To summarize, don't over complicate things: 1) Do not use ubxtool -f 2) Be sure gpsd is running, with the "-n" argument, and cgps has a fix. 3) Then run: ubxtool -p MON-SPAN -P 27 -v3 > # ubxtool -p MON-SPAN -P 27 -v3 -f /dev/ttyAMA0 > And that's it. No more output. Many ways that can fail, so do not do that! Enumerating all the ways it can fail is out of scope here. > Then I thought maybe is this device interfering with running "gpsd". Most certainly. Only one program can open a serial port at the same time. If gpsd had the port, then ubxtool can not get the port. > UBX-MON-VER: > swVersion EXT CORE 1.00 (f10c36) > hwVersion 00190000 > extension ROM BASE 0x118B2060 > extension FWVER=HPG 1.13 > extension PROTVER=27.12 > extension MOD=ZED-F9P > extension GPS;GLO;GAL;BDS > extension SBAS;QZSS I have pointed out before that version 1.13 is way out of date. 1.51 is current. That is a LOT of bug fixes. Gen9 changed a LOT of things in firmware, and it took them a while to get it right. > > The MON-SPAN -v 3 is designed to be easier to parse.

Really? MON-SPAN is raw data. What did you change that affected things? RGDS GARY --------------------------------------------------------------------------- Gary E.
