Problems with HP lt4112 Gobi 4G Module

Thu Feb 18 15:50:40 UTC 2016

Hi,

I've sent a request to the Modemmanager/Networkmanager list because Modemnager wasn't able to establish a network connection. 

We did some tests and it seems that the problem is somewhere inside the qmi communication.

ModemManager fails when it tries to get the current ip settings, i can simulate the same with the qmicli

qmicli -d /dev/cdc-wdm0 --wds-get-current-settings

error: couldn't get current settings: QMI protocol error (15): 'OutOfCall'

[18 Feb 2016, 16:51:45] [Debug] Client released

Anyway starting the network works:

qmicli -d /dev/cdc-wdm0 --wds-start-network=web.vodafone.de --client-no-release-cid 
[/dev/cdc-wdm0] Network started
 Packet data handle: '1138179280'
[/dev/cdc-wdm0] Client ID not released:
 Service: 'wds'
 CID: '26'

After that I'am able to get an ip via dhcp
