Description

Cellular modem control and connectivity

Optional libraries libmbim and libqmi are available. Your modem may require additional kernel modules and/or the usb-modeswitch package.

Usage

Once installed, you can configure the 2G/3G/4G modem connections directly in /etc/config/network as in the following example:

config interface 'broadband'
    option device      '/sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.2/1-1.2.1'
    option proto       'modemmanager'
    option apn         'ac.vodafone.es'
    option allowedauth 'pap chap'
    option username    'vodafone'
    option password    'vodafone'
    option pincode     '7423'
    option iptype      'ipv4'
    option plmn        '214001'
    option lowpower    '1'
    option signalrate  '30'
    option allow_roaming '1'
    option force_connection '1'
    option init_epsbearer '<none|default|custom>'

Only 'device' and 'proto' are mandatory options, the remaining ones are all optional.

The 'allowedauth' option allows limiting the list of authentication protocols. It is given as a space-separated list of values, including any of the following: 'pap', 'chap', 'mschap', 'mschapv2' or 'eap'. It will default to allowing all protocols.

The 'iptype' option supports any of these values: 'ipv4', 'ipv6' or 'ipv4v6'. It will default to 'ipv4' if not given.

The 'plmn' option allows to set the network operator MCCMNC.

The 'signalrate' option set's the signal refresh rate (in seconds) for the device. You can call signal info with command: mmcli -m 0 --signal-get

The 'force_connection' option is designed to ensure that the modem automatically attempts to reconnect regardless of any errors encountered during the connection process.

If there is no Circuit switch network available, then an initial EPS bearer must be set, so this could be used during the network registration process in 4G and 5G network. For this resaon a new configuration option 'init_epsbearer' was added, which could have the following values.

  • none: Do not set an initial EPS bearer (default)
  • default: Use the configuration option 'apn', 'iptype', 'allowedauth', 'username' and 'password' for setting the initial EPS bearer. These are the same options as when establishing a connection.
  • custom: This could be used to use diffrent options when establishing a connection. The options are prefixed with an 'init'. So we have the following options 'init_apn', 'init_iptype', 'init_allowedauth', 'init_username' and 'init_password' for setting the initial EPS bearer.
