[Question]-Apollo Auto can send and Receive data(like lidar and Radar) using WebSocket to Application via listen port- TCP/UPD & IP address?

[anilbommareddy]

The Apollo Auto simulator Can sends like car telemetry information the data specifications to the application using WebSocketi.e WebSocket(uWebSockets) Data-describes the JSON object send back from Application to the simulator

For sample example i.e understanding: https://github.com/shazraz/Extended-Kalman-Filter.

Here bins tested with Udacity SDC Term 2 Simulator (Extended-Kalman-Filter connected/communicat Udacity on Port TCP and data receive Json msg) Similar Apollo Auto Can be used send/receive other from other Application I think Apollo-Auto dream view connected via WebSocket. so, Apollo auto will be provided WebSocket interfaces to send/receive data to Application/Hardware-TCP/UDP port and Ip Address. ?

Yes, dreamview already use websocket to send data, you can also ref the modules/bridge module to send data to other software

@daohu527 could you please let know how to test module/bridge.?
