Re: SerialBT.println failing when callback contains delay() command

Still having a problem with this. I can get it to either show the message over Bluetooth or disconnect but not both. I've tried various combinations of BT commands. New code below. Using Platformio this time. #include <Arduino.h> #include <BluetoothSerial.h> const char *bluetooth_name = "projectx2";...

SerialBT.println failing when callback contains delay() command

In the code below if I uncomment either the delay() or restart() lines I don't receive the 'Restarting...' message on my phone. I can understand why just restarting with a delay might kill the serial Bluetooth message before it's sent but why would just a delay command affect it? void callback(esp_s...

Should f_findfirst be available when the define FF_USE_FIND is set?

I'm trying to build a directory lister using FatFs with VFS for an SD card reader. I get an undefined reference error when I try to use f_findfirst even when I change the FF_USE_FIND define in ffconf.h Should I be able to use f_findfirst in the Arduino IDE? Basic code below: #include "Arduino.h" #in...

Face Recognition with Blynk - Need Help Testing Sketch

If someone has a moment - probably half an hour - could they test this tutorial to see if the video part works? https://robotzero.one/face-recognition-with-blynk/ It's an Arduino sketch that sends data to an app on a mobile phone. It uses Blynk. I can't test the video stream works because I have a 4...

Re: Compressing Large HTML,CSS,JS files in ESP Progmem

In the end I used the CyberChef website to convert the HTML to the format I needed. I put it on my blog here: https://robotzero.one/esp32-cam-custom-html/

Add Another Command to arduino-esp32 CameraWebServer Example

I've added another url to listen for to the startCameraServer function from here: https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/Camera/CameraWebServer/app_httpd.cpp The code that is called with the URL looks like this: static esp_err_t servo_handler(httpd_req_t *req...

Re: Compressing Large HTML,CSS,JS files in ESP Progmem

Hi, Possibly one of the minifiers is removing something that is needed. Did you try using the web versions to see if something was stripped from the JS file. Sometimes comments in the code can cause a problem. I want to go the other way... I want to get the original HTML out of this file: https://gi...
