Puli - How to change (cellular) network provider?

EddieA · 2022-09-08T16:35:02.107Z

For my sim, the provider gave me the value to set in APN under Manual Setup.

I have the APN settings.
They are the same everywhere, in any country.
They do not change according to available local network providers.

But the local network providers change by area.

And I need to be able to define which local provider the Pulli should connect to.

@alzhao
Is there no way to chose one specific network provider with Puli? Instead of having the device chose one automatically?
As you can do with an iPhone when disabling automatic choice (see screenshot).

I have never done that. I can send you a manual of AT command to explore.

Have you already figured out how to do it, I have the same problem?!

spamatiki · 2023-12-20T10:15:49.104Z

Never figured it out.
It just „does not work“
Really annoying

XXXLA · 2023-12-20T14:57:23.217Z

Do you want to tell me how to do it?

admon · 2023-12-20T15:37:32.387Z

I’ll try to play around with the AT commands, but there is something I don’t understand:

After my SIM connected I am trying to get my current network:
AT+COPS?
which results in
+COPS: 0,0,"Telekom.de heyah",7

That’s great.

But when I do
AT+COPS=?
to list all available networks, the modem dies. GUI tells me the USB modem is unavailable and the “Internet” LED on the front turns off. Ping is working without problem - so something is odd here.

After a reboot everything is fine again. The same happens when I send AT-COPS=? by using socat /dev/ttyUSB2

@lizh can you have a look?

lizh · 2023-12-21T14:13:25.577Z

What model of device?

If the AT instruction is not supported, the AT instruction interface is blocked.
You won’t be able to get information through the AT command.The interface displayed on the web interface also disappears.

lizh:

What model of device?

XE3000

lizh:

If the AT instruction is not supported, the AT instruction interface is blocked.

How to revive it again?

lizh · 2023-12-21T14:40:48.830Z

XE3000 should use /dev/mhi_DUN.

Please help exec :

AT+QCFG=“data_interface”

admon · 2023-12-22T19:21:23.119Z

Not sure if I’m smarter than before now:

AT+QCFG="data_interface"
+QCFG: "data_interface",1,0

OK

and the modem is gone again.

Edit: But just for a few seconds, than it comes back. Is this the command to revive it?

lizh · 2023-12-25T08:34:07.294Z

No, This is to check the modem communication mode.

I need a remote debug.Could you share with cloud platform:‘gl.inet_support’.

admon · 2023-12-26T12:37:06.798Z

Device shared. Maybe you will even find the issue why the cellular GUI is gone…

lizh · 2023-12-27T07:15:53.353Z

I need the known the Mac of the device,otherwise, I don’t know what device it is.Please send to me via Message.

admon · 2023-12-27T07:55:21.524Z

Sorry, sent it to you.

lizh · 2023-12-27T11:45:36.028Z

Hi admon:

‘AT+COPS=?’ is a long response instruction.But web pages do not support long response instructions.

It will block the AT instruction channel so that it cannot detect the modem.

It needs to be executed with the following instructions:
gl_modem -B 0001:01:00.0 SAT sp AT+COPS=?

Yey, that is something I can work with!

I'm getting the same 3 providers listet in my location: Vodafone, Telekom and O2. But the main question still remains: how can I switch from currently Vodafone to let's say Telekom? This is something really essential if we talk about travel router. In my iphone I have the setting: automatic provider selection. If this is selected, the iphone picks the best possible connection that fits to my vodafone simcard. But if Vodafone connectivity sucks in my location, I can unselect "automatic provider selection" and I get a list as shown above where I can select the one that has highest signal quality. Again..... this is essential when travelling.
Initially I thought this was done by selecting profiles...... but this is not working and has no functionality in my X3000
