Re: Reliable WiFi and MQTT connection and reconnection?
Well cool, that code, posted above, the ESP32 stayed connected for 24 hours. A first. Seems the MQTT callback does not like to run code.

Re: Reliable WiFi and MQTT connection and reconnection?
I, also, experience WiFi disconnects. The disconnects happen about 2 to 6 hours. I am still trying to figure out a good reconnect solution. From what I've been reading the WiFi disconnect has been an issue for sometime. To determine if the MQTT connection and path and topics are correct, I ran Node-...

Re: AWS IoT examples NO Amazon FreeRTOS?
I had a ESP32 publishing MQTT (IoT) to AWS. In IoT build the device, set its type and security. Save your certificates. In the Arduino IDE, I made a certs.h, I used PubSub to send. Connected well. My issue was in wanting to send data from the AWS IoT to the dB on my web site. I got a RPi, loaded it ...

Re: Phase matching timer interrupt sequence with LEDC PWM
Have you considered using freeRTOS and event triggers in your ISR to initiate interrupt code? #include "esp32-hal-psram.h" #include "esp_system.h" //This inclusion configures the peripherals in the ESP system. #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "freertos/timers.h" #in...

Re: Reading databurst by serial2
Sometimes using the Arduino way to get at the ESP32 functions does not work so well, as in the case of A:D conversions. That's when I turn to the ESP32 API https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/uart.html . I have found that (Serial2.available() > 0) does not...
