I have the following data:
#define MQTT_HOST IPAddress(169,254,97,145) //MQTT BROKER IP ADDRESS
#define MQTT_PORT 1883
#define BROKER_USER “paulo”
#define BROKER_PASS “abc12345”
In terminal I have:
pi@raspberrypi:~ $ hostname -I
169.254.97.145 192.168.1.204
In terminal I use:
mosquitto_pub -u esp32 -P myesp32 -t testTopic -m “Hello world!”
mosquitto_sub -u paulo -P abc12345 -v -t testTopic
What is my mistake?

This must work with wifi: inet 192.168.1.204

Hi.
I’m sorry, but can you provide more details about your issue?
What errors messages do you get on the serial monitor?
Why are you using two different MQTT users ?
Regards,
