Help on just a simple SIM808 MQTT



I am trying to follow the demo on the youtube and I am not getting the same results as he does on youtube.

The code seems the same and I get weird letters on serial monitor. It is sending the using AT+CIPSEND

but not showing on the websocket ui on cloudMQTT

Could someone help me on this?


The weird letters are Binary data. Use TMFT or Docklight software to view the binary or hex data.
Put enough delay before you send any AT command after power up.
