kit_id
string
required
UUID of the kit.
asset_id
string
required
UUID of the asset.
command_name
string
required
Name of the command to dispatch (e.g. arm, ptz_move, reboot). Must match a command returned by List Commands.

Body

payload
object
Command-specific parameters. Must conform to the command’s input_schema. Pass {} or omit for commands that take no parameters.

Response

Returns a task object. The task is immediately dispatched to the connector via MQTT and also available for polling.
id
string
Task UUID. Use this to poll for status.
asset_id
string
UUID of the target asset.
command_name
string
The command that was dispatched.
payload
object
The payload that was sent.
status
string
Initial status: always pending.
requested_by
string
UUID of the user who issued the command.
created_at
string
ISO 8601 UTC timestamp.

Task lifecycle

Tasks move through these statuses as the connector processes them:
StatusMeaning
pendingCreated, waiting to be picked up by the connector
runningConnector has started execution
completedCommand succeeded. Check result for output.
failedCommand failed. Check result.error for the reason.

Example

import time

# Send a command
task = client.send_command(kit_id, asset_id, "set_mode", payload={"mode": "GUIDED"})
print(f"Task {task['id']} — status: {task['status']}")

# Fly to a waypoint
task = client.send_command(
    kit_id, asset_id, "goto_waypoint",
    payload={"lat": 31.1234, "lon": -93.4567, "alt_m": 50.0},
)

# PTZ camera move
task = client.send_command(
    kit_id, camera_id, "ptz_move",
    payload={"direction": "left", "speed": 25},
)

# Commands with no payload
client.send_command(kit_id, asset_id, "return_home")
client.send_command(kit_id, asset_id, "disarm")
// Set flight mode
const task = await client.sendCommand(kitId, assetId, 'set_mode', {
  payload: { mode: 'GUIDED' },
})
console.log(task.id, task.status)

// PTZ move
await client.sendCommand(kitId, cameraId, 'ptz_move', {
  payload: { direction: 'left', speed: 25 },
})

// No-payload command
await client.sendCommand(kitId, assetId, 'return_home')
