@Juraj can you tell me that is there any way to post an array (20 byte) using nodemcu on MySQL data base which is on my localhost. because i am getting my RFID tag id into an array! Like this FF, DE, 3E, X, X, X....... till 20 bytes– EzaNov 4, 2018 at 11:50

it is possible, but that is a different question. you would need to have a server on a computer to write the data to MySQL. and you would send data from esp8266 to this server.– Juraj ♦Nov 4, 2018 at 12:06

The interface of Sparkfun M6E Nano UHF Rfid reader is Serial TTL. So you should connect it to Serial pins of the NodeMcu. Don't use USB then, because it is connect to Serial too.
