Note? 1. If you use it for the first time, the time for setting the WIFI password will be slightly longer (about 1 minute). After the configuration is completed, the next time you turn it on, it only takes 20 seconds to connect automatically. 2. If you want to replace the router, you can restart or press the S2 button (press the S2 button will clear the previously remembered WIFI account and password), reconfigure the WIFI account and password for ESP-01 in Mode 2. 3. When the ESP-01 memory router signal is weak or the connection is interrupted in the service area, the green light will go out and automatically try to connect. During this process, the button is inactive. When the green light is slowly flashing, the connection is restored. 4. In mode 1 and mode 2, the button is only available when the green light is slowly flashing or constantly lit. In other cases, the button is invalid. 5. ESP-01 has a timeout mechanism. When it has no data exchange with the mobile phone for more than 6. minutes, it will automatically disconnect the TCP connection. At this time, click "CONNNECT" on the "EasyTCP_20" APP to re-establish the connection.
