Overview
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 call them.
It also allows for a fully transparent serial to wifi pass through with variable packet size (Continuous stream of data required).
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.

Wiki Overview
Features
Bidirectional: serial-to-WiFi, serial-to-WiFi Long-Range (LR), serial-to-ESP-NOW link
Support for MAVLink, MSP, LTM or any other payload using transparent option
Affordable
Up to 150m range using standard WiFi
Up to 1km of range using ESP-NOW or Wi-Fi LR Mode - sender & receiver must be ESP32 with LR-Mode enabled
Fully encrypted in all modes including ESP-NOW broadcasts secured using AES-GCM 256 bit!
Weight: <8 g
Supported by: QGroundControl, Mission Planner, mwptools, impload etc.
Easy to set up: Power connection + UART connection to flight controller
Fully configurable through an easy-to-use web interface
Parsing of LTM & MSPv2 for more reliable connection and less packet loss
Parsing of MAVLink with the injection of Radio Status packets for the display of RSSI in the GCS
Fully transparent telemetry down-link option for continuous streams
Reliable, low-latency
Blackbox concept. UDP & TCP connections are possible. Automatic UDP uni-cast 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.
