after "dialling" modem itself. Like 1s later just disconnects.

EDIT: the step further will be to add pppd debug messages and adapt system so it can capture them without crashing filling small memory.

brada4 · September 24, 2024, 3:20am

https://openwrt.org/docs/guide-user/network/wan/wan_interface_protocols#protocol_ppp_ppp_over_modem

option pppd_options 'debug'

EDIT: corrected config line.

brada4 · September 24, 2024, 8:45pm

LCP debug messages show very detailed ppp protocol trace. Like other side rejecting compression etc.

brada4 · September 25, 2024, 10:53am

No, there follows ppp connection negotiation.

brada4 · September 26, 2024, 3:25am

Do you have data service?

Tomas20 · September 26, 2024, 7:04am

If u mean data service on the sim card (internet service) yes i do have also i test connection on windows xp and it works fine

brada4 · September 26, 2024, 7:39am

The trace up to pppd start looks normal. Can you enable windows ppp trace and compare and try to replicate ppp connection features?
Maybe provider knows? The UNIX pppd is like decades old, you are certainly not first to try it.

Thuraya have customized openwrt firmware for tp-link mr3040 named xt hotspot, is it possible to modify it to work with mr3020 or extract the settings to use it?

openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-sysupgrade.bin

Or at least is there any way to install the firmware on virtual machine or somthing like this to extract the settings

Here's the link from official website showing the firmware
