Hi,

We are using TCP/IP protocol. And for single meter having dynamic ips with previous version of Gurux net api, I am able to read data asynchronously. But now for multiple meters i am able to capture multiple socket connections but not able to read data. So please tell me about that.

Having problem in connecting multiple GPRS(TCP/IP) meters.

Hi,

I have few questions.
1. What version you are using now (Gurux.Net.dll)?
2. What was your previous version?
3. Can you read single meter with new version?

Hi,

Please find the answers as per your questions:
1.) We don't know the exact version because we are using the development kit of gurux.net for java. But in those apis ListenerThread class was not available and because of this we were not getting List<Socket> connection But now we are getting multiple clients socket connections.
2.) And with new version we are not able to read even single meter but with earlier apis we are able to read.

Thanks,

Trying to read a meter with Dynamic IP Using GXNET

The meter has been able to connect to the server, and i can read the meter from the OnClientConnect method but unable to read the meter from another method after connection has been established. Kindly help me on how to go about this?

Hi,

You need to read all data before you release the connection. Is connection established correctly?

Connection has been

Connection has been established and am able to read all data usin the OnClientConnect listenner. My question is, what if i want to read multiple meters upon the occurrence of an event, say read clock upon a button click? how do i go about it?

Hi,

Are the meters behind the DC or is each meter making own connection?

Each meter is making it's own

Each meter is making it's own connection. Not making using of a DC

Hi,

When meter makes connection OnClientConnect method is called for each meter. So you start own client instance for each meter and read needed information. After you have read data, you release the connection.

I want to keep the connection

I want to keep the connection and be able to read either of the meters, using the ip address and port of the connected meter to read it upon clicking a button. I would keep the socket connection active

Hi,

If you want to keep the connection up, you need to send keep-alive or meter will close the connection after inactivity timeout. In that case, don't call release or disconnect.
