I see data in Gateway, bot don't see in Application

ChirpStack Application Server
1

I use Chirpstack Gateway OS with different gateways (Ebyte, Waveshare, Electow) and different end nodes. I found that some of end nodes with some gateways do not works right: I see data from end nodes in Tenants/Gateways/LoRaWAN frames, but I don’t see the same data in Tenants/Applications/…/LoRaWAN frames. Where I need to look for the reason?
Here is an example of data frame in Tenants/Gateways/LoRaWAN frames:
{
“phy_payload”: {
“mhdr”: {
“m_type”: “UnconfirmedDataUp”,
“major”: “LoRaWANR1”
},
“mic”: [
31,
121,
214,
233
],
“payload”: {
“f_port”: 2,
“fhdr”: {
“devaddr”: “014fd79a”,
“f_cnt”: 6,
“f_ctrl”: {
“ack”: false,
“adr”: true,
“adr_ack_req”: false,
“class_b”: false,
“f_opts_len”: 0,
“f_pending”: false
},
“f_opts”:
},
“frm_payload”: “5096c6e830b13c0af5c7e2”
}
},
“rx_info”: [
{
“channel”: 1,
“context”: “fsPbDg==”,
“crcStatus”: “CRC_OK”,
“gatewayId”: “0016c001f132d887”,
“location”: {},
“metadata”: {
“region_common_name”: “RU864”,
“region_config_id”: “ru864”
},
“nsTime”: “2025-03-10T06:42:42.826115245+00:00”,
“rssi”: -80,
“snr”: 13.75,
“uplinkId”: 778197416
}
],
“tx_info”: {
“frequency”: 869100000,
“modulation”: {
“lora”: {
“bandwidth”: 125000,
“codeRate”: “CR_4_5”,
“spreadingFactor”: 7
}
}
}
}

Likely these are uplinks from devices on other networks that your network can’t decrypt. Hence they don’t have a device to fall under in the tenant/application/device.

No, this is my devices. I see their IDs and I see data if and only if I send the data from and devices by hand.

Do you have a proper profile defined for this device?
Do you listen to data sent from your device to GB using a UART monitor (for example, an Arduino IDE serial monitor)?
Have you registered DevEui and AppEui?
Are the above Eui inserted into the device definition at the right places?
Do you have a device with this profile attached to your application?
Is the region device the same as the region on the device configuration?
