RE: [tracker2] Garmin "Database Error"
- Haven't seen that. Does it do it with EVERY station? Could be it's letting through a character that the GPS doesn't like. If you can, capture an offending waypoint string in your terminal program and send it to me.Scott

Subject: [tracker2] Garmin "Database Error"
Has anyone noticed with the lastest OT2 firmware a "Database Error"
comming up on Garmin units when in standard two-way NMEA mode? I
have a 176c that up until now worked great in both NMEA and Garmin
Binary mode. Now, when I try to use NMEA mode, I get a "Database
Error" message everytime the OT2 tries to send a waypoint to the
GPS. If I switch to binary, works like a charm. I checked all of my
settings and everything appears the same.
Just curious if anyone else saw this.
- Maybe after the cleanup and refactoring is done it'll be more practical to migrate to Java.I do worry about cross-platform serial support though. Many high-level packages just don't cut it. At least I don't have to have it send a break signal like it used to, but there's still quite a bit of baud rate switching and flushing and such going on. It has to send reset sequences at several different rates and get back to 19200 baud within a few hundred milliseconds to listen for an ACK. Even adding a USB adapter into the mix complicates things because of the added latency and the variation in how they respond to baud rate changes.I'm working to simplify things, but some of it is still going to be a little funky.Scott

Also, Java has good cross platform serial support these days. RXTX has been
working flawlessly for me.
In general I'm not a big vocal proponent of Java, but this seems like a great
app for it. I've been writing some similar programs and they have been very
easy to put together a quick GUI for talking to a serial device.
