LVGL in ESP32 WROOM

I'm reusing a 2021's code (including ESP32 and ILI9341 pin out) developed in IDF4.0. In IDF5.0 with the LGVL old environment, the display does not show as expected. Please, refer to the 2 attached screenshots. The picture "FirstImage.jpg" shows the initial image and the picture "RefreshAfterFirstIma...

Re: IDF terminal - unreadable characters received from ESP32

@lukilukeskywalker your tip worked for me. Thank you! I added the two lines you highlighted (baud rate related commands) in the 'settings.json' file. Monitor works and the flash speed is somehow similar to how was before the change. And the warning 'C:\WINDOWS\SysNative\WindowsPowerShell\v1.0\powers...

IDF terminal - unreadable characters received from ESP32

Hi, it might not be an IDF problem, but I still ask to the community. The issue is related to output on terminal. And precisely the characters sent by ESP32. About one week ago, I started to receive this output from ESP32 x�x�x�x��x8xx�x��������x�������������������x�����8�8x�x��x�8�x���x��xx� Other ...

HTTP/TCP + UDP + ESPNOW

Has someone tested the combination in topic? I'm in IDF 5.0 and it seems to me that ESPNOW is not working. As ESPNOW tries a unicast I got "E (28335) espnow_example: Send error" "A stack overflow in task wifi has been detected" Anyhow, the feedback I'm looking at the moment is synthetized in the sub...

Re: REST architecture expansion

Hi ESP_Sprite, the solution with UDP works, but I'm still wondering why ESP32 acting in AP mode cannot run ESP_NOW. I'm looking in the components folder in release 5.0 and I find everything settle down for the combination - wifi AP interface and - ESP_NOW protocol Here below a short example of what ...

Re: How to get IP address?

look into (IDF 5.0) folder esp-idf\examples\common_components open protocol_examples_common.h and see the macro #define get_example_netif() get_example_netif_from_desc(EXAMPLE_NETIF_DESC_STA) in your code (after successful IP connection) esp_netif_ip_info_t ip_infoMyIf; esp_netif_get_ip_info(get_exa...

Re: REST architecture expansion

Hi ESP_Sprite, thank you for the reply. I did not know about ESP_NOW limit. Looking at "Kconfig.projbuild" I found in the "esp_now_example" (IDF 5,0) I see the following excerpt: ---------------------------------------------- menu "Example Configuration" choice ESPNOW_WIFI_MODE prompt "WiFi mode" de...

REST architecture expansion

Hi, this is a question on protocol architecture (in particular for ESP32 WROOM). The present architecture consists of a standard REST developed with IDF v5.0 libraries. The AP is also an HTTP server and STA(s) plays as HTTP client (both are ESP32 WROOM). The HTTP server offers an HTML interface to t...

Re: How to get "esp_netif_t *esp_netif" ???

Hi. I connect to this post with the aim not to duplicate. I'd like to assign the property 'host' of a http_client. The 'host' is also the AP and therefore it would be sufficient to retrieve the IP address of the gateway. I would like to leave as-is the example-connect section (just to be clear, now,...
