I know you also want a WiFi/Bluetooth gateway of your own.

project description
Official description: Anxinke Wi-Fi Home Smart Gateway (ESP32-G) is designed and developed by Anxinke Technology. It realizes the functions of system information collection, information input, information output, centralized control, remote control, linkage control, etc. The device supports LAN Wi-Fi function (802.11b/g/n). It comes with a LAN port. In the LAN networking, it can support STA/AP/STA_AP working mode, and support Smart Cofig/AirKiss one-key network configuration to provide users with a high-speed, safe and reliable service. Application areas are used for automatic meter reading, home building automation, security system, and remote irrigation system.
Self-explanation: ESP32-GetWay can realize two gateway functions:
1. WiFi gateway: WiFi hotspots can be sent through devices to provide wireless services. The speed is not fast, but it is very suitable for the access of IoT devices (the number of access devices refers to the ESP32 module manual), reducing the burden on the router (in fact, it is also a small router itself)
2. Bluetooth gateway: Switch the Bluetooth gateway, you can use the Anxinke PB Bluetooth module series to realize SIG-MESH networking, and transmit data through AT commands.
3. ESP32 network port development board, this project has two built-in download methods, and the development function can refer to the Espressif ESP32-GetWay instructions (learning to use-the advantage is the low cost)
