I am using a Telit LM940 module to have LTE connection.
My problem is that I currently have two modules with the same characteristics but one of them doesn´t work properly. If I try to establish connection:
root@OpenWrt:/# uqmi -d /dev/cdc-wdm0 --start-network --apn internet --ke ep-client-id wds "Call failed"
And the connection state:
root@OpenWrt:/# uqmi -d /dev/cdc-wdm0 --get-current-settings "Out of call"
I already know that the Telit LM940 only supports Raw-IP so I changed qmi_wwan driver to use it and the option autoconnect is disabled.
I followed the same steps for both modems and in the other one everything works without problems, so I am starting to think that it is a matter related to the hardware.
