Has this been resolved? I have exact same issue

Hello @Nick @Daey,
Which firmware version are your gateways running?
Could you provide some more logs?

Best Regards

Hi Nikola,

note that the gateway is otherwise working ok. also the unit does not have GPS, and there is no GPS antenna attached.

Firmware Version 1.2.1_RAK rRAK-544bc84

Your gateway provides no GPS values which is the reason for this error.

Hi Nikola, is there any negettive effect from reporting this error every second? The entire log is dominated by thousands of this error messag, so it would be good to disable the error message if possible?
