Re: ESP32 with Eclipse (Linux)?

Follow the tutorials from Kolban and pcbreflux as starters. For me, with only some Java background, it was very usefully.

Re: Issues with I2C? Only 1 of 4 devices found by i2cscanner.c

I noticed a reliability aspect during my endurance test of the MCP23017. After several hours the "flashing of leds "stops" while the I2C digitaWrite() receives the correct information. The rest of the endurance test (Oled displays) and more works as expected. Never used RTOS so my fir...

esp32 RTOS Paho code for an mqtt client

The Paho MQTT client was ported to the RTOS esp8266 platform. Is this the same code as the MQTT client from Angus / Tuan? See the link below: http://www.ba0sh1.com/2015/08/30/esp8266-mqtt-rtos/ In the recent Maker Faire I demonstrated an ESP8266 MQTT VFD clock. Some readers had wrote to ask for the ...

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 ...

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 de...

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?
