Hi , everyone i imported a project regarding mqtt tls . I manage to connect it to AWS and is able to receive the sensor result as shown in the picture below
However , when i want to publish the MQTT message to turn ON/OFF the LED on my PK S5D9 board , it doesn't seem to work.
This is suppose to turn on the Yellow LED , however the LED on my board is still off . Anyone has the same issue or solution to this?
