Meanwhile I figured out that the event handler (event_id WIFI_EVENT_SCAN_DONE) returned event status = 1. Which means that scan process terminated unsuccessfully. This was caused by esp_scan_stop(), accidentally called by application at the wrong time. Scan got stopped prematurely after one second a...

What problem? Please have a look at my question. Sorry, but your response is not helpful. The scan function may work with your Arduino example. But as I told, it does not work in our case. I'm looking for someone who is interested in helping me localizing and solving the problem. Disclaiming the pr...

Hi,
with simple sketch in arduino (esp-idf 4.4) it seems to work:

Congratulation! So how could this help to solve the mentioned problem? I don't understand.

Configuration: ESP32-S2-WROVER (4MB) with ESP-IDF v5.0-dev-4770-gd622bcfd46 WiFi is running in mode WIFI_MODE_APSTA Problem: WiFi-Scan does not list stations of all channels. wifi_config_t wifi_config_ap = \ { .ap = \ { .ssid = WIFI_AP_SSID, .ssid_len = strlen(WIFI_AP_SSID), .channel = 2, .password ...

I followed step 7 and used command "esptool.py write_flash" This ist the prompt I get: Executing action: bootloader Running ninja in directory /home/project/build Executing "ninja bootloader"... [1/1] cd /home/project/build/bootloader/bootloader.binBootloader binary size 0xa000 bytes. 0x1000 bytes (...

Thank you for clarifying.

Hi Mahavir, thank you for your reply. Did you try to rebuild bootloader with new flash configuration and use that image? I used the command "idf.py bootloader bootloader-flash" to flash the secure bootloader first. Alternatively, I would recommend that you try flashing command as it is generated dur...

Equipment: ESP32-S2-WROVER with SDK esp-idf.v5.0-dev-4770-gd622bcfd46 https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/dfu.html "USB DFU" worked fine until "secure boot" got enabled. With "secure boot" enabled, ESP32-S2 can't be recognized as DFU device any more. I couldn't r...

And I have figured out that replacing "--flash_size keep" with "--flash_size 4MB" solves the problem.

I was wrong. It doesn't solve the problem. Flashing works, but the flashed image seems to be corrupt.

Hello! Equipment: ESP32-S2-WROVER with SDK esp-idf.v5.0-dev-4770-gd622bcfd46 The Problem: flashing above flash offset of 2 MB fails if secure boot is enabled Executing "idf.py flash" results in the following error message once the area > 2 MB is going to be flashed: "A fatal error occurred: Failed t...
