@Leondegeling Thanks for your reply!
I’ve tried pressing the mode button in several other ways to try to get the gateway to behave differently, but all it does is power on and flash rapidly before it sits idle. No ethernet and no wifi. At this point it’s essentially dead.
It looks like I have to get a readout of the UART to see what’s going on. I don’t have the cable or board (ref. TTN Gateway - FAQ). Any idea what I need to get and where I can get it? I’m located in Norway so any online store in Europe or the US is fine. I’ll be using a MacBook to read out the data.
From reading other reports here it looks like I’m not alone. I’m surprised (and disappointed) that the TTN team is not offering any help with this.
