See [here](https://github.com/DroidPlanner/Tower/wiki/Custom-video-stream) for instructions. #### Tower App settings For telemetry, set protocol to "UDP" and leave default server port 14550. Click on "Connect". For video, change settings according to the following screenshots. Please note, the Tower App will not display the video stream if it doesn't receive telemetry.
