Have you tried reserving ULP memory via menuconfig already? Hi. Thanks for replying. We don't have a requirement to run code while in deep sleep, so I need more detail about your suggestion. Also, the "ulp" in the 3rd party archive is misleading and is not associated with the ESP32S3 power modes an...

***Update**** For completeness, below is the message when the add_library(), set_property(), and target_link_library() entries are removed from CMakeLists.txt, reporting undefined references which are defined in the lib_iaq_2nd_gen_ulp.a: ***** FAILED: wifi_prov_mgr3.elf ... c:/espressif/tools/xtens...

We want to place a 3rd party archive (.a) in RTC memory to preserve the state of the library during deep sleep. There are no state change issues in normal running or light sleep. Our CMakeList.txt contains: *** idf_component_register(SRCS "app_main.c" "...other source files...c" INCLUDE_DIRS "." EMB...

I've searched the forums for any methods for esp32s3 chip input voltage (3.3v) monitoring and found nothing. I assume this would be a common issue for battery powered applications. So I have two questions : 1. Is there a API function specifically for monitoring the esp32s3 3.3v chip input? 2. if not...

See the online API page at the link below: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-guides/jtag-debugging/configure-builtin-jtag.html The table in that section lists the ESP32-S3 pins and the corresponding USB signal pins. The table indicates that there is a 5V pin on the ES...

I am unable to get DPP_ENROLLEE to properly display the QR Code. I've tried a few changes with the ESP-IDF terminal settings with no success. I am using the ESP32-S3-DEVKITC-1 V1.1. IDE configuration data is: Operating System: windows 10 Java Runtime Version: 13.0.2+8 Eclipse Version: 4.21.0.v202109...

Update: I drilled down to the lowest level available to me and the function turning on this clock-like pulse is "register_chip7_phy". Its header says: **** /** * @brief Initialize PHY module and do RF calibration * @param[in] init_data Initialization parameters to be used by the PHY * @param[inout] ...

To better understand the power usage of my app, I commented out all of the appropriate Bluetooth calls that start up and enable bluetooth and implemented a 2 sec deep sleep loop. I used a ESP32-S3-DEVKITC, with a battery source and sensing Resistor for current usage and displayed the behavior on a O...
