## DroneBridge for ESP32

DroneBridge enabled firmware for the popular ESP32 modules from Espressif Systems. It's probably the cheapest way to communicate with your drone, UAV, UAS, ground-based vehicle or whatever you might call them.

It also allows for a fully transparent serial to wifi pass-through with variable packet size.

{% hint style="info" %}
DroneBridge for ESP32 differs from the DroneBridge for Raspberry Pi Project.\
DroneBridge for ESP32 is easier to use and set up, more robust and polished. The output power is limited to 20 dBm by the hardware. This means it is legal to use in most countries since it follows the Wi-Fi standard.\
\
However, it currently does not support video or radio control! \
The range is also limited to \~1km using ESP-NOW.

Blackbox concept. UDP & TCP connections are possible. Automatic UDP unicast of messages to port 14550 to all connected devices/stations. Allows additional clients to register for UDP. The client must send a packet with a length > 0 to the UDP port of ESP32.
