Gateway is flooded with packets

Hello All!
Fascinated by the community and the possibilities of lorawan I put a puplic TTN gateway into operation a week ago (Raspi with IMST and outdour antenna). The first days I saw only my own test devices in the gatway traffic logs but since yesterday the gateway is flodded with packets.
Every 6 seconds there is a packet from the same device id with a network id 0x0b (Network: EveryNet, Region: Russia) with spreding factor of 12 and a bandwidth of 125, coding_rate “4/5”. The device randomly sends at 686.1 , 686.3 and 686.5 MHz. Payload is 27 bytes and air time about 1650ms. rssi is about -105, and snr about 7.5.
Does anyone have any idea what kind of device this can be?
Does the id speak for a russian device? (I have some Russian neighbors)
What would you do here, after all, it’s far outside the 1% duty cycle limit.

Location is Augsburg, Germany.


No the signal don’t come from your neighbours because SF12 / RSSI -105 / airtime indicates that’s it’s travelling a distance… maybe even 10 km or more.

maybe you can make a screenshot from your TTN console showing such a packet with all metadata

Here are the data:
“gw_id”: “eui-b827ebfffe265f55”,
“payload”: “QHE2iBeAiTYB+Hwr2SZBMAerXX23P+fDxuC+”,
“f_cnt”: 13961,
“lora”: {
“spreading_factor”: 12,
“bandwidth”: 125,
“air_time”: 1646592000
“coding_rate”: “4/5”,
“timestamp”: “2019-03-12T09:40:56.821Z”,
“rssi”: -98,
“snr”: 6.8,
“dev_addr”: “17883671”,
“frequency”: 868300000

Definitely not a TTN registered device, The Things Network Foundation has a 7-bit device address prefix from the LoRa Alliance. This means that all TTN device addresses will start with 0x26 or 0x27.

The 0x16/0x17 prefix seems to be Russia: EveryNet (0x0b)

Looks like the owner of the device is reading this forum! :thinking:
Not a hour after I have wrote this thread the devices stopped sending! :blush:
Weird coincidence…

that’s nice of him :+1:

Might have been a short test of some one with a local LoRaWAN server.
