We are on network-server 3.16.5. Yes it is old and we are moving to v4 but things makes this not possible right now. However, most things works great but we are experiencing packet loss and have been analyzing this for a while now and it seems to boil down do som problems with rx2.
In this downlink payload everything looks good and as you can see a freq in rx2:
{
“downlinkId”: 28816,
“downlinkIdLegacy”: “cJCLeFUWSLmDNY+K9mdfAA==”,
“items”: [
{
“phyPayload”: “YNpTnQCDFA8CCAJiCnq1”,
“txInfoLegacy”: {
“frequency”: 867700000,
“power”: 14,
“loraModulationInfo”: {
“bandwidth”: 125,
“spreadingFactor”: 7,
“codeRateLegacy”: “4/5”,
“polarizationInversion”: true
},
“timing”: “DELAY”,
“delayTimingInfo”: {
“delay”: {
“seconds”: “1”
}
},
“context”: “AAAAAAAAAAAATgABB0Jaew==”
}
},
{
“phyPayload”: “YNpTnQCDFA8CCAJiCnq1”,
“txInfoLegacy”: {
“frequency”: 869525000,
“power”: 27,
“loraModulationInfo”: {
“bandwidth”: 125,
“spreadingFactor”: 12,
“codeRateLegacy”: “4/5”,
“polarizationInversion”: true
},
“timing”: “DELAY”,
“delayTimingInfo”: {
“delay”: {
“seconds”: “2”
}
},
“context”: “AAAAAAAAAAAATgABB0Jaew==”
}
}
],
“gatewayIdLegacy”: “t27oVuXAT7M=”
}
But sometimes there is no response to them and the difference we can observe is that there are no frequency in the rx2 window. Like in this payload.
{
“downlinkId”: 59913,
“downlinkIdLegacy”: “6gmBnbehRJuL4Pnzb9dq8g==”,
“items”: [
{
“phyPayload”: “YAxpFeCAAAAAuM5iMsh9br6IVVRq9e/2td/ioJqqAraDIf/YBgg=”,
“txInfoLegacy”: {

“power”: 14,
“loraModulationInfo”: {
“bandwidth”: 125,
“spreadingFactor”: 12,
“codeRateLegacy”: “4/5”,
“polarizationInversion”: true
},
“timing”: “DELAY”,
“delayTimingInfo”: {
“delay”: {
“seconds”: “1”
}
},
“context”: “AAAAAAAAAAAATgABA1luJA==”
}
},
{
“phyPayload”: “YAxpFeCAAAAAuM5iMsh9br6IVVRq9e/2td/ioJqqAraDIf/YBgg=”,
“txInfoLegacy”: {
“power”: 14,
“loraModulationInfo”: {
“bandwidth”: 125,
“spreadingFactor”: 12,
“codeRateLegacy”: “4/5”,
“polarizationInversion”: true
},
“timing”: “DELAY”,
“delayTimingInfo”: {
“delay”: {
“seconds”: “2”
}
},
“context”: “AAAAAAAAAAAATgABA1luJA==”
}
}
],
“gatewayIdLegacy”: “t27oVuXAT7M=”
}
Is there any obvious error in our config or some other explanation to this?
