Re: [MM] [PATCH] modem: use +CEREG to determine EPS network registration status

[Ben Chan <benchan chromium org>]

Thanks Aleksander.

I committed a a patch to the Chromium OS tree to enable EPS registration check for the novatel-lte plugin. I'd like to see if you and Dan would like to enable it for any LTE-capable modem by default. If so, I will submit a follow-up patch to the modem code instead of the novatel-lte plugin.

I just pushed the v2 patch now. Whenever we can test it properly I guess
we can enable this by default, so not a big deal.

Ben, will you send a patch to enable it in the novatel-lte plugin?
