# 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.
