must be in horizontal position with plugged USB C.

but, when the wallplug is in horizontal position 
?
No, doesnāt work. You would need a 90 dregees USB-C for this, then it could work.
Also being confused by the TTN outage at first (that was not on status.thethings.network? but most of my gateways appeared down anyway) Iāve got the unit working as well.
What Iām surprised about, is the reception of LoRa, and Iām curious about experiences from others. I see some frames being received by gateways on the other side of town but not this gateway (for a sensor with SF11) and another sensor with SF9 only comes in when I turn the gateway towards it. Sometimes. Without any user-interface itās hard to diagnose whether the WiFi signal is good, yet the ālast seenā messages appear to come in at the same time. Other experiences?
Thatās how the Giveaway-device (868MHz) looks from inside:

That answers the question if a simple firmware upgrade could change a US915 unit into a EU868 unit (while the antenna would be troublesome then). No, that would at least need some soldering as well:

Is that a 0 ohm resistor or a PCB trace (that will have to be cut)?
maybe itās only a passive āDIP-Switchā which is read by firmware?
Given the distance from the antenna and its connector on the very same board, Iād guess it doesnāt change much in that antenna path. But this is not my area of expertise at allā¦ Maybe some might be able to tell us if the chip sets would support multiple regions to start with?
As an aside, the āalso availableā made me laugh; apparently it needs to be mentioned separately?
I have followed these steps. After reboot how do i register it in the TTN console? thanks
Seems to be 0 Ohm resistor, as measured as 0 Ohm resistance.

ok finally got it. I found EUI in its page and add it in the console registration page! Now is online.
After this morning
Online, get data from it. So it works
Now look how we get more info out off the GEMTEK-box
Powered over USB-C are 230 volt connection both are working well.
Thanks DMTH for the look inside
The four solder pads in a row certainly looks like a good candidate for being a UART interface.
Maybe the āalso availableā version is 433MHz, or whatever that band is. In an ideal world, there would be differences in passive components leading to the antenna and the antenna itself, between the US and EU versions, but itās far from an ideal world these days. So many modules for sale that include 2.4ghz wifi antennas, instead of 900MHz antennas, according to actual tests run by people with rf equipment.
I have tested is and it is a UART. Some output.

Pin close to GND is TX from gateway

All gateways I know have (notch) filters so I doubt you can really get a worldwide gateway.

I have added the wifi ap, selected the legacy packet forwarder and used the mac-address within in the middle part described above, but no connection. Could anyone help?
Or you place it on a small cardboard packing box. With a hole for the USB-c connector 
Then you can just put it on your desk
