Re: Does esp_wifi_connect() adjust threshold.authmode during scanning process?

So you're saying that so long as I keep the default threshold.authmode at CONFIG_ESP_WIFI_AUTH_OPEN, pmf_cfg.capable at 1 and pmf_cfg.required at 0, the esp_wifi_connect() api will find all APs and apply the correct security level to the AP that matches the SSID provided? If that's the case, then ...

Does esp_wifi_connect() adjust threshold.authmode during scanning process?

I'd like for my ESP32-S3 to connect to any WiFi station, irrespective of its security setting. After initiating esp_wifi_start() and providing the WiFi credentials during the wifi provisioning process, I currently have to disconnect the wifi connection, scan and retrieve security setting of the WiFi ...

Re: ESP32-WROOM-S3 WiFi Connection issues

Interestingly enough, I'm having a similar issue with my WiFi connection for ESP32-S3. I'm switching WiFi networks too. Worked fine with the first one, not so great with the new one. Same code in both cases. Here's a link to my question (with code and logs): viewtopic.php?t=47692.

Inconsistent connection to WPA3-Personal-Transition security mode

I'm trying to connect ESP32-S3 to any WiFi AP irrespective of its security mode following a successful WiFi provisioning process. Here's my code:

ESP_ERROR_CHECK(wifi_prov_mgr_start_provisioning(security, (const void *) sec_params, service_name, service_key)); //This completes successfully and ...

Re: Modify a CMakeLists.txt that is managed automatically

Did you ever figure out how to use the Fasani library? I'm curious because I'm stuck too.

Re: How to check condition of ESP32-S3 wifi hardware?

Both ESP32-S3 boards I'm using are connected to the same network and get their power from the same USB hub. Why one of the boards works perfectly well, while the other keeps on disconnecting/reconnecting (after a long long time) is mind boggling. Is there something in the driver code that I can ...

How to check condition of ESP32-S3 wifi hardware?

I have a wifi provisioning code which allows esp32-s3 to connect to a wifi ssid successfully. But shortly thereafter, it disconnects from the wifi network. This problem began suddenly after working perfectly fine for several days with the same code. The same code works perfectly fine on a second ...

Re: LVGL 9.1.0 and lvgl_esp32_drivers compile errors

Does anyone know of any good alternatives to LVGL? I'm working with ESP32-S3 WROOM and need to display images in jpeg and png formats. LVGL documentation is not really helpful and I can't get things to display on my ST7701 driver based display unless I first manually convert an image into LVLG's ...

Re: How to improve http client time to download image?

Increased output_buffer on the heap with char *output_buffer = (char *) calloc(sizeof(char), 8192) . Also adjusted MAX_HTTP_OUTPUT_BUFFER in esp_http_client_read_response(client, output_buffer, MAX_HTTP_OUTPUT_BUFFER) to 8192. Definitely reduced the number of iterations in the do while loop to ...

How to improve http client time to download image?

Connected ESP32-S3 chip to node.js server on local machine. Smart phone app instructs ESP32-S3 (over mqtt server) to download image from node server. It takes ~30 seconds for ESP32-S3 to download ~100KB image and display on LCD screen (most of the time consumed by downloading process). Why so slow ...
