Product introduction
WiFi and Bluetooth have been widely used in various scenarios, especially in terms of communication speed, which have obvious advantages. Almost all mobile phones now integrate WiFi and Bluetooth functions, but the communication distance is their shortcoming. Is there any hardware that can combine the long-distance advantages of LoRa with the advantages of WiFi/Bluetooth?
Wireless Bridge is such a product. Based on ESP32 and SX1276 chips, onboard 8M Byte SDRAM and 8M Byte FLASH, WiFi and Bluetooth can work at the same time. It is a bridge that converts “WiFi/Bluetooth – LoRa” signals to each other.
