TSIP is an engineers dream, very over complicated. Not all TSIP is the same the guidance dictates the connection requirements.
This converter is snapped up by agra-gps, so I cannot divulge too much on its code.
All the documents you need can be downloaded directly from Trimble Website, they have a TSIP Manual and a suite of TSIP reference material available free of charge. Also found more info by reading their manuals unrelated to the ag receiver.
Its not a direct 1:1 data conversion from UBX to TSIP, much transformation of the data is required.
I started coding C in October, started the version for 250/500 in January. Hopefully will be fully vetted and released by next year.
I now have a Topcon unit in a combine available to me, so that is the next receiver to decode.
I read TSIP Reference, multiple revisions of Trimble Standard Interface Protocol and everything else I found on the Trimble website and by searching the web.
But information/documentation about 0x8f-a7 is nowhere to be found. it varies in length, pretty sure byte5-8 is time of week
Time for an update. For the past year i kept working on this project every now and then. It took a lot of trail and error and reverse engineering, but i got it running with minor hiccups. TSIP is a big mess. A lot of messages are device specific, some are not documented (not publicly accessible). For now i am done with it.
Recently i got my hands on a Novatel Smart7. With a fully documented API, it took me about 1 day to get a first prototype running.
Amazing work. Can you explain where does the RTK / centimetre level authorization come from? Is it from the STW box or does the GNSS receiver need to inject some info? Thought it would be protected by some RSA or the like and difficult to solve for the third party.
The status page shows GPS + Glonass satellites, is that just a Fendt UI issue as the OEM product too supports all constellations? 12 satellites only because of the NMEA message limitation?
Hi did this get commericalised? Is it possible to buy the convertor. I got lost in tsip and had to give up. While I use AOG now in main tractor still have a 500 that would be good to breathe new life into!
