# MissionPlanner Setup

## MissionPlanner Configuration

MissionPlanner supports TCP, UDP and serial connections to the ESP32.\
To use UDP with the ESP32 in Wi-Fi Client mode you must choose UDPCI as a connection protocol. That way you can specify the ESP32's IP and port. The ESP32's IP address is displayed in the web interface.

### USB-Serial Connection

In case your are using ESP-NOW and the USBSerial firmware you must configure MissionPlanner in order to be able to connect to your GND ESP32 using the onboard USB connector.

{% hint style="info" %}
MissionPlanner fully supports all DroneBridge for ESP32 modes [since it was fixed](https://github.com/ArduPilot/MissionPlanner/pull/3469). The fix will be part of the upcoming releases of MissionPlanner.

[Until then you can download & use the nightly build for that fix here.](https://github.com/ArduPilot/MissionPlanner/actions/runs/12535485063/artifacts/2369275271) For it to work, you must select "Disable RTS reset ..." within MissionPlanner's settings. In case you already tried connecting (without having this setting changed) you need to unplug & replug the GND-ESP32 running USBSerial.

MissionPlanner can detect the ESP32, if the serial protocol of the ESP32 is configured to MAVLink. That is because all ESP32s will register as a MAVLink device with the GCS.

Choose your drone from the drop-down in order to use MissionPlanner as always.</p></figcaption></figure>

You can also change some of the settings of the ESP32 via MissionPlanner. Select the respective ESP32 from the drop-down and switch to the CONFIG-Tab. There you can change the parameters as usual.&#x20;

Be careful: The settings will be applied immediately and the ESP32 will reboot. This can lead to a permanent connection loss of the telemetry link if the settings are no longer in synch.
