Does esp32 camera slow down WiFi TCP transmission?

[RoyHsu67]

Hi~ I meet a situation. I can smoothly send data and image over TCP by esp32 WiFi module, but when I use esp32 camera to get a photo, once I call esp_camera_init(), TCP transmission becomes so much slow. A way to get better is to initialize camera driver, get a camera image, then immediately deinitialize camera driver, so I can recover TCP transmission speed and transfer image out. Is this normal?

I had the same problem, my wifi upload speed was only up to 30KB/s, when the camera started working

Hi @kxbin @RoyHsu67

Do you have solution for this issue?

I hit the same issue, the wifi transmission is very slow after esp_camera_init().
After calling esp_camera_deinit(), the wifi transmission looks fine.
