Hello. I connect to esp_eye and when i go to http://192.168.4.1/face_stream in browser i see: This URI doesn't exist

This error in monitor: W (324614) httpd_txrx: httpd_resp_send_err: 404 Not Found - This URI doesn't exist

Can you help me?

[me-no-dev]

which example? on the web server it's http://192.168.4.1:81/stream

[energo5]

This example: https://github.com/espressif/esp-who/tree/master/examples/single_chip/recognition_solution

http://192.168.4.1:81/stream also not working

[XiaochaoGONG]

This example is dedicated for ESP-EYE with its specific functions, which are described in the README

[energo5]

I specifically bought esp-eye and try to run on it.

[energo5]

Hello. I try further work with ESP-EYE with this example https://github.com/espressif/esp-who/tree/master/examples/single_chip/camera_web_server Its normal build, flash. In monitor i see: I (1664) wifi: connected with WiFi110, channel 10 I (1674) wifi: pm start, type: 1 I (3204) event: sta ip: 192.168.1.69, mask: 255.255.255.0, gw: 192.168.1.1 I (3204) camera wifi: got ip:192.168.1.69

Browser print "cannot connect to server" when i goto 192.168.1.69.

After some time monitor print: E (129444) camera: Detected camera not supported. E (129444) camera: Camera probe failed with error 0x20004 E (129444) app_camera: Camera init failed with error 0x20004 I (129444) camera_httpd: Starting web server on port: '80' I (129454) camera_httpd: Starting stream server on port: '81'

Further i try this example https://github.com/espressif/esp-who/tree/master/examples/single_chip/detection_with_command_line Its normal build and flash. In monitor i see this last log lines: I (0) cpu_start: App cpu up. I (751) spiram: SPI SRAM memory test OK I (751) heap_init: Initializing.

and nothing else not happening when i see at camera with difference distance. Then after 2-3 minutes monitor print this: E (129157) camera: Detected camera not supported. E (129157) camera: Camera probe failed with error 0x20004 E (129157) app_camera: Camera init failed with error 0x20004 E (129157) app_process: Camera capture failed E (129167) app_process: Camera capture failed E (129167) app_process: Camera capture failed E (129177) app_process: Camera capture failed E (129177) app_process: Camera capture failed E (129187) app_process: Camera capture failed E (129187) app_process: Camera capture failed E (129197) app_process: Camera capture failed E (129197) app_process: Camera capture failed E (129207) app_process: Camera capture failed

The i try this example https://github.com/espressif/esp-who/tree/master/examples/single_chip/recognition_with_command_line Its normal buld and flash. In monitor i see last log lines: I (0) cpu_start: App cpu up. I (1054) spiram: SPI SRAM memory test OK I (1055) heap_init: Initializing.

I (0) cpu_start: Starting scheduler on APP CPU. I (218) sccb: pin_sda 26 pin_scl 27

and nothing happened when i see at ESP-EYE at difference distance. After 2 minutes monitor print:

E (129238) camera: Detected camera not supported. E (129238) camera: Camera probe failed with error 0x20004 E (129238) app_camera: Camera init failed with error 0x20004 E (129238) app_process: Camera capture failed E (129248) app_process: Camera capture failed E (129248) app_process: Camera capture failed E (129258) app_process: Camera capture failed E (129258) app_process: Camera capture failed E (129268) app_process: Camera capture failed

What you can say? Its mean that ESP-EYE not working and i must return ESP-EYE to seller?

[XiaochaoGONG]

Hi, for all the undetected message, did you check your configuration that maps the camera pins to the right device ? You can run idf.py menuconfig then find the ESP-EYE mapping. By default, the mapping is for WROVER-Kit.

[energo5]

I checked camera pins. In this examples "detection_with_command_line" and "recognition_with_command_line" i see that WROVER-KIT already selected:

[XiaochaoGONG]

So you need to change to ESP-EYE pin, entering the Select Camera Pinout, there is an option for it.

[energo5]

After select pins for ESP-EYE this examples "camera_web_server", "detection_with_command_line" and "recognition_with_command_line" started work right. But example "recognition_solution" still no work. I can not find CAMERA PINS in menuconfig: How set pins in this example?

[energo5]

Hello. Can you help me with this error - https://github.com/espressif/esp-who/issues/115#issue-500048485 in example "recognition_solution"?

[XiaochaoGONG]

Hi @energo5 please follow the key process of recognition_solution. The basic idea is to firstly awake the device, then to connect to the network, then to do face detection.

[energo5]

Hello The problem was that I didn’t turn on the downloaded greeting recording loudly. It did not work, and I commented on these lines in the code to skip waiting for a greeting:      while (g_state == WAIT_FOR_WAKEUP)          vTaskDelay (1000 / portTICK_PERIOD_MS); After that I got the error https://github.com/espressif/esp-who/issues/115#issue-500048485

Now I turn on the greeting record loudly and everything is working. Tell me how to bypass the waiting code in the code?

[XiaochaoGONG]

Change the WAIT_FOR_WAKEUP to WAIT_FOR_CONNECT https://github.com/espressif/esp-who/blob/19123aaeae5f0ac1fff434df5ee65a823b6fabea/examples/single_chip/recognition_solution/main/app_main.c#L99 and https://github.com/espressif/esp-who/blob/19123aaeae5f0ac1fff434df5ee65a823b6fabea/examples/single_chip/recognition_solution/main/app_httpserver.c#L347

[energo5]

Its worked. Fine. Thank you very much.
