Re: How to get "esp_netif_t *esp_netif" ???
You'll need to dive into "example_connect" since all of your WiFi initialization is apparently hiding in there. See https://github.com/espressif/esp-idf/blob/8bc19ba893e5544d571a753d82b44a84799b94b1/examples/common_components/protocol_examples_common/connect.c#L165-L200 and https://github.com/espres...

Re: Interfacing the Wroom32 with a 1.8v I2C Sensor
HDC2010 Why not supply it with 3.3v as well and save all this trouble? Why do you need the 1.8v rail at all? Is there something I'm missing? Is there not the corollary of the ESP32 being able to recognize a low voltage one ? There is, that's why Sprite is suggesting either a level shifter to bring ...

Re: Vote on new vscode esp-idf extension setup UI
Hi Brian, I've butchered your great mockups to present what would be, for me, a much more valuable concept (if you can look past the ugliness). It is based on a few assumptions: 1. People initially just want it to work with the least hair torn out as possible. Set up whatever is needed to get them b...

Re: What would you like to see in The Next Chip?
The same capability as at least one new competing product to maintain WiFi connection with average current <50uA.

Re: Automatic Light Sleep
Setting those options via menuconfig ensures the functionality is included in the build, but you then need to enable it at runtime via esp_pm_configure() with esp_pm_config_esp32_t::light_sleep_enable = true. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/power_mana...

Re: ULP WAKE function and Main CPU interruptions
You're using the wrong mask here:
You want RTC_CNTL_SAR_INT_ST_M
See:
https://gist.github.com/igrr/4b002047fc ... main-c-L31
Code: Select all
ESP_ERROR_CHECK( rtc_isr_register(&ulp_isr_handler, NULL, RTC_CNTL_ULP_CP_INT_ENA_M) );

Re: ESP32 SoftAp static ip config
Also MY_IP_ADDR is a string representation of an IP so htonl is not doing what you expect:
You can use inet_addr or inet_aton to convert that to an IP, or use IP4_ADDR/esp_netif_ip4_makeu32 macros.
Code: Select all
#define MY_IP_ADDR "192.168.4.56"
dest_addr.sin_addr.s_addr = htonl(MY_IP_ADDR);

You already got some very helpful answers here: https://github.com/espressif/vscode-esp-idf-extension/issues/161 (Actually it looks like this was just approved but you posted much earlier, so sorry for the attitude) Perhaps a VS Code task that builds and then executes the command provided by pwmb wo...

Re: I want to make an interrupt while deep sleep
You can configure an RTCIO interrupt without enabling wakeup. Read the int on wake, and clear your counter if set.
