Gps difficulties - Cheezeitz51 - 2020-07-07
after some reboots on a fresh install my gps will stop working. It's a rp4 with openplotter 2 with vk 162/ublox 7 gps. Signalk says device or resource busy. I dont see anything else using it though. I have never had this problem before until a couple days ago. It seems when I do the following commands it will start working again (sometimes right after, sometimes it needs rebooted and it will continue to work after some reboots)
Sudo killall gpsd
Sudo killall -9 gpsd
Sudo rm /run/gpsd.sock
Gpsd /dev/ttyACM0
Sincr a couple days ago I've done multiple clean installs and tried a different pi. Any ideas why this is happening/how to fix it?

So it starts working after gpsd restart, but Signal K reports resource busy. Sounds like you have the device configured both as a serial device and as a gpsd connection?

It is only configured as a serial device as far as I can tell
RE: Gps difficulties - tkurki - 2020-07-08
If the serial device is configured in Signal K why are you using gpsd?
Next time SK reports resource busy you can see what process has the port open with
sudo lsof | grep ttyACM0

I don't know, I guess I'm not using it and got confused. It was being used by node, which I killed and then it was being used by pypilot. Which I kill but then it comes back
