Hi Mick,
Apologies for the top posting…
The pi tends to attach Bluetooth to the uart that you want to use for GPS hats.
The general rule of thumb is to remove any mention of “console=serial blah” from /boot/firmware/cmdline.txt
Then
Add enable_uart=1 and dtoverlay=disable-bt to /boot/firmware/config.txt
(The first 2 instructions can be achieved by running raspi-config and choosing “interfaces” then “serial” and saying “no” to access console over serial and “yes” to enabling serial port but the disabling Bluetooth line has to be done manually)
This should allow your GPS module Hat to attach to /dev/ttyAMA0 after a reboot and all should be right.
If you really want to use Bluetooth on your time server then the following thread tells you how to attach it to the mini-uart at /dev/ttyS0 instead
Good luck.

Hi Gary,
We realise now that gpsdebuginfo interrogates the runni8ng daemon. Doh!
Here is the log when taken on a running instance.
