Projects Networking, Protocols, and Devices

just restart with
Arduino IDE 2.3.4
RPI PICO W (RP2040)
and have old MQTT software connecting to local RPI4 Mosquitto NO TLS
using:

// MQTT PubsubClient by Nick O'Leary 2.8.0
#include <PubSubClient.h>
// old most easy mqtt lib, works NO TLS, local RPI broker .. NO send feedback provided?

when i checked last year not find about how to use TLS
is there any news? what lib can i use for that?

Nothing to work with here. What did you expect to happen, what actually hapened.
Postcode and any error logs in code tags.
Post a picture of hand-drawn wiring.

@sonofcy
sorry but your answer is OFF

have you used PICO W and MQTT with a TLS connection?

possibly you need to reread the title?

ok, i needed some time,
-1- broker RPI Mosquitto no TLS
-2- broker HIVEMQ TLS ( free account )

got a ESP32S3 using internal lib <MQTT.h>
and a PICO W using loaded old <PubSubClient.h>
working see:

i have no idea if that is state of the art,
esp the ESP32 lib search easy leads you to old stuff,
hope it helps someone
