Hi, im using a raspberry PI 3 model B+ with venus os to monitor a Smart solar 150/100 and a BMV 712. i now have bought a USB GPS antenna.
when i conenct it, the Raspberry bevomes very instable, only updating every few minutes and the VRM portal lost all its data, battery status solar.. everything gone, if i go into the GPS menu it shows "Gps connected but no fix"
when i dissconect the GPS module everything works fine...
anonye an idea?
Moved to "Modifications Space" for non-Victron-supported systems, which should increase the likelihood of other users of perhaps similar systems having some valuable input!
You have not mentioned make/model of GPS or Venus OS version. I purchase a low cost generic GPS from Amazon in 2019 I’ve had no problems on Venus OS 2.4 to 2.6.

Normally when a GPS receiver gives no fix it mostlikely doesn't receive satellites. Incase your receiver is brand new or hasn't been used for a longtime it has to download a new almanac from satellite that can take up to 15-20 minutes. That the RPI becomes very unstable might be caused by to much power drawn from its usb port. How does the GPS behave when its connected to a laptop? If it works fine on the laptop it should work fine on the RPI. Then maybe connect it using a powered usb hub.
