Hi,
I am trying to read a Hexing ATC dlms meter while console app. The connection gets stuck at _settings.Client.AARQRequest()
Connection settings: InterfaceType.Hdlc, Password.None, Client Address: 1, Server Address: 1, useLogicalNameReferencing: true.
I have even set these settings and tried again but nothing changes:
Client.HdlcSettings.MaxInfoTX = 512;
Client.HdlcSettings.UseFrameSize = true;
Their own software log below:

Hi,
Hi,
There is an issue with the meter. The meter returns that the maximum receive frame size is zero in UA frame and this is an invalid value. This basically means that the meter can only send push messages and can't receive any data from the client.
You should info the meter vendor about this.
You can handle this error if you manually set MaxInfoTX like this before you call AARQRequest:
_settings.Client.HdlcSettings.MaxInfoTX = 512;
Hi Kurumi,
Hi Kurumi,
I have added manually the MaxInfo setting before calling AARQRequest before calling as you said.
It throws an authentication exception.
