7240 Could not get GPS time from GPS

LPWAN Industrial Gateways / Concentrators RAK7240
1

Issue:
my RAK 7240 does not include correct GPS locations. I included the system log.

Setup:
the GPS antenna is attached to the gateway and positioned outside. Running version 1.2.0064.
Reboot did not fix the problem.

NTP Time is enabled.

Hi @momo232030,
Is your gateway in “Packet Forwarder” mode?
Also, could you send me the SN(serial number) of your gateway in personal message/dm so I could check if there is something wrong with the device?

5

Yes, the gateway is in packetforwarder mode.
