WiFi Module V1.0 – ESP8266
The WiFi radio is developed around the very popular ESP8266 module used in many IoT projects. The WiFi module V1.0 comes with a standard JST-GH, allowing you to establish a UDP connection with your computer or mobile device and use mobile ground stations.
Comes with the latest Ardupilot ESP8266 firmware developed by Andrew Tridge. This new firmware has a nice web interface, MavLink2 support, and an easier way to do future updates via the web interface.

Normal Usage
Section titled “Normal Usage”If connected to Serial1/Telem1 these parameters should be set on the autopilot (if using another telemetry port, replace the “1” in the parameter name with the telemetry port’s number):
- SERIAL1_PROTOCOL = 2 (MAVLink2) or 1 (MAVLink1)
- SERIAL1_BAUD = 921 (921600 baud)
If you have problems connecting, it may help to set BRD_SER1_RTSCTS = 0 to disable flow control although this is not normally necessary
