1. VCC connected to 3.3V, GND connected to power ground, utxd connected to MAX232 chip RXD, urxd connected to MAX232 chip TXD, ch_ When PD connects VCC, it should pay attention to two problems: the baud rate of serial port is 9600 (sometimes 115200), and each string of characters should end with carriage return or newline.
esp8266 can be configured into three modes: station, AP and station + AP, that is to say, the mole can be used as a client to connect to the route in the LAN, or it can be set as a sever, It can also be used as the sever of other clients as well as the client in LAN!

2. PL2303 is directly connected to MCU's IO and can write program
of course, with RS232 conversion, we can stabilize CH341 - MAX232 - io

3. 1. Enter the main router configuration interface. Enable the DHCP function and configure the wireless settings, and then restart the wireless router
2. Enter the sub router configuration interface. Turn off the DHCP function and configure the LAN port address to be in the same network segment as R1. In addition, ensure that the SSID of R2 wireless router is different from R1. After setting, restart the router
3. Enter the main router, change the WDS mode to relay mode under the WDS setting, select the required encryption type, which can be WEP or WPA / PSK (take WEP as an example here), and then enter the key. Click start scan, find R2, and then save restart
4. Enter the secondary router again and fill in the same encryption method and key as the primary router. Note: the channel of the sub router should be the same as that of the main router. Click Scan to find the main router.
