RAK2287 onboard gps not responding?

Hi.

I have a gateway that was running fine but since I moved it outdoors it seems the GPS is dead.

The gateway is running on. Pi3A + RAK hat + RAK2287. I checked the antenna and connectors, all seems fine. I also swapped gps antenna with one that works fine on another device.

I get nothing from “cat /dev/ttyAMA0”.

I there any other tests I could do? Where do I go from here?

Thanks
