MicoAir WiFi Link – Dual-Band WiFi 6 Telemetry Module

The MicoAir WiFi Link is a compact dual-band WiFi 6 telemetry module designed for wireless flight controller configuration, telemetry communication, and multi-drone networking. Supporting both 2.4GHz and 5GHz WiFi, it provides a convenient wireless connection between a compatible flight controller and Ground Control Station (GCS).

Built around the ESP32-C5, the MicoAir WiFi Link supports WiFi 6 (802.11ax) along with backward compatibility for 802.11 a/b/g/n/ac. It can operate in AP mode for a direct connection to a PC or smartphone, or in STA mode when connecting through an existing WiFi router.

The module supports bidirectional Serial-to-UDP transparent transmission, making it suitable for wireless communication with flight controllers running platforms such as ArduPilot and PX4. It can also be used for drone swarm networking, robotics, and other unmanned-system applications requiring wireless serial data communication.

Wireless Flight Controller Telemetry

The MicoAir WiFi Link provides a wireless connection between a flight controller and compatible Ground Control Station software. This can eliminate the need for a physical telemetry cable during configuration and testing.

The module supports telemetry serial baud rates from 57,600 up to 921,600, with 115,200 baud configured as the default. The flight controller's serial-port baud rate must match the module's configured telemetry baud rate for proper communication.

Supported GCS applications include:

Mission Planner
QGroundControl (QGC)
MicoPilot

AP and STA WiFi Modes

The MicoAir WiFi Link supports two main networking modes.

AP Mode

AP mode is the default operating mode. The module creates its own WiFi network, allowing a PC or smartphone to connect directly without requiring an external router.

The manufacturer specifies a maximum AP-mode range of 100 meters when tested in an open environment without interference.

STA Mode

In STA mode, the module connects to an existing WiFi router. The Ground Control Station and telemetry module can then communicate through the same local network.

MicoAir specifies a maximum STA-mode range of 500 meters when using a high-power router in an open environment without interference. Actual communication distance can vary depending on the router, environment, antenna setup, interference and other network conditions.

Multi-Drone Networking

The MicoAir WiFi Link can also be used for multi-drone networking. When configured in STA mode, multiple telemetry modules can connect to the same local network, allowing a Ground Control Station to communicate with multiple flight controllers.

For multi-drone setups, each telemetry module should use a unique IP address and each flight controller should be assigned a unique system ID. MicoAir's networking guide provides configuration examples for both ArduPilot and PX4 systems.

This makes the module suitable for applications such as drone swarm operations, light shows, waypoint management and centralized flight-controller monitoring.

BLE Connectivity

The MicoAir WiFi Link also includes BLE serial transparent transmission. Bluetooth connectivity is currently supported by the MicoPilot Ground Control Station application.

The specified BLE communication range is up to 10 meters.

BLE and 2.4GHz WiFi cannot be used simultaneously because they share the same physical antenna and channel. The factory configuration uses 5GHz WiFi AP mode + BLE. Switching the module to 2.4GHz WiFi disables BLE automatically.

Flight Controller Connection

The telemetry interface uses 3.3V LVTTL serial communication. When connecting the module to a flight controller:

Connect TX to RX
Connect RX to TX
Connect GND to GND
Ensure the flight controller serial-port baud rate matches the module

The USB Type-C interface can be used separately for configuration through AT commands and firmware updates.

Configuration

The MicoAir WiFi Link includes a built-in web configuration interface that can be accessed in AP mode through:

192.168.4.1

Basic WiFi settings can be configured through the web interface, while additional parameters can be configured using AT commands through the USB serial interface.

The module's default debug baud rate is 115200, while the default telemetry baud rate is also 115200.

Firmware updates can be performed using MicoAssistant, MicoAir's configuration and firmware utility.
