Let me put a simple question. In my configuration (and, yes, there
is an RTC on the Raspberry Pi HAT) I have two connections:
- a serial port connection sending NMEA/UBX data.
- a GPIO connection for the PPS data.
Like the Uputronics board. Having an RTC is nice.
Did you fix the issue I reported to you?
Is it acceptable practice to use a type 22 driver for NTP to get its
PPS,
Not here on the gpsd email list. Here we use the SHM NTP driver.
and at the same time to use a 28.0 driver to get GPSD's coarse
time data?
It can be done, but all you do is confuse the NTP cluster algorithm.
This appears to work correctly.
The problem is only one program can read the serial device at a time.
So without some plumbing that can not work.
