WiFi connection by mavesp8266

I’m Hiroki(I’m Japanese and I’m sorry for my poor English).
I have a question about ESP-WROOM-02 WiFi connecting pixhawk to QGC.
I would like to wirelessly communicate with QGC and drone like in this link.
I have written the mavesp8266 v1.2.2 to ESP-WROOM-02 and checked the connect to PC.

Next, I set the
MAVLink Ground Station’s Host name: “” and
Comm Links settings :UDP 14550.

However, QGC is saying “communication lost”!
I don’t know how to get pixhawk to connect to QGC…
Please give me your experience!

my settings

  • pixhawk1-1M
  • ArduCopter V4.1.1
  • ChibiOS
  • ESP-WROOM-02
  • mavesp8266
  • QGC(on M1 MacBook Air 2020)
