Request to send a local device command over UDP datagram. Commands are sent to the device using DeviceManager.send.
Example UDP command:
const payload = new Uint8Array([0x00, 0xFF, 0x00, 0xFF]); const command = new DataFlow.UdpRequestData(); command.requestId = request.requestId; command.deviceId = 'device-id'; command.port = 5555; command.data = Buffer.from(payload).toString('hex'); command.expectedResponsePackets = 1;
Handle the response
If the command succeeds, DeviceManager.send returns a UdpResponseData result. For commands with UdpRequestData.expectedResponsePackets set, the result contains a UdpResponse.
const command = new DataFlow.UdpRequestData(); command.expectedResponsePackets = 1; ... localHomeApp.getDeviceManager() .send(command) .then((result: DataFlow.CommandSuccess) => { const udpResult = result as DataFlow.UdpResponseData; const packets = udpResult.udpResponse.responsePackets; }) .catch((err: IntentFlow.HandlerError) => { // Handle command error });
