Hi Gary. I appreciate your response. I am trying to give maximumdetails in this message, please forgive if I go overboard. As to what Ineed to accomplish, getting chrony to sync with the PPS is the mostimportant thing. I am currently getting the time for my raspberry pifrom a few time servers, and synchronizing it with the PPS for maximumaccuracy. I can continue to do this with the new set up if I need to,but only if I can make the PPS work. And anything regarding Lady Heatheris much more a want then a need.

Please note that I need to "systemctl stop gpsd.service " before I getgood output from cgps, gpsmon, or the "gpsd -D 5 -N -n /dev/ttyS0"command. This is true even after I "systemctl disable gpsd.socketgpsd.service" and then reboot. That seems to be a clue, but I have notbeen clever enough to figure it out.

Lady Heather and gpsd don't work together. What receiver to you have that
has a GPSDO in it?

I also thought that Lady Heather and GPSD weren't compatible, but a fewweeks ago I was looking through the Lady Heather manual, and under"configuring the receiver type" I saw the line "/rxg - GPSD interface(mainly a Linux thing - /ip=localhost:2947)". This seems to indicatethey do work together, although I cannot find any reference to how thishappens. I am hoping I can have lady Heather connect to GPSD over thenetwork, most likely from a Windows machine. Anyway, the GPSDO will beusing will be a Nortel/Trimble GSBW50AA or the other Nortel/Trimble witha very similar model number. I am hoping chrony will work with the evensecond pulse, but I can modify for PPS if needed. I know the 50nS pulseneeds to be stretched and inverted, that will not be a problem.

For reference, I am currently just trying to get it functioning and amtemporarily using an Adafruit GPS breakout board and converting thesignal to serial port level with one of those little MAX3232 modules. Isoldered a wire to an unused input on the MAX3232 and one from theoutput to the DCD pin on the serial port connector for the PPS. Thesignal was backwards, I'm inverting it with an ESP32. I know that addsjitter, but I'm just trying to get to work at the moment. The computeris thismodelhttps://cwwk.net/products/cwwk-x86-p5-super-mini-router-12th-gen-intel-n100-ddr5-4800mhz-firewall-pc-2x-i226-v-2-5g-lan-fanless-mini-pc?variant=44732374221032This unit will also be running VM's for the Intel version of theexcellent tomato router software (https://tomato64.org/) and freePBX fora single-line IP phone system.

What does cgps show you? Good fix?


Well, a few minutes after booting I get this.

And after a few minutes it quits saying "GPS timeout".

If I issue the command systemctl stop gpsd.service  I get the following.

If I
"systemctl stop gpsd.socket gpsd.service" And then try "gpsd -D 5 -N
-n /dev/ttyS0", I get a bunch of data which includes

You removed all the bits I want to see, please send a full log, starting
from the very first line.


Check at very end of this message, I'll run it untill the timeouts start.

Can anybody here suggest what I need to do to get this working? Or
perhaps tell me there is a problem which will prevent it and I should
just continue using the raspberry pi?

Send us at least 60 seconds of the log. The output of gpsdebuginfo, run
as root, may also be helpful.

gpsdebuginfo a few minutes after boot, gpsd.service not stopped.
