RC7620 does not connect in QMI Mode

[JFTWIT]

Hello,
Since updating the RC7620 modem to v9.6.1, it has been impossible to establish a QMI connection with a SIM from the MEO operator. No problem with an ORANGE SIM.
In France the MEO operator does Roaming.

Here is the QMI error in the logs:

Thank you for your help

Can it establish data connection by AT!SCACT or MBPL connection manager app?

Example on establishing data connection by AT!SCACT via MBPL R20 driver

Here is an example to establish data connection by AT!SCACT via MBPL R20 driver: Module: WP7609 FW: R13 MBPL: R20 PC Environment: Ubuntu 18 need to install the MBPL R20 driver for qmi_wwan and qcserial (MBPL_Drivers_USB_R20_ENG1-src.tar.gz) avoid the Ubuntu changing the network name: ln -s /dev/null /etc/systemd/network/99-default.link sudo apt-get install libqmi-utils sudo apt-get install udhcpc now insert the USB to PC sudo chmod 777 /sys/class/net/wwan0/qmi/raw_ip …

Btw, do you mean it works in release 9 or earlier firmware?

This is not possible because the modem is not in a PC but in an embedded system.

Btw, do you mean it works in release 9 or earlier firmware?
with firmware it worked
with firmware it does not work
but with SIM ORANGE works with both firmware.

do you have another idea ?

AT!SCACT or MBPL connection manager app can also be run in embedded system

Next, i don’t see you specify the authentication type like PAP or CHAP:

BTW, is that all roaming sim having problem in release 9.6.1?
Does your orange SIM need username password authentication?

Lastly, as it says there is authentication error, I wonder if you need to set AT$QCPDPP

AT$QCPDPP command - Allowed password characters

Hello, The AirPrime MC/SL-Series - Extended AT Command Reference document mentions the AT$QCPDPP command (used as AT$QCPDPP=, <auth_type>, , ), which allows setting PAP/CHAP authentication parameters. Does anyone know which characters are allowed in the password parameter? I can not seem to find this information anywhere. Basically I’d like to know if any 8-bit extended ASCII character allowed, or just a subset? Which characters have special meaning, such as the quotation mark ("), and can the…

Next, i don’t see you specify the authentication type like PAP or CHAP:

It’s in the configuration file used to launch the QMI connection
example:

@jyijyi

No. The same SIM in an RC7620-1 modem with firmware 9.6.1 works

@jyijyi

Does your orange SIM need username password authentication?

Yes, but it’s orange / orange

@jyijyi

Lastly, as it says there is authentication error, I wonder if you need to set AT$QCPDPP

I didn’t know about this order.
I’m going to do some tests

[jyijyi]

It is quite strange that same firmware and carrier PRI works in RC7620-1

Is it failed in all RC7620?

You might also need to try AT!SCACT or MBPL connection manager app to see if there is any improvement
