LTE modem to D410c, no Mobile networks menu



I wanna test an USB typed LTE modem to D410c,
but Android Lollipop does not have ‘Mobile Networks’ setting menu.

Any ideas about this ?



If you want to integrate this as a standard modem (AT commands…), You will have to integrate or implement the radio hal (cf Note that Android provides a basic vendor RIL with minimum feature set (hardware/ril/reference-ril).


Thanks @Loic ,

RIL and Modem operation checked.
But device cannot get an IP address. No ‘Mobile networks’ menu to configure.
To add this menu on Lollipop, what shall I do?



I think you need to edit the framework config overlay:

I suggest you to add the mobile network attribute:
<string-array translatable="false" name="networkAttributes">

You can look at device/google/marlin/overlay/frameworks/base/core/res/res/values/config.xml for example.


VERY thanks @Loic ,

I will check the file if mobile network is added.
