Re: ESP32 with Arduino and MQTT publishing to the Watson IoT Platform

Hello Angus,

In mqtt.h void mqtt_stop() is missing. After adding I can build and flash and see the /test topic in my MQTTfx client.

Thanks, this is great!

ESP32 with native MQTT client

Hello Angus,

Yes I looked into your code and I will give it a try to translate to the espressif ide-idf approach.
I appreciate your efforts!

Re: ESP32 with Arduino and MQTT publishing to the Watson IoT Platform

Hello Kolban, Started the thread with the topic "MQTT client". I investigate whether I can replace an existing MQTT client ( Raspberry / java / pi4j / PaHo /display) and whether the esp32 RTOS helps me to develop time critical applications at end nodes. ( I tested the Mongoose MQTT client and the "n...

Re: ESP32 with Arduino and MQTT publishing to the Watson IoT Platform

Hi torntrousers, Yes, tested the esp32 " arduino" and the mongoose solutions. These solutions both work but I want to use the espressif / eclipse IDE. (Both also work on the cheap esp8266) I hoped someone has already done the groundwork for " Writing non ESP32 MQTT clients" as described on page 259 ...

esp32 espressif code for an mqtt client

Mongoose and Arduino publish code for an mqtt client.
Is there "working"or prototype code for a "native" espressif mqtt client?

Re: HTTP requests (GET, POST etc.) on ESP32

Thanks for your swift response. Indeed when the client closes the connection it's not waiting for the server. And the response is as expected. Never noticed the difference.

Re: HTTP requests (GET, POST etc.) on ESP32 =>> long delay

I'm also new (one day) on the ESP32 platform. The examples I tried run, except the 03_http_request. If I compare the response as seen by the ESP32 with the response as seen by the Firefox webtools, ESP32 adds a 0 at the end and tells me there is errno 128. On top of this there is a long delay (secon...
