Hello Alexander and people in the list, Let me provide some additional information and new test log messages.
The problem I reported is improved one setp. Originally it was like:
root at LEDE:~# mmcli -L
error: couldn't create manager: Timeout was reached
Now it is like:
root@LEDE:~# mmcli -L
No modems were found
I had to enable "dbus-utils" under "Utilities" of openwrt make menuconfig.
So it seems that now mmcli talks with ModemManager at last. The problem now
belongs to ModemManager not in the mmcli.
And I created the rule file you provided:
# vim /lib/udev/rules.d/78-mm-custom.rules to fit to my modem:
ACTION!="add|change|move", GOTO="mm_custom_end"
DEVPATH=="/sys/devices/platform/1a0c0000.usb/usb2/2-1",
ENV{ID_MM_TTY_BAUDRATE}="115200"
DEVPATH=="/sys/devices/platform/1a0c0000.usb/usb2/2-1",
ENV{ID_MM_TTY_FLOW_CONTROL}="xon-xoff"
LABEL="mm_custom_end"
I wonder if these rule files are supposed to be provided from the modem
provider. In my case, it is Hucom wireless.
Can I ask them to provide this file?
My modem is supposed to operate with this configs:
device : /dev/ttyUSB1
baudrate : 115200,
parity : none,
data : 8,
stop : 1,
flow : xon_xoff
And I added config section like shown below in the /etc/config/network:
config interface 'broadband'
option device '/sys/devices/platform/1a0c0000.usb/usb2/2-1'
option proto 'modemmanager'
option apn '5g-internet.sktelecom.com'
option username ''
option password ''
option pincode ''
option lowpower '1'
I don't know the username and password, but maybe it wouldn't be needed at
all. the pincode... I have no idea with this..
And also I added "--debug" in the start script /etc/rc.d/S70modemmanager:
procd_set_param command /usr/sbin/ModemManager --debug
And with these conditions, I rebooted my linux box and after the reboot is
done, maybe 5 minutes later I captured log message:
logread > logread_last.log
And I attached it in this email. Please find the log message and see it
through.
And you wanted to know what modem is mine:
The modem is HUCOM HM-900

Do I miss anything?
F.Y.I. the modemmanager was not included in my OpenWRT source code. I
copied it from https://github.com/openwrt/packages and I just enabled it
via openwrt make menuconfig.
Thank you very much in advance!
