I'm using serial Bluetooth so a user can set Wi-Fi details and read the IP address from a phone. I want to kill the Bluetooth connection when either: a) The details have been entered correctly (via Bluetooth) b) The device restarts and the user has viewed the IP address on their phone (via Bluetooth...

Thanks for the tip. I've done this which seems to work... #include <Arduino.h> #include <BluetoothSerial.h> BluetoothSerial SerialBT; const char *bluetooth_name = "robot01"; bool bluetooth_disconnect = false; void callback(esp_spp_cb_event_t event, esp_spp_cb_param_t *param); void setup() { Serial.b...

Hi Mad scientist, I am trying to do like you did and have the servo and cam both work at the same time. Can you explain how you got around sending servo and the cam over wireless at the same time? Thank you very much Here's how I did a pan and tilt platform with the ESP32-CAM - https://robotzero.on...

Might be a bit late in the day for this but I used websockets for two-way communication here: https://robotzero.one/esp-who-recognition-with-names/

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";...

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...

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...

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...

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/

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...
