I've tried your idea and I've saved a text file with dbus log. I think
this is the best way to monitor both connection, disconnection and
traffic.
I won't report the whole log, just a brief extract, but anyway I think
that the interesting part should be this one:
1) How to detect connection: this message appears once, when you have
estabilished a connection.
signal sender=:1.18 -> dest=(null destination) serial=15255
path=/com/nokia/csd/gprs/0; interface=com.nokia.csd.GPRS.Context;
member=Connected
string "tre.it"
string "IP"
string "gprs0"
string "1.87.169.88"
string "62.13.173.92"
string "62.13.173.93"
2) How to monitor traffic: this message appears every time there is a
traffic. The two uint64 are sent and received bytes.
signal sender=:1.18 -> dest=(null destination) serial=15266
path=/com/nokia/csd/gprs; interface=com.nokia.csd.GPRS; member=Status
array [
dict entry(
object path "/com/nokia/csd/gprs/0"
struct {
string "tre.it"
string "IP"
string "gprs0"
string "1.87.169.88"
boolean true
uint64 10528
uint64 38281
}
)
]
3) How to detect disconnection:
signal sender=:1.18 -> dest=(null destination) serial=15319
path=/com/nokia/csd/gprs; interface=com.nokia.csd.GPRS;
member=Suspended
uint32 3
string "Detached"
I've two more question now. Since I've never worked with dbus before,
is there any good example about a dbus "client" in Qt/C++?
Is there a way to "simulate" those messages, so I will be able to test
my application directly on my desktop, without having to build the
executable for N900 and test it on the device?
p.s: very last question... let me guess..... QtDbus is not available
on Qt for Symbian, right :) ?
