NetworkManager missing wwan plugins in yocto project

narayanaswamym · January 30, 2021, 1:26pm

Hi Toradex,

I have included the NetworkManager and removed the ConnMan in yocto project by adding below lines in local.conf file.

Remove connman

MAGE_INSTALL_remove = ” connman”
IMAGE_INSTALL_remove = ” connman-client”
IMAGE_INSTALL_remove = ” connman-gnome”

Add NetworkManager

IMAGE_INSTALL_append = ” networkmanager ”
IMAGE_INSTALL_append = ” modemmanager”

I want to use NetworkManager and ModemManager for modem auto connection. But this is not happening because of missing wwan plug in NetworkManager.

Networkmanager-wwan plugin was missing in final image. Log messages are attached for your reference.

Please help on this.
Thank you

Hello,

Can you please post more details on software version you are using?

Also which modem are you trying to connect and interface you are using?

What are the sequence of steps you are following ?

Please also share the output of below commands

mmcli -m 0

nmcli c

check below article for more information

link text

It is for Torizon but same can be used if you have custom image with network manager and modemmanager.

Best Regards

Ritesh Kumar

1.Identifying the wwan interface is managed or not.
root@apalis-imx6:~# nmcli d

eth2 ethernet unavailable –
can0 can unmanaged –
can1 can unmanaged –
eth0 ethernet unmanaged –
usb0 ethernet unmanaged –

wwan0 wwan unmanaged –

root@apalis-imx6:~# nmcli -p

wwan0: unavailable
	"Quectel EC25"
	wwan (qmi_wwan), CA:94:10:9D:E4:CA, plugin missing, hw, mtu 1500

2.As you can see wwan0 is showing as unmanaged and plug-in is missing,so i have run a 
  command("nmcli dev set wwan0 managed yes") to set as managed one.
3.Now wwan interface is showing as unavailable.

What is the debug output you get whenever you connect your modem?

Hi @shreyas.

Thanks for the information, we are trying to reproduce the issue, allow us some time to get back to you

Hi @sahil.tx ,
Any update on this issue.
Thank you

ritesh.tx · March 15, 2021, 3:24am

Hi Narayanaswamyn,

This requires you to add support for modem for networkmanager as this is not by default enable from network manager recipe.

One can try to add same as below

through local.conf add below lines

PACKAGECONFIG_append_pn-networkmanager = " modemmanager ppp"

Alternatively create bbappend file for networkmanger recipe and patch your changes.
You can take reference from below recipe which is for our Torizon OS

github.com

toradex/meta-toradex-torizon/blob/master/recipes-connectivity/networkmanager/networkmanager_%.bbappend

FILESEXTRAPATHS:prepend := "${THISDIR}/${BPN}:"

# Depend on libedit as it has a more friendly license than readline (GPLv3)
