U-Blox modem sends unprintable chars before "AT+CGMS=<seq>" reply: ofono (1.16) close the serial port ?
12:45 a.m.
Hello,
I'm using ofono 1.16 with some patch to add sms manager to the Ublox driver.
Someone could confirm that ofono close the serial port when it receives
some unexpected/unprintable character before the "AT+CGMS=<seq>" reply
from
the modem?
If yes, is possible to discard these characters instead of hanging-up the
serial port? Could I have some info about the source I have to patch ?
Thanks in advance,
FabioT

No, oFono does not close serial ports because of garbage. The syntax
will generally discard / ignore AT commands that are not properly formatted.

Feel free to provide AT command logs to help us better understand what
is happening.

You are right, it was my misunderstanding.
What actually happens is that some layer under ofono (maybe the acm-adc
driver of our "old" kernel 2.6.37), detects an error in the communication
and close the port: simply ofono gets an HUP error on the "modem" port and
stop receving any data.
I don't think this issue should be resolved in ofono.
