Hi,

I am trying to get a Alcatel IK41 running on a Raspberry. The dongle is described as a USB-part to be controlled via AT-comands in order to take full control about the LTE-connection.

I intend to use it in a stand-alone homatic-environment for a time to time transfer of log-events over the internet with a LTE connection.

Here is the environment: RockPi4B, armbian/debian bullseye. On a clean new and updated installation of today I got the following information after inserting the Alcatel-Stick:

A strange message occurs after apt install wvdial:

What about " http://ik41.home/index.html" ??

Thereafter I installed usb-modeswitch and usb-modeswitch-data and cretated a file
/etc/usb_modeswitch.d/1bbb:f000

As this didnt help I configured according the following forum entry:

What I have done:
- disable the automatic mode switch at boot (DisableSwitching=1 in /etc/usb_modeswitch.conf)
- create a script to be executed at boot, for manual usb mode switching
Script content:
$ cat ~/switch_to_modem.sh
#!/bin/sh
usb_modeswitch -v 0x1bbb -p 0xf000 -V 0x1bbb -P 0x0195 -K

Line to add in /etc/rc.local (note: before exit 0):
sudo /home/pi/switch_to_modem.sh
Of course one could also avoid creating the script file, and just add its content directly into /etc/rc.local. I prefer to have the script at hand.

The outcome:

Does anyone have an idea how can I solve my problem, or is the alcatel ik4 not suitable for my project??

Thanks in advance

I'm having this issue as well. I got one of these sticks from eBay because it was LTE and didn't have wifi built in.

Im trying to use smstools. So I need this device to come up as /dev/ttyUSBx.

I'm no stranger to linux, and know my way around. However I've never messed with WWAN USB devices in this manner. I too get only RNDIS + storage devices. I've tried things in this thread as well as other places on the net and so far I cannot get this device to "revert" (???) to "serial mode". I actually have no use for RNDIS / ethernet / IP connectivity. I simply want serial to send SMS.

Would love to know the magic to this (if there is). Besides that - I'd love to know of a USB stick that supports at least 4G in the USA that does work for SMS (easily).

Thanks.

Sorry to self reply - but I see this thread:

https://draisberghof.de/usb_modeswitch/ ... php?t=2577

And the last message is saying that this device is NDIS/storage only (firmware limitation). So no serial at all. If that's the case - that would explain why it's such a nightmare to try to get this thing to expose a serial port.

So my solution was to return the IK41 and get a Huawei UMG366 (Tmobile branded). This presents the USB serial, sg/cdrom, and WWAN (of which for my purpose (smstools)) I only need the USB serial).

I'm using this in the USA with a Tello SIM (TMO MVNO). Working well so far.

I have read the explanations in this topic, they have solved my doubts

The Alcatel IK4 is a USB dongle that can be used to connect to the internet via LTE. To use it, you will need to install the USB-mode switch and wvdial packages. You will also need to create a configuration file for usb-modeswitch.
