There are two general connecting methods for the Wi-Fi module:
1. Module self-processing:
The indicator lights and network configuration buttons are led out from the module, and the network configuration indicator processing is handled by the module software. In addition, wiring only needs to connect the serial port to the MCU;
2. The module matches with MCU:
The module is only connected to the serial port of the MCU, and other network configuration buttons and indicators are completed by the MCU, and the network configuration logic is also determined by the MCU. The initialization module must report and reply to the working mode.
