Hi @1chick,

I would recommend to check the helper endpoint for message example:

 curl http://blueos.local:6040/helper/mavlink\?name\=NAMED_VALUE_FLOAT                               
{
  "header": {
    "system_id": 255,
    "component_id": 0,
    "sequence": 0
  },
  "message": {
    "type": "NAMED_VALUE_FLOAT",
    "time_boot_ms": 0,
    "value": 0.0,
    "name": [
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000",
      "\u0000"
    ]
  }
}%

Thanks @patrickelectric bro!
the NAMED_VALUE_FLOAT message directly can not be sent to GCS by mavlink2rest, have to edit the code logic in ardusub's firmware function GCS_MAVLINK_Sub::handleMessage. is it right?

hi bro @patrickelectric
when post data，it response slowly，sometime need 40s. how to Optimize？
