Push Email heartbeat

[Guest soup dragon]

I [think] I see that the heartbeat sent by a mobile device to the push email server defaults to one beat every 120 seconds, but tests have shown that one beat per 30 mins can also be effective.

I wonder if/how this heartbeat can be changed? A registry setting I guess. That would reduce the gprs useage nicely.

EDIT:

I've now found the activesync log file and it looks like the heartbeat is 8 mins if the following entry is anything to go by:

CPingEngine PingSend Heartbeat = 480

It would still be nice to have the option to alter it. ;)

Soembody on XDA Dev has said that they changed theirs (didn't say what to, or how they did it) using a Registry key

I haven't got around to looking into it yet though...

I found the following keys in the registry, so you might want to try playing around with these:

HKCU\Software\Microsoft\ActiveSync\HeartbeatIncrement = 300 (DWORD)

HKCU\Software\Microsoft\ActiveSync\InitialHeartbeat = 480 (DWORD)

You might want to try playing around with one of these to see what the results are, but it looks like this might be what your looking for. I am going to guess that they are in seconds, so 300 = 5 minutes and 480 = 8 minutes.

Hope this helps!

If you are with a network that supports it, the heartbeat pulse is automatically set by the server. If your connection stays live, then the server/device will extend the increment automatically - saving you gprs costs.

If you are with orange though, their gprs service changes your ip address so often, the device is actually syncing every few minutes (using more data)!

OK, that's interesting. really wish O2 whould come up with a data plan to match T-Mobile then I wouldn't care less!
