if i remember correctly, the PLS63/83 has 2 enumerations, one is wwan,
the other one is qmi.
You should check how is your module enumerating with the command AT^SSRVSET.
Ok. I will check that out the response to that AT command.
With a newer kernel (6.1) I see the device enumerate as wwx00a0c6ee8cc0 (not
wwan0).
I think this is the new persistent naming scheme. I'm not used to it and not
sure how if effects my system, config, etc, but it's looking like it is a wwan
device.
# ifconfig -a
wwx00a0c6ee8cc0: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether 00:a0:c6:ee:8c:c0 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
The AT command produced an error. CME Error.
I was able to prevent the persistent name wwx00a0c6ee8cc0 and keeping wwan0 by
setting the command line arguments to include: net.ifnames=0
# ifconfig -a
wwan0: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether 00:a0:c6:ee:8c:c0 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
However, this still does not allow ModemManager to detect the Cinterion modem
as a WWAN device.
I.e. The device does not show up with: mmcli -L
My setup is now Debian 13 Trixie (testing) amd64, Linux kernel 6.12.12, modem
connected via USB, ModemManager 1.22.0, NetworkManager 1.50.2.
How do I get ModemManager to detect the Cinterion PLS63 modem?
Some debug.
