Hi Jonas,
Thanks for the patch.
With your patch, ofono is able to recognize LARA modems.

Error activating /ublox_0/context1: org.ofono.Error.NotAttached: GPRS is not
attached
Without ofono, I am able to activate the context and get GPRS. With ofono
only I am getting below error.
Let me know if I am missing any configuration.
In source code (drivers/ubloxmodem/lte.c), I found AT commands specific to
TOBY module for configuring the PDP context (Eg: UCGDFLT).
Whether any flow need to be modified for LARA-R2?
Regards,
Krishna

Subject: [PATCH 1/1] ublox: detect and support LARA R2 series

Hi Krishna,
This patch isn't tested, but this is roughly what you'd need to get the LARA
R2 detected and running. After that, it's just a matter of going through
the details of where ofono has issues.
>From what I can see at a quick glance at the documentation, there's nothing
that particularly stands out here so I suspect things will mostly just work.
Give the patch a try and let me know how it goes.
Regards,
Jonas
