Openwrt with EM7455 connecting issue

[Michael pang]

Here is my netifd integration. This is the only one I created,nothing else.

config interface 'wwan'

       option device
  '/sys/devices/platform/soc/f1058000.usb/usb1/1-1/1-1.2/1-1.2.1'

       option proto    'modemmanager'

       option apn      'Broadband'
After rebooting, it is back to my first post. I have to run 3 commands but
still no connection. feel like I am getting close. but not sure what to do.
Thanks
1.device is disabled  run mmcli -e -m 0
2. no APN stored     run mmcli -m 0 --create-bearer="apn=Broadband"
3 establish connection mmcli -c -b 0
