Holystone HS200

This package contains the Gobot driver for the Holystone HS200 drone.

For more information on this drone, go to: http://www.holystone.com/product/Holy_Stone_HS200W_FPV_Drone_with_720P_HD_Live_Video_Wifi_Camera_2_4GHz_4CH_6_Axis_Gyro_RC_Quadcopter_with_Altitude_Hold,_Gravity_Sensor_and_Headless_Mode_Function_RTF,_Color_Red-39.html

How to Install

go get -d -u gobot.io/x/gobot/...

How to Use

  • Connect to the drone's Wi-Fi network and identify the drone/gateway IP address.
  • Use that IP address when you create a new driver.
  • Some drones appear to use a different TCP port (8080 vs. 8888?). If the example doesn't work scan the drone for open ports or modify the driver not to use TCP.

Here is a sample of how you initialize and use the driver:

package main

import (


func main() {
	drone := hs200.NewDriver("", "")

	work := func() {

		gobot.After(5*time.Second, func() {

	robot := gobot.NewRobot("hs200",





Random notes

  • The hs200 sends out an RTSP video feed from its own board camera. Not clear how this is turned on. The data is apparently streamed over UDP. (Reference mentions rtsp:// in VLC, I didn't try it!)
  • The Android control app seems to be sending out the following TCP bytes for an unknown purpose: 00 01 02 03 04 05 06 07 08 09 25 25 but the drone flies without a TCP connection.
  • The drone apparently always replies "noact\r\n" over TCP.
  • The app occasionally sends out 29 bytes long UDP packets besides the 11 byte control packet for an unknown purpose: 26 e1 07 00 00 07 00 00 00 10 00 00 00 00 00 00 00 14 00 00 00 0e 00 00 00 03 00 00 00
  • The doesn't seem to be any telemetry coming out of the drone besides the video feed.
  • The drone can sometimes be a little flaky. Ensure you've got a fully charged battery, minimal Wi-Fi interference, various connectors on the drone all well seated.
  • It's not clear whether the drone's remote uses Wi-Fi or not, possibly Wi-Fi is only for the mobile app.
