Hi Rohit, On 07/04/17 21:16, Rohit Agrawal wrote: I can try to explain the process, which I went through myself a short while ago with a Telit/Qualcomm QMI modem. 1. You need to look at plugins/udevng.c - the first important structure is: struct vendor_list[] - it assigns ofono driver name to udev devices, based on linux driver name, and vendor/product IDs - the second one is: struct driver_list[] - it matches ofono driver name to a setup function - then you go to a setup function - for my modem, I had to create setup_telitqmi() - my modem creates several devices: qmi_wwan, cdc-wdm, and a bunch of usb-serial "option" adapters. You have to filter the ones which are required, based on device/subsystem IDs - for QMI, you need the qmi_wwan and cdc ones. 2. Plugin file - Most QMI modems should behave quite similarly to each other. A generic plugin for them is plugins/gobi.c - I selected it in udevng.c:setup_telitqmi() by doing this: ofono_modem_set_driver(modem->modem, "gobi"); - Additionally, my modem required setting two optional flags, to go through slightly different code paths: ofono_modem_set_boolean(modem->modem, "ForceSimLegacy", TRUE); ofono_modem_set_boolean(modem->modem, "AlwaysOnline", TRUE); Other QMI modems may or may not need those. 3. Driver - The gobi plugin will instantiate the main driver code in: drivers/qmimodem.c If you are lucky, and your modem is not too different to other QMI ones, you will only need to add your vendor/product/device IDs to udevng.c Hope this helps.

Hi Alfonso, Isn't the master branch at https://git.kernel.org/pub/scm/network/ofono/ofono.git/ supposed to support Android RILD based modems ? My understanding says even MediaTek modems should be covered under this. The code at location https://github.com/rilmodem/ofono is based on ofono version 1.12 while the latest ofono code version is 1.19. I don't want to work on multiple versions of ofono. Could you elaborate on why such a difference ? Not sure what special support is present at location https://github.com/rilmodem/ofono which is not present on master branch of ofono (Official). It would be great if you could put some light onto this. -Rohit On Mon, Apr 10, 2017 at 3:27 PM, Alfonso Sanchez-Beato < alfonso.sanchez-beato(a)canonical.com&gt; wrote:

There was a big refactoring when the RIL code was incorporated upstream, and our branch has not been rebased yet. You can either use our branch or try to take MTK parts to upstream. It would be some work, but should not be that hard.
