TTN Indoor Gateway and Join Requests with adeunis test device does not Join

Gateways TTIG - The Things Indoor Gateway

Hi Guys,

i have setup TTN Indoor gateway with success and can see join requests and join accepts of my Adeunis Test Device… But it doesnt join :frowning:

What i am doing wrong?

Normaly it joins without problems here in Hamburg to other public gateways, but not to my indoor gateway…

“rssi”: -9,
“snr”: 9.5,

looks like you’re standing next to the GW ?
try walking away 100 meters

Hi Borroz,

thanks for the idea. Will later test it with larger distance (and not 50cm).

I keep you/forum updated.

Nope, still does not Join…

Must be somehow a logical problem?

Finding another interesting point:

In the Application Data Window i can see that device tries to register on dfifferent gateway and on my gateway. But the date/time is broken:

{
“time”: “2019-09-09T14:59:48.340661776Z”,
“frequency”: 868.5,
“modulation”: “LORA”,
“data_rate”: “SF12BW125”,

},

“channel”: 0,
“rssi”: -70,
“snr”: 8.5
}
]

has my gateway maybe no timesync?
