No events after GPRS EVENT SETUP OK

[iliavlad]

Hi,

Could anyone help me with GPRS connection issue?

So I need send data to server time to time. I use HTTP POST and for first data exchange all comes well. But when a second connection establish, there are no events after GPRS EVENT SETUP OK.

My log is below

and no logs after ((

Connection does not establish at second time. Why?

Where should I look to find reason of the issue?

Thanks for help

Few times ago many connections established without problems and I don’t know what happens to make it .

It seems link network problem. I moved the anthenna to other place, at+csq returns 28 instead of 23 and gprs connection establishes well.
