Hi guys,
It seems my first post was lost, so here is a new try.
I am currently developing an ofono-based GSM control interface, using
a Sagem
Hilo modem (I wrote the appropriate plugin) with the atmodem driver.
I am having trouble with signal strength reporting. The terminal does
not report
signal strength by event. Hence, it is not possible to get the value
from Ofono,
since Ofono expects it to be updated on a +CIEV event. I implemented a
new DBus method in the NetworkRegistration interface to force AT+CSQ
command and
update the property value, but this is clearly not a valid solution.
Do you know in modem specifications if Sagem is using a specific signal
strength notifications command?
If yes, then you should update in drivers/atmodem/network-registration.c
the at_creg_set_cb() function to handle OFONO_VENDOR_SAGEM case.
Thus you can use register to the good comman notification.
Could you also give us your AT log and more particulary the
"AT+CMER=3,0,0,1" answer?
Maybe, this configuration is not supported by your modem and you should
change it.
I found by looking in include/netreg.h that it should be up to the
plugin to
implement CSQ polling, however I can't find how it is supposed to be
done.
Indeed, the plugin has no access to the netreg atom nor structure, so
how is it
supposed to update one of these properties ?
Indeed, if you use it for instance with ConnMan signal strength
notification won't work or maybe I miss something.
Kind regards,
Guillaume
