Hello, I am just starting out with ESP32 and am looking for example code for detecting frequency on GPIOs. My ultimate goal is to be able to detect the state of (4) LEDs with possible states of: ON (not blinking), OFF, 1 Hz, 2 Hz, 5 Hz -- basically detect the status and print to screen or collect t...

After trying to distract me with other work I had to come back to the problem and got it running by now. I think the main problem was timing. Also, the master seems to stop working once it tried to read without the slave having sent anything. One big issue I found was, that I had the ground connect...

Hi, I believe that you can't use Arduini based library directly into ESP32 IDF still you can confirm with SDK developers. Thank you @Ritesh for the replay I was able to use IRremote library in ESP IDF interface using 'Arduino over ESP IDF' https://github.com/espressif/arduino-esp32/blob/master/docs...

Hi, Right now, We are developing GSM based component for our product which is PPP based component and we have successfully verified it with multiple test-cases. So, I have also looked into LWIP component and found support for PPPoS as well for PPP COMMUNICATION over GSM. So, I am just worried about...

Hello ESP experts. I have tested the modbus slave example with Uart2 and everything works fine. However I need to use Uart0 instead. I have changed the console port to uart1 and changed modbus port to uart0. Even though the console is now successfully moved to uart1, but modbus doesn't work on uart...

Has anyone ever tried to write something like a persistent RAM disk for the ESP32? Our device has 16MB of memory and I would like to set aside some of that as a persitent RAM disk to hold various files that need to be accessed frequently and need to be present even after a soft reset. I don't need ...

Do you need security for data communications as well or just connection level security is OK? Hi Ritesh, thank you for your reply, I am trying to make the connection as secure as possible, so communication security is necessary as well. Any advicse on this matter is very much appreciated! Hello, So...

My mistake! The wifi_provisioning enhancements aren't available as a release yet. What I saw was the intermediate commit code which is not released yet. Hello, I think provisioning examples have been provided into ESP32 IDF into examples which is into release form I believe. Please clarify your nee...

Hi all, please, do you know, how can I start scan of the WiFi networks, when my ESP32 is connected to the AP? I don't want disconnect, when scanning. I am using esp-idf. Thank you Hello, Would you please specify your requirements into details? Which IDF you are using? On which mode you want to conf...
