Softwareserial Library Download
Allows normal IO pins to be used as bit bashed UART pins
Resources
SoftwareSerial library was modified specifically to work with the Digispark and should support all standard baud rates. TinyDebugSerial is included with the tiny core we built off of, and we have only added support for 16.5Mhz and haven't tried to do anything else with it - I imagine 57600 baud could be added pretty easily, but I haven't (until now) ever seen a need to support it. SoftwareSerial is used to create an instance of a SoftwareSerial object, whose name you need to provide as in the example below. The inverselogic argument is optional and defaults to false. See below for more details about what it does. Multiple SoftwareSerial objects may be created, however only one can be active at a given moment. At high bitrates (115200bps) send bit timing can be improved at the expense of blocking concurrent full duplex receives, with the SoftwareSerial::enableIntTx(false) function call. The same functionality is given as the corresponding AVR library but several instances can be active at the same time. Speed up to 115200 baud is supported. ESP8266 12E NodeMCU & SoftwareSerial. Test To verify the operation of the softwareserial library, I downloaded the library for esp and I have temporarily replaced the serial software version for arduino. Conclusions Although this is a basic test, it requires more complete tests regarding the configuration of more serial serial ports. The idea is to use this library.
Example Usage
Receiving Data
Note you can define unlimited software serial ports, but only 1 can be set to receive at a time.
Using only 1 pin
Using for RX only
Defining both pins as PA5 on an ATtiny841 and using to receive worked for us.
Compatibility
ATtiny841
RX on pin 2 (RB2) would not work (no explanation found as to why).
RX on pin 5 (PA5) works.
Software serial uses timer, be careful when you are using software serial. Timer is also used for WiFi communication section if you don’t give enough time to WiFi routines it will create problem of stack error or misbehavior. It is better to use software serial only when you need two serial ports and also avoid use of software serial for data reception.
Software serial can be implemented on any GPIO pin of ESP8266.
For this you need SoftwareSerial Library for ESP.

You have to import Software serial library in your program using below commands
Command format is SoftwareSerial(rxPin, txPin, inverse_logic, buffer size);

Program for software serial
We are using GPIO14 as Rx pin and GPIO15 as Tx pin Brother bear free and free download game.
Observe both serials and send some data to both serial data, data send from hardware serial is sent out from software serial and vice versa.
I will not recommend use of software serial until it becomes must. It disturbs WiFi functionality.
