RE: [aprsisce] Re: Server DEV
- Hi Lynn,
"I'm not understanding everything you're trying to do"
Hopefully, this will help.
The picture depicts all the pieces and connections. There are two radios;
one is dedicated to APRS, the other is the FT857D. Both software
applications, APRSIS32 and FT857D-CAT, reside on the same PC/netbook. TCIP
would be the best connection between the applications.
Note: There is no reason the FT857D can't be a IC-706 or other HF/VHF/UHF
mobile radio other than I don't have any to play with. Currently, all others
are over the horizon, out of sight.
There is only an RF connection to the APRS network. That was not a mistake
or oversight. This application is only used mobile and has no internet
connection except for occasional Wi-Fi when the vehicle is in the driveway.
The FT857D-CAT software polls the FT857D for the current frequency in use. A
packet is sent to APRSIS32, through TCIP, for transmission over RF.
The FT857D-CAT software receives packets from APRSIS32 and looks for
information such as; a Kenwood radio transmitting its frequency data or
repeater objects. The FT857D-CAT can then write the data to the FT857D when
Note: The Kenwood radios can do this between each other right now. In fact,
WB4APR calls on every Kenwood owner to do this. I am looking to getting in
on this action without buying a Kenwood. Basically, I want to trolling for
contacts on the frequency I have dialed up on my FT857D. I also use WB4APR's
other totally awesome idea of Voice Alert when traveling.
Since you have implemented a "server" function, I am thinking that
FT857D-CAT can connect as a client and hopefully get everything APRSIS32
This thinking is the basis for my original questions.
You posted a link of instructions which I have only started to look at.
Will APRSIS32 respond the same way now since it can be ran as a server?

I'm not understanding everything you're trying to do, but the new
IS-Server port in APRSISCE/32 is designed to provide the same
functionality as a filtered port on the APRS-IS itself. So, if you
follow the instructions at http://www.aprs-is.net/Connecting.aspx you
should be able to connect to either port 14580 on any standard APRS-IS
server or the local server port configured into an APRSISCE/32
instance. The only difference is that the local APRSISCE/32 server port
will (currently) only give you the data that it is configured to
receive, further filtered by your downstream client.
Eventually I hope to merge filters (within the limits specified at
http://www.aprs-is.net/javaprsfilter.aspx) from all downstream clients
with the local server's filter and provide that to the upstream APRS-IS
server. When I get this accomplished, a downstream APRSIS32 client
opening a Ranged MultiTrack would actually increase the upstream
server's filter to include the necessary components, all automatically.

PS. Just don't try to configure an IS-Server type port on a serial
device. They're only designed to work on TCP/IP connections. I have no
idea what will happen if you connect one to a COMM port.
