RPC

To send custom SNMP requests via RPC, add an RPC communication config with key-to-OID mappings.

GET request

Send a GET RPC command by specifying method: "GET" and the mapping key:

{
  "method": "GET",
  "params": {
    "key": "systemInfo"
  }
}

ThingsBoard sends a GET request to the OID mapped to systemInfo, parses the response using the configured data type, and routes the result to the next Rule Node:

{
  "systemInfo": "SNMP device"
}

SET request

Send a SET RPC command by specifying method: "SET", the mapping key, and the value to write:

{
  "method": "SET",
  "params": {
    "key": "lastUpdateTime",
    "value": "12901200312"
  }
}

ThingsBoard sends a SET request to the OID mapped to lastUpdateTime with the provided value as an OCTET STRING.
