Looks like the location information is not available, ttsstatus reports:
{"eui":"AA555A0008060249","location":"0,0","status":"up","last_seen":"2015-12-07 22:58:54","remarks":"TTN Flevoland, Voiceworks #2","created_at":"2015-12-03 16:23:53","updated_at":"2015-12-07 23:00:08"},{"eui":"AA555A00080605A2","location":"0,0","status":"up","last_seen":"2015-12-07 22:58:41","remarks":"TTN Flevoland, Voiceworks #1","created_at":"2015-12-03 16:23:53","updated_at":"2015-12-07 23:00:08"},
Looking at the API results for those euis:
{ "status_packets_count": 10332, "eui": "AA555A00080605A2", "altitude": 0.0,** "latitude": 0.0,** "last_seen": "2015-12-07T22:06:11.501Z", "longitude": 0.0 },
and
{ "status_packets_count": 28023, "eui": "AA555A0008060249", "altitude": 0.0, "latitude": 0.0, "last_seen": "2015-12-07T22:05:54.923Z", "longitude": 0.0 },
No location information eitherâŚ
Have you set (part of gateway_conf):
"ref_latitude": 52.510113, "ref_longitude": 5.479591, "ref_altitude": 8,
as well as "fake_gps": true,
