Hi,
I am trying to integrate Node-Red with chirpstack version 4. I have deployed the flow provided in this link
https://www.chirpstack.io/docs/guides/node-red-integration.html#debug-events
The output of “Device event (up)” node is this
{
"deduplicationId": "b78bcd37-e171-4060-8e51-1c2c1648638a",
"time": "2022-12-16T12:58:26.491151404+00:00",
"deviceInfo": {
"tenantId": "52f14cd4-c6f1-4fbd-8f87-4025e1d49242",
"tenantName": "ChirpStack",
"applicationId": "7c7746bb-bc82-41b7-9a32-211fdcb72651",
"applicationName": "locathost",
"deviceProfileId": "5fd57ed5-cb76-4e00-ace7-3bdcb223946c",
"deviceProfileName": "device_profile",
"deviceName": "Node_506f98000000ac63",
"devEui": "506f98000000ac63"
},
"devAddr": "0000ac63",
"adr": true,
"fCnt": 4,
"fPort": 7,
"confirmed": true,
"data": "MA==",
"rxInfo": [
{
"gatewayId": "dabbccffff2a79cb",
"uplinkId": 35112,
"rssi": -43,
"snr": 8,
"channel": 3,
"location": {},
"context": "qRlwdw==",
"metadata": {
"region_name": "in865",
"region_common_name": "IN865"
}
}
],
"txInfo": {
"frequency": 865402500,
"modulation": {
"lora": {
"bandwidth": 125000,
"spreadingFactor": 12,
"codeRate": "CR_4_5"
}
}
}
}
The output of the “function” node is this
"MA=="
The output of the “device downlink” node is this
msg.payload : undefined
undefined
What should be the output of the “device downlink” node ?
Function node “on message” property is this
return {
devEui: msg.payload.deviceInfo.devEui,
fPort: msg.payload.fPort,
confirmed: false,
payload: msg.payload.data
};
