Gpio pin To Tx Rx in node mcu ESP 8266

can you please help me out wether i can use in esp8622 gpio pin to rx and tx means D0, D1

Well i believe you can? But Iā€™m not 100% sure. Well tx is to send data and rx is to read the data so if you code it in a way that is similar to the functionality of tx and rx in Arduino then I think you can.
