Both Mode ESP8266 (AP and Client Mode)

In the previous article I made a Tutorial on how to set the mode on ESP8266, which is as an Access point or wifi station and as a wifi client.

in this article I will show you how to set ESP8266 mode to be both mode. That is, in this Mode ESP8266 can be an Access point and wif client simultaneously.

The component that you need:

• NodeMCU ESP8266
• Micro USB
• Laptop
• Accsess point
• Android Phone

I have provided Sketches for this tutorial. the sketch can be downloaded below.

Before uploading a sketch to NodeMCU, make sure the NodeMCU board has been added to the Arduino IDE. You can read it in this article "Get Started With ESP8266 (NodeMCU Lolin V3)"

To ensure that ESP8266 can be used for access points and WiFi clients together, let's check one by one.

ESP8266 as an Wifi Clients:

• Open Serial Monitor
• Press reset on NodeMCU
• If the serial monitor is displayed like Figure 1, it means that the ESP8266 has succeeded in becoming a WiFi client that is connected to an access point

ESP8266 as a wifi station:

• Open the WiFi menu on the android phone.
• If there is an access point named "NodeMCU" and you can connect to that access point, it means that ESP8266 has succeeded in becoming an access point for the Android phone.
