Already picking up support... ---------- Forwarded message ---------- From: Heikki Hannikainen <[email protected]> Subject: [aprsfi] X-APRS: a new protocol To: [email protected] Cc: Georg Lukas <[email protected]> Hi, I fully support the new X-APRS protocol initiative, it just plain makes sense. Experimental services are already live on aprs.fi, with IPv6 and load balancing. "telnet xaprs.aprs.fi 20482" to see the convenient, easy-to parse and lightweight data stream. https://aprsdroid.org/xaprs/ I've also set up a service on the AMPRnet/Hamnet: telnet 44.139.11.254 20482 With a little effort, I'm hoping we could phase out and turn off the legacy APRS-IS services by the end of this year. - Hessu > Hi all, > > in the past I've often realized that APRS-IS does not work well with > mobile TCP/IP - latency on 2G or 3G causes delays that skew the > position reports; interruptions in the data connection are almost > impossible to detect at application level, and thus cause packet drops, etc. > > On the other hand, with my other project (yaxim, a mobile client for > the Extensible Messaging and Presence Protocol / XMPP), all of these > problems have been solved years ago.
