I am new to sim800l and mqtt. I have gone through your videos. And I am able to subscribe and publish data using hercules terminal. However, I wanted to know how to send connect, publish and subscribe packet from serial terminal? Since there is no checkbox to select to show that data I am sending is in hex.
I am sending following packets through hercules terminal for which I am getting correct response:
connect – 101200044D5154540402003C00064142434445461A
publish – 3013000876616C6574726F6E68656C6C6F726176691A
subscribe – 820D0001000876616C6574726F6E001A
For the above packets can you tell me how can i send the same data in serial terminal (default terminal in arduino IDE)?
