    Add and remove rfid tags on Nodemcu remotely via Php MySql

    naveenchand435

      I want to add and delete rfid tags from nodemcu remotely from php mysql server. As I implemented a database i understood that tag values are sent in string format using the following code client.print("/192.168.1.56/add.php?ID=5633763785

      1. Rfid tags can be read by mfrc522 if tag values are in a byteArray
      2. I can send tag values from my server in string format to nodemcu
      3. But if I typecast the strings to byte array using String.getByte(byte[], sizeof(string)) , the tag value is not same as original byte array when read by a rfid reader in real time. would some one provide any suggestions and solutions for this particula scenario.. thanks.
