Re: GPS Devices tested with gpsd V3.22 on Raspberry PI Zero 2 W/BullsEye Raspbian

[Don Rolph]

OK I went and looked at gpsd 3.23.2.

I can compile gpsd 3.23.2 successfully BUT the library calls appear to have changed and I can't compile direwolf against the gpsd 3.23.2 libraries.  So moving to gpsd 3.23.2 is not feasible at t his time.  I will have to stick with gpsd 3.22 for the moment.

I find it puzzling that it wold be work to match baud rate of 9600 for MT3333 and Stratux GPYes 2.0 since both autobaud to 9600 baud under 3.17 as supplied by Raspbian buster.

In any event these units do work with gpsd 3.22 IF speed is set to 9600.

Which is one of many reasons why 3.23.1 is out, and 3.23.2 coming soon.
Autobaud works much better now.

3.22 is 18 monhts old.  Don't use it.

Changable, with some effort.

Avoaid anything u-blox less than 8.
