Description
Summary
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.

FAQ
No. The current version is actually a development kit that requires you to set up features through code, and we provide the development environment: Heltec ESP32 development framework
Yes, but the battery interface is inside the device, and the shell needs to be opened. The interface is 1.25X2 lithium battery interface.
