Better OpenWRT support

Hi.

I’m trying to improve OpenWRT support. If others have modems working successfully (I have two RM520N-GL’s that don’t yet work), I’m trying to collect:

  1. the .config section necessary to support QMI mode
  2. the .config section necessary to support MBIM mode
  3. tweaks to use USB or mPCI-e modes in that .config
  4. the /etc/config/network section to use a 5G or 4G/LTE carrier for the ISP in QMI mode
  5. same but for MBIM mode
  6. any useful tips/tricks that could be thrown into expect scripts to gather debugging/troubleshooting information

Please reply here or send them to me via email. I’m pprindeville on GitHub.

I have a card with the 302 firmware and a T-Mobile Business 5G SIM and see:

and it just loops with the following network config:

        option device '/dev/cdc-wdm0'
        option apn 'fast.t-mobile.com'

        option pdptype 'ipv4v6'
        option plmn '310260'
        option modes '5gnr,lte,umts'
        option dhcp '1'
        option autoconnect '1'
        option debug '1'

Once again, forget about OpenWrt, QMI, MBIM, etc. for a while. Use a dumb terminal to troubleshoot your registration issue.
