Hi, I would like to understand with is going on with the following code. With the macro ESP_NETIF_SNTP_DEFAULT_CONFIG(CONFIG_SNTP_TIME_SERVER); it should be creating single entry (position zero), then the config.index_of_first_server = 1 points to position one, that should crash on setup? Can someon...

Hi, I would like to know how is the IP_EVENT and WIFI_EVENT value derived?. In my program, is it possible to register and deregister the esp_event_handler_register and esp_event_loop_create_default() multiple times ? esp_netif_init(); esp_event_loop_create_default(); esp_netif_create_default_wifi_st...

Hi, I am looking if this is possible and if there is an example code around? 1) The Ethernet (W5500) connects to a device and provides DHCP (DHCP server running on Ethernet port). 2) Data received from Ethernet is processed. 3) Data is then sent out through the WIFI STA (DHCP is from AP). Device <--...

Are you able to connect to Wifi with non PSRAM module?

If you are going to use the IRAM memory there are limitation that you must be aware off. https://esp32.com/viewtopic.php?t=23891#p94825

These are good strategies, I guess there are no possibilities to change the heap allocation strategy of malloc to first get D/IRAM and then switch to DRAM, reason ist that the DRAM section is larger than the D/IRAM section. So if malloc would first allocate from D/IRAM, the large contiguous block fr...

That's a good resource for heap analysis. Unfortunately nothing is said about heap fragmentation and how to best avoid it in order to get a large as possible contiguous block. Any more ideas? :) This should get the largest free block for the different memory types. size_t heap_caps_get_largest_free...

Hi, I have ESP32 Rev3 with IDF 4.4.5. If I compile firmware with PSRAM enabled and deployed onto a hardware without PSRAM then wifi will not connect. Is there a way to get that to work? CONFIG_ESP32_REV_MIN_3=y CONFIG_ESP32_SPIRAM_SUPPORT=y CONFIG_ESP32_DEFAULT_CPU_FREQ_240=y CONFIG_SPIRAM_BOOT_INIT...

Hi,

Is there a configuration that would auto detect the SPIRAM speed?

At the moment, the only way is to manually set the setting below to test.
