Question 1

How do I flash DroneBridge firmware onto my ESP32?

Accepted Answer

Use the official online flasher at drone-bridge.com/flasher for the easiest method, or refer to the wiki for esptool alternatives. Precompiled binaries are available, but ensure your ESP32 board is officially supported for reliability.

Question 2

Can DroneBridge ESP32 be used for FPV video feeds?

Accepted Answer

No, it's telemetry-only and lacks video encoding support. You'll need separate hardware like a video transmitter for FPV, as the README confirms no camera connectivity.

Question 3

DroneBridge ESP32 vs Holybro telemetry radio: which is better?

Accepted Answer

DroneBridge is open-source, cheaper, and offers encryption, but requires DIY setup. Holybro radios are more expensive, proprietary, and often plug-and-play, with potentially better out-of-box range but less customization.

Question 4

How to connect DroneBridge to a Pixhawk flight controller?

Accepted Answer

Wire the ESP32's UART pins to a spare serial port on the Pixhawk, set the port protocol to MAVLink in the flight controller config, and configure DroneBridge via its web interface to use the same baud rate and protocol.

Question 5

Is the encryption in DroneBridge secure for commercial drone shows?

Accepted Answer

Yes, AES-256-GCM is industry-standard and secure for telemetry data. The Drone Light Show Edition adds safety features, but always audit keys and network setup for critical deployments.

Question 6

What's the maximum number of drones in a swarm with DroneBridge?

Accepted Answer

Limited by ESP32 processing power and channel capacity; ESP-NOW supports multiple drones, but for large swarms, test network congestion and consider the DLSE version for optimized management.
