External GPS Antenna not working

I have 2 asset tracker v2 with external active antenna, one managed to get an accurate fix under 1 minute, the other is about to go for 24 hours and no fix. Any ideas??

Let me ping someone that might be able to help, @blave are you able to assist?

You enabled the antenna using the antExternal() method, correct? The AssetTracker v2 does not auto-switch between antennas.

This firmware will dump out the debugging information from the GPS unit. It may be helpful in figuring out why one of them isn’t working.

Thanks a lot guys, it’s already working, turns out it was a malfunctioning antenna. I am surprised though because apparently the antennas are in fact auto-switching without the argument.
