# OpenWrt ModemManager
## 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 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
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.
