Re: ULP with ultrasonic sensor HC-SR04 / JSN-SR04T
Aren't you interested to write it for me, based on deal for service?

Re: MQTT & MQTTS - Sample implementation for ESP32
It is required to change url, target topic, CA certificate that issued certificate for your server.
I think there should be also possible to use Certificate bundle, so it will be used "automatically" if its standard Root CA and not self-signed CA.

Re: Using ESP-IDF code in Arduino code?
Yes you can. Your Arduino code is simply... calling low-level ESP-IDF functions.
So you can skip these "macros" and call these ESP-IDF functions directly.

Re: ULP with ultrasonic sensor HC-SR04 / JSN-SR04T
Hello, I have the same issue, I want to wake up the ULP co-processor with an ultrasonic sensor. Did you find a solution for that? Unfortunately no. I haven't find any program implementation for ULP coprocessor that could I use. All available implementations around are just for GPIO control (that is...

Re: How to keep ESP32 from resetting on wakeup from deep_sleep
Sure, timer resets ESP32 main chip that is sleeping. So it will start properly from reset. There is no other option than reset main chip to wake it, because it will sleep forever without reset. You can just use other options for wakeup that will cause reset, like button a.k.a. external interrupt, ti...

Re: Using ESP.restart() not consistent on ESP32-WROOM
Yep and also, are you using EEPROM.commit() after you write into SPIFFS? You can disable interrupts using cli() or noInterrupts() function. For enable them you can use sei() or interrupts(). I am using just ESP32-WROOM-32, but esp_restart(); worked properly for me. Or when resetting call this, it wi...

If statement with WiFiEvent_t event
Hello there, I have problem with ESP32 and PHY Ethernet LAN8720 that is connected to ESP via RMII interface. I am running 2 tasks. One will do measurement and add value into Queue (FIFO buffer) and other will do data transfer over HTTP or HTTPS (based on sketch) when data are available in Queue. But...

Re: Ultrasonic sensor node ESP32 - FreeRTOS example ESP-IDF / Arduino Core
Today I have tried PHY Ethernet LAN7820 sketch on my hardware. I need to change sketch a bit due signals that are required for RMII interface and also for some outputs, because system was printing IP address 0.0.0.0, but milliseconds after that PHY Ethernet had IP and I was able to see it only in Ve...

Re: ESP32 vs ESP8266 server differences
Hello there, your changes looks okay. I am running webserver on ESP8266 and I have never used these header files. #include <ESP8266HTTPClient.h> #include <WiFiClient.h> Also for ESP32 I haven't used these: #include <HTTPClient.h> #include <WiFiClient.h> Or should I understand it like you have webse...
