[Solved] GPSD Stops receiving data when GPS uses more than 4800 baud

[McNugget]

For the past three days, I have been investigating an issue where GPS comm and sometimes even Pylot comm simply stops.


After lots of fiddling around, the only solution I could find was using a very old GPS receiver that uses only 4800 baud. My uBlox and Mediatek receivers with baud rates between 9600 and 115200 do not produce stable system on two different Raspberry Pi 3 (+) with various power supplies.

I recently upgraded to OpenPlotter 1.2 Alpha.

Did anyone else experience similar issues?

Cheers,
Timo

If I am not wrong nobody reported something similar before.

Anyway, have you considered to start using openplotter 2? http://forum.openmarine.net/showthread.php?tid=1992

it is still in beta stage but I do not think we will invest more effort in OP 1 to debug.

I have not looked into OpenPlotter 2, yet. Since I'm new to the project anyways, I might as well try it! I'll report back once I have tried it out whether it makes any difference.

The solution was to switch the USB-UART adapter. To be clear: I have a gps module that outputs uart. So I needed an FTDI232RL usb to serial module to connect it. Under Windows this works great even with clones of clones of these FTDI chips. On the Pi3 this causes problems left and right!
Switching the USB to serial converter seems to have solved my instability issues to the gps as well as to my pypilot motor controller.
