WARNING: [gps] could not get GPS time from GPS

My Gateway is RAKWireless gateway RAK2245 version 2.9.2R with a firmware RAK7243_based_on_Raspbian_OS_V2.9.2_20190820. Following the Get Start pdf i installed and configure the gateway and all it works except the gps.
I checked the serial and the gps is on ttyAMA0 and i get NMEA output from it.

i tried to stop ttn-gateway.service and start the start.sh with sudo ./start.sh inside /opt/ttn-gateway/packet_forwarder/lora_pkt_fwd but it don’t work.

Can someone help me?

You’d better take the corresponding firmware and test it again, which may be the root of the problem.


I installed the corresponding firmware but it don’t work. I’m still receiving the same error.

Make sure your GPS antenna is connected to the board and can pick up GPS signals, and make sure your raspberry pie has enough power to power up. If the same problem still occurs, please send the screenshot to me. Thank you.
