Re: wifi task interfering with loop() task on app core?

Assuming you are not running RTOS, the default core where Arduino code will run is on core 1. Core 0 is where the WiFi will run so it will not interfere with your code. As mentioned, post the code so can help you debug :geek:

Re: How to get one ESP32 trigger another ESP32 to do some task ?

What do you want to achieve? Give us more details please. You can connect two analog pins (and ground) together, set 1 pin to high and the other to low, check for state changes to trigger your task. Or you can setup a client server/server HTTP, and send data across. Or connect via serial ports to se...

Re: xTaskCreatePinnedToCore doesn't work for Core 1

I found this YouTube tutorial very handy : https://www.youtube.com/watch?v=k_D_Qu0cgu8 1st problem I ran into was stack size in the xTaskCreatePinnedToCore parameters. Changed it from 1000 to 4000. Next I experienced watchdog timer issues, but that is a different problem altogether. Since things lik...

Re: From WiFi to Cellular 4G

Answering myself again. Made some progress! There are GSM libraries in the Arduino IDE, some of them actually support PPPos functionality. There are even sample code under examples, INCOMPATIBLE, GSM, and yes, there seems to be compiler problems like :"fatal error: avr/pgmspace.h: No such file or di...

Re: From WiFi to Cellular 4G

To answer myself, I came across this : https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/include/lwip/netif/ppp/pppos.h So it is possible to use PPPos (PPP over serial) in the Arduino environment since it is implemented. Now if anybody can point to to an example on how to use it.... p...

Re: how to pass values from esp32 to html like web server

Hey, You probably want to get a web server going 1st: https://randomnerdtutorials.com/esp32-web-server-arduino-ide/ Once you have that working, there are various ways to display content, you can move onto something like AJAX which will help you gather real time data from the ESP32 back to your brows...

From WiFi to Cellular 4G

Hi all, I have built a project utilizing Wifi on the ESP32 module. Using RTOS I am running a web server on 1 core and a web client on another core. This works very well and I can access the web server remotely via my browser and the WiFi IP address. The Web client reads some sensors and sends the da...
