Sierra Wireless EM7565 LTE card supported?

[NKnusperer]

Hello, has someone successfully used a EM7565 LTE card?
There are two devices visible when creating a new Point-to-Point device: /dev/cuau0 and /dev/cuau1
Both of them are failing: The modem is not responding to "AT" at ModemCmd: label
Using "&F0E1Q0 +CMEE=2" as init string also has no observable effect.
usbconfig output:

Code: [Select]

ugen0.2: <Sierra Wireless, Incorporated EM7565-9> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

  bDescriptorType = 0x0001

Update:
It looks like that this device was just recently added to FreeBSD:

I created a issue for this: https://github.com/opnsense/src/issues/169

Try AT!greset as AT command (from GUI only !greset).
With sierra Mc7304 I had most success with this command.
Device should be cuaUx.0

[NKnusperer]

I get a "Connected" from cu but the session seems to be dead, nothing is ever retuned to any given command.

[tiermutter]

What are the commands you tried?

[NKnusperer]

"ATI" and "AT!IMAGE?".

Code: [Select]

# ls -a /dev/cu*
/dev/cuau0      /dev/cuau0.init /dev/cuau0.lock /dev/cuau1      /dev/cuau1.init /dev/cuau1.lockThere are only two devices which exist.

[tiermutter]

What says "AT" and "AT+CPIN?"?
Have you tried to reboot the sense?

[NKnusperer]

What says "AT" and "AT+CPIN?"?

Nothing, the session is just hanging.
I already rebooted multiple times.
Before installing it into the sense I upgraded to the latest firmware using Linux so I know the device itself is fine.

[tiermutter]

Hm, ok. I am not sure whether the device is recognized correctly or not.
It should be /dev/cuaU0.1 or /dev/cuaU0.2 out of 4 or 6, where one of them is the device that responds to AT (eg cu -l cuaU0.2).

[NKnusperer]

Which USBCOMP mode are you using?
Right now I'm using "1,3,10D" for QMI, might this be a problem?
As far as I understand neither QMI nor MBIM are supported by FreeBSD?
I also noticed that under Linux there are 3 serial interfaces exposed (ttyUSB0, 1 and 2) where 2 is the one which is responding to commands.

[tiermutter]

I don't know, sorry... I am using a external modem because I always had similar issues with the Mc7304 

[NKnusperer]

Now works with OPNsense 22.7.7.

[tiermutter]

Did you do soemthing special or just updated to the new version?
