Blynk issue with ESP32CAM #537

Closed hms-11 closed 2 years ago

hms-11 commented 3 years ago

Blynk library version: 1.0.0 IDE: Arduino IDE version: 2.0 Beta 7 Board type: ESP32-CAM AI-THINKER Model Additional modules: N/A

Scenario, steps to reproduce

This problem has to failure modes, and two different ways to reproduce: 1) New Sketch - If you start with the BlynkEdgent example sketch, and include in the driver/header file for an ESP-32CAM using the Espressif provided driver (esp_camera.h) the sketch will fail to comply, with many errors (a sample is in "actual result").

2) If you attempt to adapt a previously working "Old" Blynk program to "New" Blynk by adding in the device template and device name, along with the appropriate authentication token the sketch will compile with no errors, the device will connect to wifi and the internet, but will not connect to the Blynk servers. If you go back to using "Old" Blynk auth token and remove the template and device defines, the program again works properly with the "Old" Blynk app.

Expected Result

Error 1) I feel there is a library conflict between something involving the new Blynk and the Espressif camera driver esp_camera.h (https://github.com/espressif/esp32-camera/blob/master/driver/include/esp_camera.h). The inclusion of this library causes the program to not compile.

Error 2) I expect it to connect to the Blynk servers as directed, again, it seems as if there is a conflict between something involving connecting to the new Blynk server when combined with esp_camera.h

Actual Result

Error 1) Compile errors, attached:

Error 2) The device continually attempts to connect to Blynk servers after establishing a wifi connection and fails.

hms-11 commented 2 years ago

I solved my issue, it isn't Edgent itself, my mistake, it is the included indicator.h file that causes the conflict.

I removed the 

#include indicator.h

in the 

BlynkEdgent.h

tab and all defines for it in 

settings.h
// #define LEDC_CHANNEL_1     1
// #define LEDC_CHANNEL_2     2
// #define LEDC_CHANNEL_3     3
// #define LEDC_TIMER_BITS    10
// #define LEDC_BASE_FREQ     12000

and it successfully compiled. I don't have access to my field test board until tomorrow but I'm fairly confident in a successful load. Hopefully I can connect to the cloud as well.
