Thanks - I've experimented with both approaches when trying to solve this problem so will refactor my code to make this the standard approach throughout.
The challenge is the way that the pages are built - Treating the HTML as a large string, and loading the latest data into the full html txt in ...

I'm using an ESP32 in an IoT project, logging data from a number of sensors.
I've included a built in WiFi access point and web server so I can connect a computer to the ESP32 to change settings and also to read the logged data. I've also got MQTT running as, eventually, I want the data sent ...

My code has started spontaneously rebooting.

I suspected that might be the problem.
Here's the banner on my Android phone

ps. If I put a redirect in the uri handlers, the web page opens but I get the captive portal banner again
eg
// HTTP handler for connectivity check (e.g., Android)
esp_err_t connectivity_check_handler(httpd_req_t *req) {
httpd_resp_set_status(req, "302 Found");
httpd_resp_set_hdr(req, "Location ...

I'm trying to create a web page to configure an IoT device running on an ESP32.
The idea is that the end user will connect their phone to a soft AP running on the ESP32 and then be taken straight to the web page.
I don't want the captive portal banner to appear at the top of the screen and I want ...

Thanks.
Used the code from the link + a bit more research to develop the following which works a treat


#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include <stdio.h>
#include "esp_system.h"
#include "esp_log.h"
#include "string.h"

I'm feeling particularly dumb...

Working on a project with an ESP32-S3-WROOM with built in USB port. I'm using the USB port to program the ESP32 and monitor / debug the code.

When the device first boots I need to write some basic parameters to it - these are device specific, so not hard coded.
My ...

I'm starting to add OTA update to my project, using the Espressive Native OTA code as a starting point.
https://github.com/espressif/esp-idf/blob/master/examples/system/ota/README.md

I've generated the server certificate and key, with a 365 day expiry as per the example.
openssl req -x509 ...

I've given up trying to create a solution in the firmware - found a different supplier who make an (almost) identical motor with an encoder that works correctly
